Today’s sharks are descended from relatives that swam alongside dinosaurs in prehistoric times. In fact, the largest predator of all time was a shark called a Megalodon. It lived just after the dinosaurs, 23 million years ago, and only went extinct 2.6 million years ago.
Were there sharks during dinosaurs?
Sharks were certainly tenacious. The creatures that thrived during this period survived right into the Cretaceous, often defined by its end. Sixty-five million years ago most of the dinosaurs were wiped out. Many other animals died too but sharks lived on.
Did Sharks survive the asteroid?
Fossil teeth show that the asteroid strike at the end of the Cretaceous killed off many of the largest species of shark. Only the smallest and deep-water species that fed primarily on fish survived.
How many mass extinctions have sharks survived?
Sharks are the consummate survivors. They’ve been around for more than 400 million years, surviving all five of the major mass extinctions in Earth’s history.
Which came first sharks or dinosaurs?
Sharks are among Earth’s most ancient creatures. First evolving over 455 million years ago, sharks are far more ancient than the first dinosaurs, insects, mammals or even trees.
What dinosaurs still exist today?
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 killed the Megalodon?
Extinction of a mega shark
The cooling of the planet may have contributed to the extinction of the megalodon in a number of ways. As the adult sharks were dependent on tropical waters, the drop in ocean temperatures likely resulted in a significant loss of habitat.
Who survived the Great Dying?
The end-Permian extinction event was disastrous for a wide range of organisms on land and in the sea, with as many as 70 percent of terrestrial and 81 percent of marine species dying off.

What is the oldest species of shark?
The Greenland shark is the oldest known shark in the world. The shark’s longevity was only recently discovered in 2016 when a group of scientists analyzed 28 female Greenland sharks. They determined that the Greenland sharks were at least 272 years old, but may potentially be over 500 years old.
Is the Megalodon still alive?
Megalodon is NOT alive today, it went extinct around 3.5 million years ago.

When was the first shark attack?
The first occurred on July 1, 1916. Charles Vansant, a 24-year-old Philadelphia man, went for a late-afternoon swim beyond the breaking waves, The Record reported two days later. Beachgoers reportedly saw the dorsal fin but were unable to alert Vansant before the shark attacked.
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.
