Dinosaurs evolved from more primitive reptiles, very much like lizards. The evolutionary step that made them so successful was putting their legs directly underneath their bodies so they could stand upright with the stability of bones rather that with the strength of muscles. This allowed them to put on more weight than would have been possible for a land-dwelling animal with limbs at its sides, as with the lizards and frogs.
Dinosaurs evolved from reptiles during the Triassic period, about 230 million years ago. They are thought to have descended from Archosaurs, a group of reptiles that also gave rise to crocodiles and birds.

Did apes evolve from dinosaurs?
No, apes did not evolve from dinosaurs. Apes belong to a different evolutionary line known as the hominids, which diverged from the lineage of dinosaurs millions of years ago. Dinosaurs became extinct around 65 million years ago, while apes evolved later, branching off from a shared ancestor with monkeys around 25 million years ago.
Is it possible the asteroid that destroyed the dinosaurs has any connection with the existence of humans?
It is possible that the asteroid impact that led to the extinction of the dinosaurs created conditions that allowed mammals, including early human ancestors, to thrive and evolve. The elimination of dominant dinosaur species may have opened up ecological niches that mammals were then able to occupy and evolve into various forms, eventually leading to the emergence of humans.
What was the positive result of the dinosaur extinction?
The extinction of dinosaurs allowed mammals to diversify and evolve, eventually leading to the rise of mammals as the dominant terrestrial animals. This extinction event also paved the way for the evolution of new species and ecosystems to emerge.
What will probably be without the dinosaurs extinct?
If the dinosaurs had not gone extinct, it is likely that many species that evolved after their extinction would not exist today, as they would have to compete with dinosaurs for resources. The extinction of dinosaurs opened up ecological niches that allowed for the evolution of new species which may not have been possible if the dinosaurs were still around.
Is the dinosaurs ALL wiped out when the large meteorite hit the earth?
No, not all dinosaurs were wiped out by the large meteorite impact that occurred about 66 million years ago. Some small dinosaurs, birds, and other species managed to survive and evolve into the diverse range of species we see today.
Did dinosaurs evolve into reptiles?
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
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)
When did the piranha first evolve?
in the dinosaurs epoch
When did dinosaurs evolve?
Dinosaurs evolved 225 million years ago in the Late Triassic.
Did any dinosaurs live in the Cambrian Era?
No. In the Bambrian Era, dinosaurs had yet to evolve.
Did primates evolve before dinosaurs became extinct?
no
Why did the dinosaurs evolved?
They didn't evolve! They went extinct.
Did birds ever evolve to dinosaurs?
No. It's the other way around. A branch of the dinosaurs evolved into birds.
Where elephants here before dinosaurs?
Mammals did not evolve until dinosaurs were prolific when they did appear they were very small and very scarce when dinosaurs died out.
Did horses develop during the last days of the dinosaurs?
No, horses did not evolve alongside dinosaurs. The earliest horses evolved shortly after the extinction of non-avian dinosaurs.
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.
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.
