No, although modern reptiles and dinosaurs do share common ancestors that lived in the distant past (likely the Carboniferous epoch). Birds, however, evolved from dinosaurs in the Jurassic epoch.

If dinosaurs didn't have penises how did they procreate?

Remember that dinosaurs were the precursors of birds and they were also reptiles. Birds and amphibians, male and female, have a sexual organ called a cloaca which they would press together to exchange sperm. However, reptiles do have an internal penis, that only appears externally during sex, which would be used with the female's cloaca.


How long ago did mammals evolve from reptiles?

Although reptiles displaying mammal-like characteristics appeared around 300 million years ago, the first true reptiles evolved around 200 million years ago. Although it is not known what the first true mammal was, they are generally believed to have been small and shrew-like.


Why was the discovery of the Archaeopteryx important?

The discovery of Archaeopteryx was important because it provided crucial evidence for the theory of evolution. This fossilized creature had features of both birds and dinosaurs, supporting the idea of a shared evolutionary history between the two groups. Additionally, it showed that birds evolved from theropod dinosaurs, helping to bridge the gap between reptiles and birds in the tree of life.


Do archaeologists study dinosaurs?

Yes, but they choose not to. Archaeologists concern themselves with human and societal development (like anthropologists) and as such they deal with remains that are too young to have fossilized. If an archaeologist wanted to, they certainly could apply their skills to paleontology, but they leave that to the paleontologists just like the paleontologists leave anthropology to archaeologists and anthropologists.


What are good open ended questions about pyramids?

How do you think the ancient Egyptians were able to construct such massive pyramids without modern technology? What significance do you believe pyramids held for ancient Egyptian society, beyond being tombs for pharaohs? In what ways have pyramids inspired modern architecture and design? How do you think our understanding of pyramids and their purpose might evolve in the future with new technological advancements and research methods?

Did dinosaurs evolve into reptiles?

No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.


Did mammals evolve from dinosaurs?

No. Mammals evolved from synapsid reptiles, a group not closely related to dinosaurs. Dinosaurs are more closely related to modern reptiles and birds than they are to mammals.


Did dinosaurs evolve from reptiles?

Yes, dinosaurs did evolve from reptiles. They are part of a group called archosaurs, which also includes modern birds and crocodiles. Dinosaurs evolved from a group of reptiles called archosauriforms during the Triassic period.


Did underwater dinosaurs evolve into crocodiles?

what an interesting topic! Birds and reptiles are the living descendantsof the dinosaurs that survived the meteorite-triggered mass extinction that killed off most of the species living 66 million years ago. And of all reptiles, crocodiles are the most closely related to birds.


What are the differences between dinosaurs and modern reptiles?

There are many differances between the two. Dinosaurs were warmblooded, whereas reptiles are coldblooded. Reptiles also have legs that come out at right angles to their body, and a unusual knee structure. Dinosaurs had leg and hip structures close to that of modern mamals in the case of the herbavores and birds in the case of carnivores.


Did birds evolve from lizards?

No, birds didn't evolve from lizards, but they did evolve from dinosaurs, a different group of reptiles. Dinosaurs are different from lizards especially because of their hip structure. Birds descended from a group of dinosaurs known as theropods (bipedal carnivores)


Why aren't dinosaurs mammals?

Dinosaurs and mammals evolved from two separate branches of reptiles. Mammals evolved from synapisid reptiles (all of which are not extinct) while dinosaurs along with the modern branches of reptiles evolved from sauropsids. So dinosaurs are more closely related to modern reptiles than they are to mammals. In more recent years scientist tend to agree that birds are in fact a surviving branch of dinosaurs.


What year did dinosaurs evolve from reptiles?

Evolution is generally a gradual process, such that it is generally difficult to classify transition species one way or the other. Would you say birds are reptiles? Birds are dinosaurs. Dinosaurs and reptiles share a common ancestor, probably dating to some time in the early Triassic. That would be around 250 million years ago.


How did birds evolve from reptiles?

But they did. Specifically, birds evolved from a subgroup of dinosaurs (which were reptiles) known as theropods. There is a lot of fossil and anatomical evidence for this.


From what dinosaur did cats evolve?

Cats did not evolve from dinosaurs. Cats evolved from a common ancestor of modern carnivores, which lived after the extinction of dinosaurs.


Are dinosaurs ex stinkend?

Yes, all dinosaurs are extinct. But, their modern-day ancestors, reptiles and birds, live on.


Are dinosaurs the oldest mammals?

No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
