Are sharks the oldest creature on earth?
Fish that were alive during the Age of Enlightenment are still swimming strong.
A Greenland shark has lived at least 272 years, making the species the longest-lived vertebrate in the world – smashing the previous record held by a 211-year-old bowhead whale.
But it may have been as old as 500 years..
What killed the Megalodon?
A new study suggests that a tsunami of cosmic energy from a supernova killed off large ocean animals – including the huge megalodon shark – 2.6 million years ago. A shower of particles may have spelled curtains for the megalodon, a school-bus-sized shark, 2.6 million years ago.
Are sharks living dinosaurs?
Sharks. … 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.
How old is the Megalodon?
The earliest megalodon fossils (Otodus megalodon, previously known as Carcharodon or Carcharocles megalodon) date to 20 million years ago. For the next 13 million years the enormous shark dominated the oceans until becoming extinct just 3.6 million years ago.
What are the big 5 mass extinctions?
Top Five ExtinctionsOrdovician-silurian Extinction: 440 million years ago. Small marine organisms died out.Devonian Extinction: 365 million years ago. … Permian-triassic Extinction: 250 million years ago. … Triassic-jurassic Extinction: 210 million years ago. … Cretaceous-tertiary Extinction: 65 Million Years Ago.
Who was the last dinosaur to die?
adult triceratopsThe discovery adds to growing evidence that the dinosaurs were wiped out when a comet or asteroid crashed into Earth at the end of the cretaceous. The animal, most likely an adult triceratops, was not the last dinosaur standing, but the last survivor of their impressive reign to be identified by palaeontologists.
What is the oldest species still alive today?
horseshoe crabAlthough it can be hard to tell exactly how old some species are and scientists are confident that they still haven’t uncovered nearly all the fossils that could be found, most scientists agree that the oldest living species still around today is the horseshoe crab.
What was the first land animal on earth?
newmani is the earliest body fossil of a millipede, and has been dated to 428 million years ago (late Wenlock epoch to early Ludlow epoch). The earliest centipedes follow some 10 million years later, and the first known vertebrate on land, Tiktaalik, is 50 million years younger than Pneumodesmus.

Did dinosaurs live on Pangea?
Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.
Are Sharks older than dinosaurs?
As a group, sharks have been around for at least 420 million years, meaning they have survived four of the “big five” mass extinctions. That makes them older than humanity, older than Mount Everest, older than dinosaurs, older even than trees. It is possible that sharks just got lucky in the lottery of life.
How old are sharks as a species?
450 million yearsWhen did sharks first appear? The earliest fossil evidence for sharks or their ancestors are a few scales dating to 450 million years ago, during the Late Ordovician Period. Emma Bernard, a curator of fossil fish at the Museum, says, ‘Shark-like scales from the Late Ordovician have been found, but no teeth.
What’s the first animal on earth?
comb jellyA comb jelly. The evolutionary history of the comb jelly has revealed surprising clues about Earth’s first animal.
What animals are still evolving?

Which dinosaurs are still alive today?
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.
