- Non-standard. "Dinosaur" as a modern concept encapsulates a very broad selection of drastically differing varieties of animal, of which their only similarity to each other is being extinct. Given a fantastical environment without this shared commonality, "dinosaurs" are not practically spoken of under a blanket terminology. Speaking broadly of "large reptilian monsters," one could be talking about any number of fanciful beasts, many of which would not be dinosaurs by any stretch of the definition.
Some cultures group theropods with other large terrestrial avians, such as ostriches. Northern cultures may not distinguish significantly between small pterosaurs and birds. Ceratopsians share more in common behaviorally and in physical description with animals like rhinoceroses, and would never be lumped into a single grouping with an animal like a tyrannosaur, should both be encounterable.
That said, for the sake of clarity, and as an accessible reference guide, an index is provided here, for finding specific glossarium entries, organized by the real-world scientific (or common) name of the dinosaur. Other prehistoric, non-dinosaur fauna are also included here for convenience.
