What dinosaur is related to a shark?
Pay a visit to these living fossils Our shysharks are members of an even older family of sharks, that has survived relatively unchanged for over 150 million years – outliving the dinosaurs and the fearsome Ginsu shark! Want to see more ancient animals? You won’t believe how sea turtles evolved…
Where Did sharks come from?
Most scientists believe that sharks came into existence around 400 million years ago. That’s 200 million years before the dinosaurs! It’s thought that they descended from a small leaf-shaped fish that had no eyes, fins or bones. These fish then evolved into the 2 main groups of fish seen today.
How are sharks and dinosaurs different from each other?
Sharks come from fish ancestry that is different than dinosaur heritage. It’s suggested that all life comes from marine life, but the difference is sharks come from a line of cartilagenous fish whereas the dinosaurs come from bony fish instead. Are sharks primitive?
Where did the first shark teeth come from?
The earliest shark-like teeth we have come from an Early Devonian (410-million-year-old) fossil belonging to an ancient fish called Doliodus problematicus. Described as the ‘least shark-like shark’, it is thought to have risen from within a group of fish known as acanthodians or spiny sharks.

What kind of shark was in the Mesozoic era?
The Sharks of the Mesozoic Era. Perhaps the most surprising shark from the Cretaceous period is the recently discovered Ptychodus, a 30-foot-long monster whose numerous, flat teeth were adapted to grinding up tiny mollusks, rather than large fish or aquatic reptiles.
When was the first shark found on Earth?
To understand how modern sharks adapted and evolved, we first have to look back through the fossil record of their ancestors. Originating from a time before dinosaurs walked the earth, the earliest shark scales date back about 425 million years, and the earliest shark teeth are from the Devonian Period, about 410 million years ago.
Which is older a shark or a dinosaur?
Sharks are older than dinosaurs. They’ve stood the test of time and are almost exactly the same as they were all those millions of years ago. It begs the question: why haven’t sharks evolved? Sharks have evolved, it just doesn’t really seem like it. Sharks have no known predators so they dominate their ocean landscape.
How did sharks and crocodiles evolve from dinosaurs?
Just like crocodiles, sharks did not evolve from dinosaurs. They’re all completely different species from each other, evolving in different ways. Around 65 million years ago, scientists believe a giant meteor came and struck the earth in the Gulf of Mexico.
