During the DLC livestream, I noticed a particular taxonomic error in the UI.
Frontier UI devs, Pteranodon is not a dinosaur; pterosaurs are separate groups of reptiles from dinosaurs.
To add to this:
Muttaburrasaurus has been called a Hadrosaur for over a year and a half now, with no signs of it being corrected; they're rhabdodontids, which are a separate kind of Iguanodont from hadrosaurs. It should be redefined as an Iguanodont, as that is much more taxonomicly correct.
If there's any other taxonomic errors in the game, please post them here!
