What is the largest prehistoric shark?
O. megalodon
O. megalodon was not only the biggest shark in the world, but one of the largest fish ever to exist. Estimates suggest it grew to between 15 and 18 metres in length, three times longer than the largest recorded great white shark.
Did sharks exist before dinosaurs?
A: Sharks were swimming around in the ancient seas 150 million years before the first dinosaurs rumbled about on land. Dinosaurs did not appear on the scene until the Jurassic period, which began about 200 million years ago.
Are hammerhead sharks prehistoric?
The hammerhead ancestor probably lived in the Miocene epoch about 20 million years ago. The team found that two divergent lineages of small sharks about 3 to 4 feet long originated independently at separate times in the past.
What is a dinosaur shark?

What’s bigger Megalodon or whale shark?
The Megalodon has been compared to the whale shark (around 12.65 metres, or close to 41.50 feet) and the scientific community has determined that Megalodon was larger, based on both weight and length. Megalodon was also far bigger than the great white shark, which would only be around half of Megalodon’s size.
Is the frilled shark a dinosaur?
As a marine animal, the frilled shark is a living fossil because of its relatively unchanged anatomy and physique, since first appearing in the primeval seas of the Late Cretaceous (ca. 95 mya) and the Late Jurassic (150 mya) epochs.
Was there a dinosaur shark?
