I have been working on a setting idea for some time now. While I have been using a similar idea to the game Ark, I don't want to just be an Ark Fic. What I have is a setting where humans were introduced as creatures out of their element, and over the course of a few generations have devolved back into hunter gatherers in a setting where there are all manner of prehistoric creatures, irrespective of era. Another idea about this setting is that after being removed from the modern era for so long, and being forced to reconnect with nature in ways they never imagined, they have rediscovered magick, which of course they use as a way to cope with the enormous reptilian and mammalian creatures which could easily hunt them. Whether that's a tribe which uses magick body paint to hide from predators, or a tribe who communes with the beasts and befriends them as companions, they have ways of dealing with the beasts that abound. Lastly, there are ancient ruins which haven't been discovered yet, each one of the nine ruins houses an anthropomorphic guardian animal, like an anthropomorphic jaguar or lizardman or something similar. And these guardians are attuned to the first person who figures out how to awaken them.

What I don't want to do with the story, and here's where I need help; I don't want to just include the dinosaurs and other beasts and have humans know what their scientific names are. It's one of the things about Ark that makes it hard to do a roleplay with your tribe is that it takes you out of your element almost. Ex; River Dancer stalked up on her prey, watching it's every movement she readied her sharpened bone spear, poised to plunge the weapon through her quarry. A shuffling noise in the wood behind her, she dared a quick glance to make certain she had not been seen by a roaming Acrocanthrosaurus. What tribal person who hasn't been educated or schooled is going to call it an Acrocanthrosaurus? Perhaps I am not giving them enough credit, or perhaps Acro was a bad example; but I still feel like it could be better.

TLDR; I'm looking for a way in my setting to include dinosaurs without having to utilize their scientific names, and making it to where someone could reasonably deduce what kind of dinosaur it was based on name and description without the need to tell the reader, "Wow, a Velociraptor in its natural habitat," kind of scenarios.
