Do dinosaurs have periods?
The ‘Age of Dinosaurs’ (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods.
Are dinosaurs male or female?

Scientists worldwide have long debated our ability to identify male and female dinosaurs.
How did at Rex mate?
‘All dinosaurs used the same basic position to mate,’ said Dr Beverly Halstead, an English researcher who was one of the first to tackle the subject. ‘Mounting from the rear, he put his forelimbs on her shoulders, lifting one hind limb across her back and twisting his tail under hers. ‘
Was Sue the T Rex pregnant?
The results confirmed those from the 2005 study, that the T. rex had medullary bone and was likely pregnant when she died, Schweitzer said. “This analysis allows us to determine the gender of this fossil, and gives us a window into the evolution of egg laying in modern birds,” Schweitzer said in a statement.
Can dinosaurs breed in Jurassic world?
In the Jurassic Park novel and the movie it is stated that when genes from the dinosaur genome were lost, the frog-version of those genes were built into the new dinosaurs. In the story, the presence of these frog-genes gave the dinosaurs the ability to switch sexes and reproduce. In reality, this is very unlikely.
What raptors died in Jurassic world?

Did all dinosaurs come from eggs?
All dinosaurs laid eggs, which were fertilized through sexual reproduction between a male and a female. There is evidence that some species of dinosaurs cared for their young during incubation and after hatching.
Are dinosaur eggs like birds’ eggs or reptiles’ eggs?
New fossil egg discoveries show early dinosaurs and marine reptiles laid soft-shell eggs like those of turtles, snakes and lizards and not the hard shells of bird eggs today, according to a new study.
