“La lezione tratta dai tropici è chiara: per essere un grande animale terrestre di successo, devi resistere contro i mammiferi, e per fare ciò dovresti o essere tu stesso un mammifero, o almeno avere un metabolismo ugualmente alto. I grandi mammiferi hanno soppresso i rettili grossi nei tropici per gli ultimi sessantacinque milioni di anni. Quindi, come si può spiegare il successo dei dinosauri contro i mammiferi? Partendo dal presupposto che i dinosauri avessero metabolismi lenti? Non è tanto probabile.”

Predatory Dinosaurs of the World

The dinosaur world I grew up in was classical. They were universally seen as scaley herps that inhabited the immobile continents. There was no hint that birds were their direct descendents. Being reptiles, dinosaurs were cold-blooded and rather sluggish except perhaps for the smaller more bird-like examples. They all dragged their tails. Forelimbs were often sprawling. Leg muscles were slender in the reptilian manner. Intellectual capacity was minimal, as were social activity and parenting... Hadrosaurs and especially sauropods were dinosaurian hippos, the latter perhaps too titanic to even emerge on land, and if they did so were limited by their bulk to lifting one foot of the ground at a time. Suitable only for the lush, warm and sunny tropical climate that enveloped the world from pole to pole before the Cenozoic, a cooling climate and new mountain chains did the obsolete archosaurs in, leaving only the crocodilians. Dinosaurs and the bat-winged pterosaurs were merely an evolutionary interlude, a period of geo-biological stasis before things got really interesting with the rise of the energetic and quick witted birds and especially mammals, leading with inexorable progress to the apex of natural selection: Man. It was pretty much all wrong. Deep down I sensed something was not quite right. Illustrating dinosaurs I found them to be much more reminiscent of birds and mammals than of the reptiles they were supposed to be. I was primed for a new view.
