Model of a dinosaur egg. Dinosaur reproduction shows correlation with archosaur physiology, with newborns hatching from eggs that were laid in nests. [1] [2] Dinosaurs did not nurture their offspring as mammals typically do, and because dinosaurs did not nurse, it is likely that most dinosaurs were capable of surviving on their own after hatching.

The enduring popularity of dinosaurs, in its turn, has resulted in significant public funding for dinosaur science, and has frequently spurred new discoveries. In the United States, for example, the competition between museums for public attention led directly to the Bone Wars of the 1880s and 1890s, during which a pair of feuding ...
No dinosaur egg has been found that is larger than a basketball and embryos of large dinosaurs have been found in relatively small eggs, e.g. Maiasaura. [53] Like mammals, dinosaurs stopped growing when they reached the typical adult size of their species, while mature reptiles continued to grow slowly if they had enough food.
Dinosaurs are unique in showing a perforate or open acetabulum, where the full extent of the socket is a hole without infilling bone. [1] acromion The acromion is a bony ridge on the outer distal end of the scapula that functions in providing an attachment for the clavicle.
Saurolophus (/ s ɔː ˈ r ɒ l ə f ə s /; meaning "lizard crest") is a genus of large hadrosaurid dinosaur from the Late Cretaceous period of Asia and North America, that lived in what is now the Horseshoe Canyon and Nemegt formations about 70 million to 66 million years ago. It is one of the few genera of dinosaurs known from multiple ...
Dinosaur bones weren’t exactly new discoveries, but the explanations were. Many of the same bones that Buckland imagined as belonging to a megalosaurus had been found in the 17th century ...
The Princeton Field Guide to Dinosaurs garnered positive reviews upon its release. Reviews published by Wired and the National Audubon Society, for instance, praised the book's extensive coverage of dinosaurs and its many illustrations, though noted that it may be written in a too technical manner to appeal to children and "casual dinosaur fans".
Flour the foot of a toy dinosaur to avoid sticking. Press the foot down into each ball of dough to create a footprint. Fill the footprint with jelly or jam of your choosing.
