Allosaurus Had Never Seen Such Bullshit Speculative Story Fanfic Before

Summary: 140 million years in the Late Jurassic of the Morrison Formation, North America. A male Allosaurus goes through his day-to-day life and it gets weirder and stranger as the day progresses as he engages in strange behaviors.

It starts in the second portion of the Dinosaur Hall in the Natural History Museum of Los Angeles as Thomas appears behind a fossil display of two skeletons of Jurassic dinosaurs. "Carnivorous dinosaurs are what catches the eyes of people, their sharp teeth to kill and eat flesh, sharp claws, bellow roars, they can range from the larger famous T. Rex to the small and cunning Velociraptor. Before these dinosaurs were well-known, there was another famous carnivorous theropod." Brings out a cast model of the Theropod. "Allosaurus. The Lion of the Jurassic has the average theropod body plan. Its name means "different lizard", alluding to its unique (at the time of its discovery) concave vertebrae. Allosaurus was one of the first well-known theropod dinosaurs, it has long attracted attention outside of paleontological circles. It was the most abundant predator of the Morrison formation during the late Jurassic, it lived alongside and preyed on dinosaurs behind me like Camptosaurus and Stegosaurus. Paleontologists interpret Allosaurus as having had cooperative social behavior and hunting in packs, while others believe individuals may have been aggressive toward each other and that congregations of this genus are the result of lone individuals feeding on the same carcasses. But what was an Allosaurus's life really like it would have been weird and complex to us humans don't you think so?"

The Morrison Formation 140 million years ago during the Late Jurassic. It is now near the beginning of the wet season. The recent rains have allowed many plants to grow and take seed and with an abundance of plants leads to an increase in the population of herbivores. In the fern prairies alongside cycads and shrubs, a flock of Dryosaurus nip on the newly growing shoots as one sentry keeps an eye out for danger. Lurking among the trees, tree ferns, and shrubs is a young male Allosaurus about 14 years old, being a young juvenile his legs were relatively long and the lower segments of the leg, the shin, and the foot were relatively longer than the thigh. A younger Allosaurus like him were faster and had different hunting strategies than adults, chasing small prey as juveniles, then becoming ambush hunters of large prey upon adulthood. His soft pads cushion his feet as he stalks the forest floor and blends in with the foliage.

Once closer and closer, the Allosaurus changes out of the foliage. The Sentry lets out an alarm as the Flock scatters and runs with the predator in pursuit. The young male Allosaurus looks for a weak target within the flock, the Dryosaurus's main defense now is speed, and with their strong long legs and stiff tail for counterbalance make these ornithopods agile and fast runners. Soon the Allosaurus finds his target, a straggler he cuts her off from the flock and chases her throughout the fern prairie towards the shrub suddenly, the Dryosaurus stumbles on her step and as she tries to get up she is grabbed and killed by the Allosaurus as he crushes her in his jaws. Allosaurus grasps his prey similar to that of modern big cats with their forelimbs and then makes multiple bites on the throat to crush the trachea. Soon the Allosaurus feasts on his latest kill although this would only sustain him for a short amount of time, he needs something greater to satisfy his hunger.

The young male Allosaurus walks through the fern prairie plains of the Morrison Formation. This marks the arrival of the sauropods, herds of Haplocanthosaurus, Apatosaurus, Brontosaurus, Barosaurus, Diplodocus carnegii, Brachiosaurus, and Camarasaurus, which browse on the tree ferns and leaves of the branches of trees with some swallowing stones to help aid in digestion The latest new arrivals are Smitanosaurus which is a dicraeosaur sauropod and Amphicoelias. The gigantic sizes of sauropods, reached early in sauropod evolution, with very large-sized species present as early as the late Triassic period, and whatever evolutionary pressure caused large size was present from the early origins of the group. Modern giant mammalian herbivores today, such as elephants and rhinoceros, showed that larger size in plant-eating animals leads to greater efficiency in digesting food. Since larger animals have longer digestive systems, food is kept in digestion for significantly longer periods, allowing large animals to survive on lower-quality food sources. This is especially true of animals with a large number of 'fermentation chambers' along the intestine, which allow microbes to accumulate and ferment plant material, aiding digestion. The sauropods' digestive system, is well adapted to handle low-quality food, allowing for the consumption of ferns as a large part of the sauropod diet which are abundant here. Other benefits include relative immunity from predators, lower energy expenditure, and longer life span.

Other herbivores include small herds of Stegosaurus and Hesperosaurus alongside ankylosaurs including Mymoorapelta and Gargoyleosaurus, which feed on the low-growing ferns, cycads, and shrubs. Dryosaurus, Nanosaurus, Camptosaurus, and Fruitadens follow the herbivores eating on plant matter scraps left behind and insects disturbed by the feet of the large herbivores. Smaller lizard-like Sphenodonts Eilenodon, Opisthias, and Opisthiamimus feed on the horsetails while a Hallopus patrols the vegetation for small prey. The Allosaurus walks through the savanna and ignores everyone although receiving glares from the herbivores who have their eyes on him as he comes to a waterhole to drink.

Nearby, a Saurophaganax drinks from the waterhole, this theropod is twice the size of an Allosaurus and often competes with large theropods like Allosaurus driving them away from their kills, this time the young male Allosaurus drinks at another part of the waterhole to satisfy his thirst. A flock of Kepodactylus has also come to drink joined by a pair of Stokeosaurus and a larger pterosaur, Harpactognathus. A Diablophis feasts on a Rhadinosteus, a prehistoric frog while a Fruitachampsa basks close by on the banks of the waterhole. The male Allosaurus suddenly catches the smell of meat. The olfactory bulbs of Allosaurus were large and seem to have been well suited for detecting odors, although the area for evaluating smells was relatively small.

The young male leaves and follows the scent and comes upon a pair of Ceratosaurus who just took down a young diplodocus, another competitor of Allosaurus, these horned dinosaurs normally live in wetlands and waterways while allosaurus lives out on the plains, this niche partitioning reduces competition over the same prey resource. But the smell of a carcass is a beacon to scavengers as the Allosaurus approaches them alongside a Stokeosaurus and a pair of Tanycolagreus. The Ceratosaurus pair soon become becomes aggressive as they chuff and inflate their throat sacs at their arch-rival, the allosaurus is not deterred by their threat display. Soon the Ceratosaurus show their claws with their arms splayed and showing their gaping jaws of sharp teeth and hiss, the Allosaurus is not budging. Soon the female of the pair charges and snaps at the Allosaurus and chases him away.

The Allosaurus soon crosses a shallow river, Lungfishes including Ceratodus and Hulettia laze about in the bottom of the river floor only surfacing and taking gulps of air from the surface, two species of turtles, Dinochelys, bask on the logs and rock on the shores of the river, Cteniogenys, Amphicotylus lucasii, and Diplosaurus bask on the sand banks, and a group of Schillerosaurus basks on the large boulders to warm themselves up as the Allosaurus passes by them as a Fruitafossor digs out of the cliff face of the river sticking its head out. A Hesperornithoides snatches a Tinodon bellus from its burrow as Dryolestes looks down from a branch observing the young male Allosaurus.

The Allosaurus comes upon a few other Allosaurs feeding on a dead carcass of their own species. They are typically territorial and will kill and cannibalize intruders of the same species, and will also do the same to smaller individuals that attempt to eat before they do when aggregated at feeding sites. Individuals were drawn together to feed on other disabled or dead allosaurs and were sometimes killed in the process. With no other choice, he joins in the feast and suddenly, a Marshosaurus appears to feast on the kill, but the young male hisses and intimidates the theropod, soon the other allosaurs join in to scare off the theropod as he walks away in defeat.

Soon young Allosaurus returns home to their pack's territories, the young male sees his parents and siblings, it is a close family unit, as the offspring of the pack belongs to the mated pair alongside other allosaurs. His mother resting while his sibling's roughhouse hissing, snapping, and shoving one another and the young allosaurs join in on the action. The mother lays under the trees resting about and nearby in a series of burrows on a mound, mammals like Eurylambia, Comodon, and Morrisonodon sleep during the day only coming out at night to feed. The Morrisonodon has babies to look after as the multituberculate nurses her babies from special glands that give off milk. Most Allosaurus packs relax under the shade during the day to conserve energy and keep out of the hot sun. Although Allosaurus may have hunted in packs, it has been argued that Allosaurus and other theropods had largely aggressive interactions instead of cooperative interactions with other members of their own species. The study in question noted that cooperative hunting of prey much larger than an individual predator, as is commonly inferred for theropod dinosaurs, is rare among vertebrates in general, and modern diapsid carnivores (including lizards, crocodiles, and birds) rarely cooperate to hunt in such a way.

Allosaurus was quite intelligent having a more complex social structure, organized in a loose hierarchy based on size, age, gender, facial features, and behavior, the older individuals had bolder, larger head adornments and were dominant over their pack members. The Horns above and in front of the Allosaurus' eyes were composed of extensions of the lacrimal bones and varied in shape and size. There were also lower paired ridges running along the top edges of the nasal bones that led into the horns. The horns were probably covered in a keratin sheath and may have had a variety of functions, including acting as sunshades for the eyes, being used for display, and being used in combat against other members of the same species although they were fragile. The young male allosaurus rests under the shade as a herd of Camptosaurus walks by the young male allosaur and one of the individuals approaches him curiously. Normally the predator would lunge at the dinosaur, but in this case, the young Allosaurus as he is not hungry before the Camptosaurus leaves to join his herd.

Soon he notices his father leaving on the hunt and follows him to a clearing where an injured stegosaurus is browsing. The young male Allosaurus watches his father as he stalks close to an Adult Stegosaurus. This stegosaur has been bruised and scarred from many fights with predators and other stegosaurs and one encounter with a Saurophaganax left him with a wounded left hind leg and a bite to the shoulder. The Older Allosaurus runs in front of the Stegosaurus as the armored herbivore notices the predator bellows back in defense while swinging its spike thagomizer tail back and forth. The Older Allosaurus knows to avoid the Stegosaurs' main tail defense as they circled one another waiting for who would make the next move. As the stegosaurus swings its spike tail at the Predator, the allosaurus's main goal is to tire the prey out. The Stegosaurus charges and rears up on its hind legs using its tail for support to intimidate, but its injured left hind leg causes the Stegosaurus to slip giving the Allosaurus an opportunity. The allosaurus grabs the Stegosaur in the throat while slashing its chest with its claws and using its right-hand claws to grip its bite-mark shoulder to push its prey down. After delivering the killing blow, the theropod feasts and soon the carcass attracts scavengers as a trio of Ornitholestes appear from the bushes they wait for the large predator's jaws and teeth to break open the carcass which is easier for the smaller predators, the small theropods grab some pieces of meat with their arms and jaws although when the older Allosaurus notices them, he hisses and growls at them snapping his jaws sending them running. For the Young Allosaurus, this is a learning opportunity when he learns to take down large prey.

A few months had passed, and the mating season for the Allosaurus has arrived. For the young male, this is the time for him to leave his family pack and start a family pack of his own. Young individuals from other family packs and outsiders have come here to this dry clearing to mate and for older couples to renew their bonds. The young male Allosaurus finds his spots and gets to work, he starts by spreading his arms and bellowing with his throat sac, his rumbles can be heard for miles and his song joins the symphony of other Allosaurs. Soon a female approaches him, and the male Allosaurus continues to do his routine swaying his head back and forth and showing his brow hornlets. Then he does something unthinkable and unexpected, he gestures to the female while inflating balloon-like air bladders emerging from the top of their heads and coming between the holes in his hornlets, nasal sacs, and the top surface of his head. These inflatable air sacs as a way to show how healthy he is and soon the female joins in inflating her nasal sacs and bellowing with her throat. Soon they both stopped as the female accepts him as her mate they both nuzzle each other with their snouts

Soon another Allosaurus comes towards the new couple, a challenger as he hisses at them. Confronted by his rival, the Young Male allosaurus hisses back, he shows his teeth and claws to intimidate him. But he is not backing down, soon it leads to a brawl. Both allosauruses start biting one another in the snouts their teeth piercing their sensitive skin and then it turns to wrestle as they slammed their chests and claw at each other's shoulders as they continued biting some of the Allosaurus mostly the elders ignored this scene others the young ones including the female watch on. The young male Allosaurus bites his challenger's throat as he pushes and throws him off as his rival lands on the ground. The young male Allosaurus places his right foot on his rival's neck and growls, a warning at him, he lets him go and chases him out. This fight has also proven to the young female that he is a successful fighter as she approaches him and allows him to mount her.

A few weeks later, the start of the dry season has come, and the newly mated pair now join the other allosaurus on a hunt. Allosaurus, usually solitary, have been forced to band together into a large mob as there is no longer enough food to sustain lone hunting. After establishing their pecking order and allowing the larger, more aggressive individuals to become dominant, the band of predators is ready to hunt. Most of their usual prey has migrated in search of greener lands or succumbed to the drought and died. Together, they patrol the semi-arid dry savannas in search of food, they hear a loud rumble in the distance, the structure of the inner ear was like that of a crocodilian, so Allosaurus probably could have heard lower frequencies best, and would have had trouble with subtle sounds as they followed the sound they stumble across a small herd of Brachiosaurus. At 12 meters in height and with a weight of up to 60 tonnes, these immense sauropods would be avoided by the Allosaurus at any other time of the year. they see a herd of Brachiosaurus on the move led by a young adult female and an Elderly Female. These titans dwarf the Allosaurus in size, but the Allosaurus have numbers on their size. But desperate times call for desperate measures. The gang prepares to hunt. All the members get into their appropriate positions. The younger allosaurus with the mated pair joined them and start off hiding in the bushes, the young male rustled against the branches with a few snaps on purpose causing the Brachiosaurus hearing the sound to worry and panic.

Now they attack, The younger allosaurs burst from their cover and charge straight at the herd. Startled, the Brachiosaurus elderly female bellows to the herd to run as they turned and stampede. Allosaurus is equipped with dozens of sharp, serrated teeth with saw-like edges. The teeth became shorter, narrower, and more curved toward the back of the skull. As the young Allosaurus chase the Brachiosaurus at top speeds of 30 to 55 kilometers per hour (19 to 34 miles per hour). One brachiosaur runs separately from the rest. The allosaurs lock onto their target and race behind the giant as it flees. It is driven towards the older animals, who charge out from the sides, cutting off the brachiosaur's escape route and ensuring it runs in only one direction into a trap. At the end of the path of the chase, the largest allosaur lies in wait. His job is to deliver the fatal blow; to attack the throat of the brachiosaur. But he must get it right as he has a choose the right moment to strike to jump just the right height to reach his prey's neck and cling to the side of his quarry with the right strength so that he doesn't fall off. If he succeeds, he will have his slicing teeth and slashing claws to deliver fatal wounds to his prey's neck, The brachiosaur will collapse and die from blood loss and the allosaurs will have enough meat to last them for days, perhaps more, especially if the others end up fighting and killing each other over who gets the most food. Allosaurs seldom let the dead go to waste. If he fails, however, there is all likelihood that he will fall into the sauropod's path, and it will trample him beneath its 60-tonne bulk. His bones will break and his organs will be crushed, and he will be another victim of the drought. The brachiosaur will escape and the hunt will fail. However, not all the allosaurs will go hungry, as it is highly unlikely that they will let a sauropod-trampled corpse go to waste in a drought.

The brachiosaur reaches his position, pursued by the other allosaurs, dust kicked up by predator and prey alike. It's time to strike. The largest allosaur leaves his cover, runs directly into the titan's path, and jumps delivering a muscle-driven bite of its large prey, with the weaker jaw muscles being a trade-off to allow for the widened gape. The shape of the skull of Allosaurus limited potential binocular vision to 20° of width, slightly less than that of modern crocodilians. As with crocodilians, this may have been enough to judge prey distance and time attacks.

When delivering the blow the short teeth in effect became small serrations on a saw-like cutting edge running the length of the upper jaw, which would have been driven into prey. This type of jaw would permit slashing attacks against much larger prey, to weaken the victim. According to biomechanical analysis, the skull was very strong but had a relatively small bite force. By using jaw muscles only, it could produce a bite force of 805 to 8,724 N, but the skull could withstand nearly 55,500 N of vertical force against the tooth row. Allosaurus used its skull like a machete against prey, attacking open-mouthed, slashing flesh with its teeth, and tearing it away without splintering bones, unlike Tyrannosaurus, which is thought to have been capable of damaging bones. It is suggested that the architecture of the skull could have permitted the use of different strategies against different prey; the skull was light enough to allow attacks on smaller and more agile ornithopods, but strong enough for high-impact ambush attacks against larger prey like stegosaurids and sauropods. Allosaurus could open its jaws quite wide and sustain considerable muscle force. When compared with Tyrannosaurus and the therizinosaurid Erlikosaurus, Allosaurus had a wider gape than either; the animal was capable of opening its jaws to a 92-degree angle at maximum and that large carnivorous dinosaurs, like modern carnivores, had wider jaw gaps than herbivores.

The slicing teeth and slashing claws of the Allosaurus deliver fatal wounds on the Brachiosaurus' neck as it collapses and dies from blood loss, the other Allosaurus join in to finish it off. Soon after the Brachiosaurus succumbs to his wounds, the Allosaurus feed on the carcass that would sustain them for many days. They processed the carcasses by vertical movements in a similar manner to falcons, such as kestrels: the animal could have gripped prey with the skull and feet, then pulled back and up to remove the flesh. The young male Allosaurus and his mate as they feast on the Brachiosaurus, soon they will have a clutch of 20 eggs to start a new pack and establish their own territory and slowly build their way up the Allosaurus hierarchy in this Jurassic Primeval Planet.
