End of Oak Street in the Morrison formation
so I just got back from seeing the movie and had an absolute blast!
but, being the little palaeo-nerd that I am, the biggest gripe I had with the film was that it had dinosaurs from all over, both geographically and chronologically. while it was nice to see my fav Coelophysis finally getting some recognition, I’d have much preferred the story take place in one period and in one formation.
in my mind, Marshosaurus could be a very good replacement for the film’s Coelophysis, as it was about the size that it was in the movie and would fill that smaller predator/scavenger role well. Camptosaurus could work well for that short moment of an Ankylosaurus getting got by the sneak attack Allosaurus, as it would be more or less the same size and not covered in armour that would make it a trickier prey item. finally, as nice as it is to see a Spinosaurus, I’d replace it with Allosaurus’ “underdog”, Ceratosaurus; let it have some spotlight out from beneath Allosaurus’ shadow for once and allow it to be a proper threat, even if it’s not nearly as big as Spino (I’d considered suggesting Torvosaurus, but that might just look like Allosaurus 2 and confuse casual viewers)
I don’t know much about non-dinosaur mesozoic life, so I can’t really comment on the pterosaurs and erythrosuchids, but I’m happy to hear suggestions!
