10 Terrifying Prehistoric Sea Monsters:\r
Some of the largest creatures this world has ever seen lived millions of years ago. Here are ten of the largest, most fearsome sea monsters ever to prowl the oceans:\r
\r
10-Shastasaurus: The ichthyosaurs were marine predators that looked like modern dolphins, and could reach a massive size during the Triassic period over 200 million years ago. Shastasaurus, the largest marine reptile species ever found, was a variety of ichthyosaur that could grow to over 65 feet (20m).\r
9-Dakosaurus: Dakosaurus could reach a length of 16 feet (5m). Its unique teeth have led scientists to consider it an apex predator during its reign of terror. Dakosaurus was first discovered in Germany and, with its odd reptilian-yet-fishy body, was one of the top predators in the sea during the Jurassic period.\r
8-Thalassomedon: Thalassomedon was a species of Pliosaur whose name translates from Greek to sea lord -- and for good reason. They were massive predators, reaching lengths of up to 40 feet (12m). Its flippers were nearly 7 feet (2m) long, allowing it to swim the depths with deadly efficiency.\r
7-Nothosaurus: They were armed with a mouth full of sharp, outward-pointing teeth, suggesting a diet of squid and fish.Fossil evidence suggests that they lived during the Triassic period over 200 million years ago.\r
6-Tylosaurus: Tylosaurus was a species of Mosasaur. It was enormous, reaching more than 50 feet (15m) in length. They lived during the late Cretaceous in the seas that covered North America, where they sat firmly atop the marine food chain for several million years.\r
5-Thalattoarchon Saurophagis: Only recently discovered, T. saurophagis was the size of a school bus, reaching nearly 30 feet (9m) long. It is an early species of ichthyosaur that lived during the Triassic period, 244 million years ago.\r
4-Tanystropheus: Tanystropheus was a reptile that could reach 20 feet (6m) long, and it is thought to have been alive during the Triassic period nearly 215 million years ago.\r
3-Liopleurodon: Liopleurodon was a marine reptile measuring in at more than 20 (6m) feet in length. It mostly lived in the seas that covered Europe during the Jurassic period, and it was one of the top predators around.\r
2-Mosasaurus: Fossil evidence suggests that Mosasaurus could reach as much as 50 feet (15m) in length, making it one of the largest marine predators of the Cretaceous period. \r
1-Megalodon: Megalodons prowled the depths during the Cenozoic Era, 28 -- 1.5 million years ago, and were a much bigger version of the great white shark, an apex predator of todays oceans. But while our great whites only reach a maximum length of 20 feet (6m), Megolodons could grow to 65 feet in length (20m).\r

Sea monsters are sea-dwelling mythical or legendary creatures, often believed to be of immense size. Marine monsters can take many forms, including sea dragons, sea serpents, or multi-armed beasts. They can be slimy or scaly and are often pictured threatening ships or spouting jets of water. The definition of a monster is subjective, and some sea monsters may have been based on scientifically accepted creatures such as whales and types of giant and colossal squid.\r
