OK I'm putting this list down for anyone who'd be interested in extinct animals being in Elder Scrolls other then the Saber tooth and Mammoth. I figured that Dinosaurs are more like modern animals the only attack when people are to close to them, provoked or are just hungry but since most Carnivores are massive I think that people would be not on their top menu since they wouldn't really fill them up and waist to much energy, Dragons would hunt the herbivores and since most Dragons like Smaug have a great sense of pride they would fight carnivorous dinosaurs on equal grounds and not use their fire or any breath attacks against them since dinosaurs like T rex would be a great challenge for them and they are smart enough not to attack a parent dinosaur.
Here's the list
Tyrannosaurus: Lives in forests
Tarbosaurus: Lives in forests
Allosaurus: Lives on open plains
Eoraptor: Lives in Dens
Herrarosaurus: Lives in Dens
Spinosaurus: Lives in forests or swamps
Ceratosaurus: Lives in forests
Dilophosaurus: Lives in forests
Velocoraptor: Lives in forests near large tree's close to a river or pond
Dromeosaurus: Lives in forests

Suchimimus: Lives near swamps
Carnotaurus: Lives in forests
Crylophosaurus: lives in Forests
Majungasaurus: Lives in forests

Daspletosaurus: Lives in open plains or Forests
Nannotyrannos: lives on open plains

Prehistoric Sharks during the age of the Dinosaurs not Megalodon, damn thing is to big to add to it,
Dunkleosteus (not sure it would be a smart idea to add them but hey they eat sharks)
Prehistoric fish (Half for the ocean, since i don't know what would swim in the oceans of Elder Scrolls and the other half is for the Spinosaur family tree since they mostly eat fish)
Well that's pretty much all I can come up with but anyone who wants to leave a review please do so, I could use more dinosaurs and I'm sure Lelouch's adopted son Speckles would appreaciate it too.
