Did all dinosaurs come from eggs?

How much is a dinosaur egg worth?
Besides that, the determination of the fossil's value depends upon its condition, rarity, and age as well. Although the common value exists of a dinosaur egg is about $400 to $1500.
How did plesiosaurs reproduce?
Plesiosaurs were reptiles, which as a group tend to lay eggs rather than giving birth. ... Other prehistoric marine reptiles were known to be exceptions to that rule, but until now fossil evidence that plesiosaurs did the same has been frustratingly elusive.

rex's puny, undersized arms. According to Steven Stanley, a paleontologist at the University of Hawaii at Manoa, T. rex arms were used to slash prey in close proximity to the dinosaur. ... And the short arm length was actually more beneficial for slashing, considering the size of T.
How did T Rex have babies?
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.

"This says they may well have been warm-blooded and, if so, we can't think of them as slow, lumbering reptiles any more." His results are published today in the journal PLoS ONE.
How do I know if I have dinosaur eggs?
Genuine fossil eggs usually have an easily identifiable shell which differs significantly from the enclosed sediments either by having a fine surface ornamentation (the smoother the "shell," the less likely it is to be a non-bird dinosaur egg) or a specific type of crystalline structure in cross-section.
Where are dinosaur eggs found?
Sand dunes: Many dinosaur eggs have been recovered from sandstone deposits that formed in the ancient dune fields of what are now northern China and Mongolia. The presence of Oviraptor preserved in their life brooding position suggests that the eggs, nests, and parents may have been rapidly buried by sandstorms.
What is the largest dinosaur egg?
Hatching prehistoric parenting habits. A discovery nearly 25 years in the making, paleontologists have published their scientific findings on the largest dinosaur eggs ever discovered. Measuring roughly half-a-metre in length each, the eggs were collected by a farmer in China roughly 30 years ago.
Was there a dinosaur born in China?
The oviraptorosaur fossil was uncovered from rocks that are 70 million years old in Ganzhou City, China, the Carnegie Museum of Natural History (CMNH) said in a news release in January.
