During the age of dinosaurs a group of reptiles existed, pterosaurs, which did fly. However, they are not dinosaurs and have never been classified as dinosaurs.]]>
’s bones were first discovered in Egypt in 1912. After being excavated, the skeleton was taken to a museum in Germany, where it was destroyed during World War II. The discovery of a new partial skull, among other materials and evidence, allowed paleontologists at the Civil Natural History Museum in Milan to produce new size estimates for

Dinosaur physiology is complicated and poorly understood. Because of general similarity to reptiles, dinosaurs were initially viewed as large lizards, with lizard-like body temperatures. As research continually showed close ties with birds, questions regarding the physiology of dinosaurs were reinvestigated. The answers have been elusive and how dinosaurs regulated their body temperatures remains an active area of study.]]>
Jurassic Park, what dinosaur was discovered that matched one of Spielberg’s own creations?]]>

To make the dromaesaur better match the size of humans in the movie, the creators of

Mosquitoes existed during the age of dinosaurs and can be preserved in amber.
It would not be difficult to bring an animal back to life by using ancient bits of DNA.
Mosquitoes existed during the age of dinosaurs, are preserved in amber, and most likely fed only on dinosaurs.

Cryolophosaurus earned the dinosaur which of the following nicknames?]]>
Cryolophosaurus’s skull. The position of the crest is reminiscent of the front of Elvis Presley’s hair.

Brontosaurus. However, Marsh had already given a name to another skeleton of the same dinosaur in 1877:
According to the international rules by which dinosaurs are named, if two or more identities are given to the same genus or species, then the first published name has priority. Therefore, the dinosaur name
is not valid, and Marsh’s sauropod is instead called
Sauropod heads were lightly constructed with joints that fell apart easily when the dinosaurs decomposed.
Predators would eat the heads off first to prevent the dinosaur from escaping.
Only a thing piece of bone held together the head and neck of sauropods.
The muscles that connected the sauropod's head to its neck deteriorated after the dinosaur died.
These sutures had a tendency to come apart fairly rapidly as a sauropod decayed, leaving the carcass vulnerable to predation (being gnawed and broken or carried away by hungry scavengers) or river currents (it was easy for even small streams to carry away part of a sauropod skull). ]]>
Velociraptor may have had feathers?]]>
