Dolichoiliac refers to one of two principal hip bone configurations in early saurischian dinosaurs. The dolichoiliac type is characterised by large front and back extensions of the ilium as well as elongated and narrow pubes and ischia. In contrast, the brachyiliac type is characterised by short ilium extensions and more robust pubes and ischia ...
Their early work can be seen today in the Crystal Palace Dinosaurs, constructed in the 1850s, which present known dinosaurs as elephantine lizard-like reptiles. [5] Despite these reptilian appearances, Owen speculated that dinosaur heart and respiratory systems were more similar to that of a mammal than a reptile.
The idea of dinosaurs as ectothermic remained a prevalent view until Robert T. Bakker, an early proponent of dinosaur endothermy, published an influential paper on the topic in 1968. Bakker specifically used anatomical and ecological evidence to argue that sauropods, which had hitherto been depicted as sprawling aquatic animals with their tails ...
"Their bodies were shaped for speed and agility, and their teeth were adapted for specific diets," Heath said of the early dinosaurs. For example, Herrerasaurus was a 20-foot (6-meter) long ...
This category is for pages relating to dinosaur anatomy, such as physical features or parts. For anatomic features which are not possessed solely by dinosaurian groups, (such as the Triceratops neck frill which is also employed by the Frill-necked Lizard ), they may be included if it is fairly evident or common in dinosaur anatomy overall.
Description of the anatomy of the appendicular skeleton of Bagualia alba is published by Gomez et al. (2025), who also study morphological diversity of sauropodomorphs throughout their evolutionary history, and report evidence of shifts in morphospace occupation during the Jurassic related to the diversification of early sauropods and ...
Ingentia was an early member of a dinosaur group called sauropods that later included Earth's biggest terrestrial creatures including the Patagonian behemoths Argentinosaurus, Dreadnoughtus and ...
