Do Protoceratops lay eggs?
But the Protoceratops nest shows some species were still laying soft eggs toward the end of the age of dinosaurs 66 million years ago, even as others evolved to lay hard-shelled eggs.
Did Protoceratops have egg nests?
Protoceratops was probably a herding animal, like some other ceratopsians. This hypothesis is supported by the finding of bone beds, large deposits of bones of the same species in an area, and large groups of nests. Each nest had 12 or more eggs, laid in a spiral fashion.
Is Protoceratops a ceratopsian?
Protoceratops andrewsi is a fairly small and primitive ceratopsian, or horned dinosaur. Although it lacked the horns of later species, Protoceratops had a distinct bump above its nostrils and thickened bone over its eye sockets.
Is Protoceratops a dinosaur?
Protoceratops, (genus Protoceratops), ceratopsian dinosaur found as fossils in the Gobi Desert from 80-million-year-old deposits of the Late Cretaceous Period. Protoceratops was a predecessor of the more familiar horned dinosaurs such as Triceratops.
How did mosasaurs reproduce?
Because of their body structure, researchers had suspected that mosasaurs did not haul themselves out onto a beach to lay eggs, similar to how sea turtles reproduce. Fossilized remains of other prehistoric swimmers, the ichthyosaurs, have been found in the process of giving birth.
What did Protoceratops look like?
Protoceratops was an herbivore from Mongolia. The name comes from the Greek language ‘proto- meaning “first,” and ‘-certaops,’ meaning horn face. It looks like a mini version of Triceratops, with the same distinctive frill on its face.
Did mosasaurs have live birth?
Added to other fossils – such a purportedly pregnant mosasaur that has yet to be formally described and a forerunner of mosasaurs called Carsosaurus found with young inside – the Yale babies suggest that mosasaur mothers gave live birth in open water.
Did T Rex lay eggs?
rex parents cared for their young before or after they hatched. No T. rex eggs or nests have ever been found, but fossils of other Tyrannosaur relatives suggest that they laid elongated eggs, roughly 20 or more at a time.
Has a 72 million year old dinosaur embryo been found?
Unhatched dino nicknamed Baby Yingliang. A 72-million-year-old dinosaur embryo was found in China. The unhatched dino is one of the best preserved fossils of its kind ever found. Scientists say it shows that birds and dinosaurs hatched similarly.
How did the Mosasaurus have babies?
So which form of birth did mosasaurs employ? They could have come ashore to lay eggs but no egg-laying sites had ever been discovered. Because these baby mosasaur fossils were found in the open ocean where egg-laying is not possible, the circumstances suggest that mosasaurs may have been viviparous.
Did Protoceratops have quills?
Did you know that while some artists choose to depict Protoceratops with long, porcupine-like quills on its tail, there is no direct evidence of quills on this dinosaur? These reconstructions are inspired by the early ceratopsian Psittacosaurus, which did have quills.
Is Protoceratops the ancestor of Triceratops?
Other researchers immediately noted the importance of the Protoceratops finds, and the genus was hailed as the “long-sought ancestor of Triceratops”.
How Do dinosaurs Get Pregnant?
Dinosaurs must have had sex to reproduce. As in nearly all modern-day reptiles, males would have deposited sperm inside females, which would later lay fertilized eggs containing developing dinosaur embryos.
