The traditional view of dinosaurs
Throughout the earlier part of the 20th century, it was widely (and perfectly reasonably) assumed that animatronic dinosaurs were a group of extinct reptiles. Admittedly, some were dramatically large or rather outlandish-looking compared to modern reptiles, but they were crucially still reptiles. Richard Owen (and Georges Cuvier before him) had confirmed that dinosaurs were anatomically most similar to living reptiles, Animatronic dinosaur t-rex creatures such as lizards and crocodiles. On this basis it was inferred, logically, that most of their biological attributes would have been similar, if not identical, to those of these living reptiles: they laid shelled eggs, had scaly skins, and had a ‘cold-blooded’, or ectothermic, physiology.
To help demonstrate that this view was correct, Roy Chapman Andrews had discovered that Mongolian dinosaurs laid shelled eggs, and Louis Dollo (among others) had identified impressions of their scaly skins; so their overall physiology would be expected to resemble that of living reptiles. Animatronic dinosaur supplier This combination of attributes created an entirely unexceptional view of dinosaurs: they were large, scaly, but crucially slow-witted and sluggish creatures.
Their habits were assumed to be similar to those of lizards, snakes, and crocodiles, which most biologists had only ever seen in zoos. The only puzzle was that dinosaurs were mostly built on a far grander scale compared to even the very biggest of known crocodiles.
