Sorry in advance,
Personal irrelevant bugbear;
Dinosaurs were not reptiles.Another really interesting fact about a Crocodile Monitor’s teeth is with the exception of the Tyrannosaurus Rex, it is the only other reptile to have its top and bottom teeth scissor across each other.
They had different metabolic systems and the giveaway is the leg position - no reptile has its legs underneath it like dinosaurs and birds did or do.
