Ancient Seas Basilosaurus Photo from  Earth Archives Kingdom: Animalia Class: Mammalia Conservation Status: Extinct (EX) Era: Late Eocene (40-33.9 million years ago) WHAT WAS IT? The name would suggest that this creature was a dinosaur, an ancient lizard. But that was a mis-classification when first discovered in the US. Further fossil discoveries and study into the creature determined that this was in fact a mammal and a whale. It is even believed to be on the evolutionary line for modern dolphins. The Basilosaurus is one of the largest creatures to have existed in the time after the mass extinction event which wiped out the dinosaurs. It was 18-20m (59-66ft) long, which means it was not the largest sea creature to have ever lived but it is up there! It had a long, eel-like body and small hind limbs. Being only 35cm (11 inches) and made of three fused tarsals (or digits), these hind limbs did not have much function. With limited movement, it is pos...

Ancient Seas #1 Megalodon Photo from Sharkipedia The megalodon was probably the largest predator to have ever lived - we haven't found one bigger yet. It is larger than the whale shark. Their teeth were over twice the size of great white's teeth. Recent discoveries of megalodon nurseries have led scientists to believe they gave birth in shallow waters. Ancient Seas #2 Sarcosuchus Photo from IMDb Its name, Sarcosuchus, means fleshy crocodile. It was twelve feet longer than modern saltwater crocodile. Their home became the Sahara desert. Ancient Seas #3 Plesiosaurus   Photo from ThoughtCo It is postulated that they laid their eggs upon land like the sea turtle. Their teeth were designed to catch prey, not chew. They swallowed their prey whole. Their long necks were supported by 40 vertebrae. Ancient Seas #4 Hybodus Photo from ThoughtCo The hybodus shark species survived on the planet ten times longer than the av...

Liyvatan or Leviathan Melvelli Artistic Rendering from Scary Nature's YouTube Kingdom: Animalia Class: Mammalia Conservation Status: Extinct (EX) Found: Peru Era: Miocene Lived: 11-12 million years ago Diet: Smaller whales Weight: 57 tonnes* Size: 13.5 - 17.5m (44 - 57ft)* Habitat: Unknown *These are estimates, without living specimens or more remains it is nearly impossible to know. The leviathan melvelli or Livyatan was a toothed whale which lived around 12 million years ago during the Miocene era. It is the largest known extinct whale, which grew up to 17.5m (57ft). This is still smaller than the Blue Whale which lives today but it would have ruled the seas all those years ago, with evidence of it being a fierce hunter. Its remains were found in Peru, an area which would have been under the sea at the time making it rife with marine fossils. Colossal teeth had been found in 2008, but it wasn't until 2010 when more of this whale w...
