Did Turtles Live With Dinosaurs? The earliest marine turtles are believed to have appeared during the Jurassic period, but it wasn’t until the Cretaceous period 100 million years ago that sea turtles began to evolve. Prehistoric turtles coexisted with dinosaurs until they went extinct 65 million years ago.
Did turtles exist before dinosaurs? Sea turtles have been around since dinosaurs roamed the earth, more than 100 million years!
Are turtles part of the dinosaur family? Recent studies have shown that turtles belong in the group Archelosauria, along with relatives like birds, crocodiles, and – you guessed it – dinosaurs. Turtles evolved alongside dinosaurs, with sea turtles emerging as a distinct type about 110 million years ago.
What animals alive today lived with dinosaurs? Mammals are common today, but only three monotreme species still exist.
These are the duck-billed platypus and a couple of spiny anteaters, or echidnas.
Many reptile species died during the K-T event, but snakes, lizards and the crocodilians persevered.
Crocodilians have been on the planet for about 240 million years.

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.
Are dinosaurs still alive in 2020?
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
Are Sharks older than dinosaurs?
Shark fossils date back more than 400 million years – that means sharks managed to outlive the dinosaurs, survive mass extinctions, and continue to serve an important role near the top of underwater food chains.

Can dinosaurs come back?
Without access to dinosaur DNA, researchers can’t clone true dinosaurs. New fossils are being uncovered from the ground every day. The cartilage, from the Hypacrosaurus species of the Cretaceous Period, is over 70 million years old but has been calcified and fossilized, which may have protected the inside of the cells.
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.
What was 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.

Are Acanthodii extinct?
Acanthodii (sometimes called spiny sharks) is a class of extinct fishes, having features of both bony fish (Osteichthyes) and cartilaginous fish (Chondrichthyes). They appeared in the early Silurian (430 mya) and lasted until the late Permian (250 mya).
Are Dinosaurs Real?
Dinosaurs are a group of reptiles that have lived on Earth for about 245 million years. In 1842, the English naturalist Sir Richard Owen coined the term Dinosauria, derived from the Greek deinos, meaning “fearfully great,” and sauros, meaning “lizard.” Dinosaur fossils have been found on all seven continents.

Where are dinosaurs now?
Although known for large size, many Mesozoic dinosaurs were human-sized or smaller, and modern birds are generally small in size.
Dinosaurs today inhabit every continent, and fossils show that they had achieved global distribution by at least the Early Jurassic epoch.
