Daily Dino Fact: Big, flippered awesomesaurs

Mauisaurus
Mauisaurus – The longest sea reptile

Q: What was the biggest of all the swimmers ? -Optimas

A: This question was actually answered back in October, but thought it would be a great refresher. The first point I’d like to make is that the main “swimmers” of the Mesozoic were called plesiosaurs (they were not dinosaurs). They were big, flippered sea reptiles like Liopleurodon. Although, to be sure, the Mesozoic had a rich abundance of sea life! These guys were just the biggest ones.

The Mesozoic was populated with a whole host of incredible sea reptiles that terrorized everything else in the sea. We’ve talked about Liopleurodon before, who was the largest of them all but the longest is actually Mauisaurus.

Like Liopleurodon, Mauisaurus was a plesiosaur. Mauisaurus measured out to be a whopping 65ft (20m) in length and was the longest sea reptile of them all. Found only in New Zealand fossil beds, Mauisaurus must have been a fearsome predator during its day. They’ve even found a fossil of one fighting a mosasaur!

Daily Dino Fact: Plesiosaurs rockin’ the long neck

Q: How long were plesiosaur necks? -Horntrio

A: Good question! Keep in mind that there were many many different kinds of plesiosaurs that ranged from 13ft (4m) to the biggest, the pliosaurs, at 50ft (15m). While we think of plesiosaurs as having long necks, they varied quite a bit. One of the more famous plesiosaurs (a pliosaur) was liopleurodon. He was absolutely giant but had a short little neck that kind of looked like an alligator.

One of the longest plesiosaurs was elasmosaurus, who probably had the biggest neck of them all. Elasmosaurus’ neck was half the length of his body, meaning it was around 23 ft (7m) long! Not quite the same as sauropods, with mamenchisaurus having a neck twice that length but man, thats a really long neck!!
