Dinosaurs evolved from other reptiles (socket-toothed archosaurs) during the Triassic period, over 230 million years ago. Dinosaurs evolved soon after the Permian extinction, which was the biggest mass extinction that ever occured on Earth. During this time (the Triassic period), the mammals also evolved.
Where did the dinosaurs come from?
The upshot: The earliest dinosaurs originated and diverged in what is now South America before trekking across the globe more than 220 million years ago when the continents were assembled into one gargantuan landmass called Pangea.
What animals did dinosaurs evolve from?
Dinosaurs are a type of reptile, and they evolved from another group of reptiles called ‘dinosauromorphs’ around 250 million years ago. The dinosauromorphs were small and humble animals, and they didn’t look anything like T. rex or Brontosaurus.
What eventually evolved into dinosaurs?
By the middle of the Triassic about 225 million years ago, sauropsids had evolved into dinosaurs. Dinosaurs became increasingly important throughout the rest of the Mesozoic Era, as they radiated to fill most terrestrial niches. This is why the Mesozoic Era is called the Age of the Dinosaurs.
What animal evolved from the T rex?
Birds evolved from a group of meat-eating dinosaurs called theropods. That’s the same group that Tyrannosaurus rex belonged to, although birds evolved from small theropods, not huge ones like T. rex. The oldest bird fossils are about 150 million years old.
What came before dinosaurs?
The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
What came after dinosaurs?
The good old days. About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.
Are dinosaurs still alive?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.

What was the first animal on earth?
A comb jelly. The evolutionary history of the comb jelly has revealed surprising clues about Earth’s first animal.
How long have humans existed?
While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago.
When did humans first appear on Earth?
They first appeared in the fossil record around 66 million years ago, soon after the Cretaceous–Paleogene extinction event that eliminated about three-quarters of plant and animal species on Earth, including most dinosaurs.
What humans evolved from?
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means ‘upright man’ in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.
Are sharks dinosaurs?
Today’s sharks are descended from relatives that swam alongside dinosaurs in prehistoric times. … It lived just after the dinosaurs, 23 million years ago, and only went extinct 2.6 million years ago.
What did T Rex evolved into?
rex) evolved from tiny dinosaurs, fossils show. The mighty Tyrannosaurus rex used to be very small, and evolved over 20 million years into a massive super predator. Scientists say that newly discovered fossils provide a missing link showing how the dinosaur evolved.
Is a chicken a dinosaur?
So, are chickens dinosaurs? No – the birds are a distinct group of animals, but they did descend from the dinosaurs, and it’s not too much of a twist of facts to call them modern dinosaurs. There are many similarities between the two types of animal, largely to do with bone structure.
