The dinosaurs and other animals in The New Dinosaurs were heavily influenced by the paleontology of its time. The ideas of the Dinosaur Renaissance – replacing the older ideas of dinosaurs as dumb and slow creatures with active, agile and bird-like animals – are heavily used in the book.[1] Dixon extrapolated on the ideas of paleontologists such as Robert Bakker and Gregory S. Paul when creating his creatures and also used patterns seen in the actual evolutionary history of the dinosaurs and pushing them to an extreme, such as with the creation of the "gourmand", an armless and massive scavenger descended from the tyrannosaurids[2] (Paul had also pushed the idea that hypothetical post-Cretaceous descendants of tyrannosaurids would have become armless and that the fossil record supported it,[4][5] although subsequent findings and research changed his mind).[6]
