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.

No, modern reptiles did not evolve from dinosaurs. Modern reptiles and dinosaurs both belong to the group known as archosaurs, but they evolved along separate lineages. Dinosaurs went extinct around 65 million years ago, while modern reptiles, such as snakes, lizards, and turtles, continued to evolve and diversify.

∙ 10y agoNo. Although the basal form of the synapsids, the clade to which all mammals including humans belong, is similar to the basal reptile, sauropsids, the clade to which modern reptiles belong, are in fact a sister clade to synapsids, and not ancestral to mammals.

If dinosaurs didn't have penises how did they procreate?
Most dinosaurs likely reproduced by mating, with the male using a cloaca to transfer sperm to the female's cloaca. This method of reproduction is similar to how modern birds reproduce. While the exact mating behaviors of dinosaurs are still a topic of research and debate, this is the current understanding based on fossil evidence and comparisons to modern relatives.
How long ago did mammals evolve from reptiles?
Mammals evolved from reptiles around 200 million years ago, during the Mesozoic Era. This evolutionary transition led to the development of unique features that distinguish mammals from reptiles, such as hair, mammary glands, and a more advanced brain structure.
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?
No, archaeologists do not study dinosaurs. Paleontologists are the scientists who study dinosaurs and other prehistoric life forms. Archaeologists study human history and artifacts from ancient civilizations.
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 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.
Why did birds evolve after reptiles?
Because they can generate their own body heat - reptiles cannot and need a warm environment
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.
Why do scientists believe that birds evolved from dinosaurs?
Birds are thought to have evolved from bipedal dinosaurs.
