Please help with decision for Spinosaur

So, I am split. As you know, more evidence has emerged with the discovery of the full skeleton of Spinosaurus Aegypticus. What especially stood out to me was it's tail. As you know, the Spinosaurus from the "Jurassic Park/World" series is modified for a more terrestrial (land based) lifestyle than it's scientifically accurate counterpart.

However, Jurassic Park 3 did get something about it right: The Spinosaurus WAS an excellent swimmer.

My updates have been...lacking, I know. Real life has been kicking my rear.

In 2021, I lost the closest man I had to a father. He had gotten COVID-but that isn't what killed him. He had worked in a steel mill for many, many years-breathing in the air full of chemicals and smoke from processing the steel. When he went on Oxygen to help him get enough to fight on COVID...well...that lifestyle showed it's consequences and holes formed in his lungs.

My PTSD-induce Depression reared it's ugly head again...you may not know that I have high-functioning Autism...so staff in Middle School...well...abused me. Reliving that in my sleep-especially the ones who used mental and emotional manipulation vs physical...well...affected my mental state.

With the death of my father figure, the computer he had that I used for my stories was disconnected and moved somewhere.

I've been unsuccessful job hunting since I graduated with a major in Environmental Biology and minor in Museum studies. All the job openings I've been notified have been Cashier (which I was never trained for) and requires YEARS of actual experience. Plus there is the added stipulation that I need to make over a certain amount to cover what my disability insurance covers for medication as working would cause me to lose part of said insurance: which means I have to be even more selective on top of that.

Now-the only other computer I can use: my family's laptop-is literally falling apart. I'm not kidding. It's acting up more and more and the case keeping the components in place is held on by duct tape.

Moving on: I DO have ideas for Spinosaur. Jurassic World Alive has helped with creativity... but there are some ideas and questions I want to run by fans to see how they will be accepted first:

1) Should the bonded Spinosaurus's tamed by Harry and my OC regain the scientifically-accurate tails: Shaped more like crocodilians or tadpoles to further enhance their swimming abilities?

2) I'm split with the pairing? Should Harry be with Hermione Granger, Daphne Greengrass, Susan Bones, or a combination of two or all...somehow?

3) There are new dinosaurs in Jurassic World Alive I want to include that could fit into the Jurassic Park Era: Before the Hybrids and Gen 2's. Who should get the creatures below. Remember-one per magical:

Ichthyovenator (Spinosaur)

Vectispinus (Spinosaur? Possibly?)

Concavenator (Charcharodontosaur with sail)

Charcharodontosaurus

Ceratosaurus

Compsognathus

Gorgosaurus

Majungasaurus

Megalosaurus

Monolophosaurus

Pteranodon

Rajasaurus

Sinraptor (Actually a Metrocanthosaur)

Skorpiovenator (abelisaur)

Tarbosaurus

Troodon

Yutyrannus

Voldemort and some villains will also bond with a carnivore from the list above...though Voldemort's should be as dangerous as the largest predator: Spinosaurus.

Confirmed wizards/witches:

Voldemort (Imperius Curse)-foil to Harry

Wormtail/Peter Pettigrew-foil to Sirius

Fred Weasley

George Weasley (twins should get the same species)

Charlie Weasley (due to his fascination with dragons, why wouldn't he jump at a chance at a dragon-like creature)

Tracy Davis

Fleur Delacour

Remus Lupin

Nymphadora Tonks

Walden Macnair (Death Eater)

Bellatrix Lestrange-foil to Hermione

Hagrid

Hannah Abbot

Cedric Diggory

Cho Chang

Padma Patil (her sister not mature enough before the...Incident at Island 1)

Penelope Clearwater

Antonin Dolohov (Death Eater)
