Plesiosaurs
Plesiosaurs were creatures with flippers, long necks and a small head. They were all reptiles and many think they had pups/calves in the water, like whales, dolphins, etc. do today.
Plesiosaurs breathed air through nostrils and would have had to surface for air, like whales, dolphins, etc do today. Some think that, with their long necks, they could swim in the water and have their nostrils and/or head out of the water to breathe. No proof for this theory has stepped forward.
As far as can be gathered, it seems plesiosaurs had a smooth skin like a dolphin or a seal instead of scales like most reptiles. Perhaps plesiosaurs were covered in blubber to to keep themselves warm, we just won’t know until we see a live one.
Pliosaurs
These creatures were short-necked and had gigantic heads compared to the small-headed plesiosaur. In fact, some pliosaurs, like Kronosaurus, had heads 1/3 of their total body size; can you imagine that?
Some pliosaurs, like Lipleurodon had specialized skulls that had the same design as sharks. This design was a link between the roof of its mouth and the nostrils. With this link a Lipleurodon could “smell” under water and be able to find prey easy.
Pliosaurs and Plesiosaurs
Both of these creatures were made by God on the fifth day and I’m totally excited to learn more about them. You can expect to read some amazing things as I send out profiles on the dragons of the seas.
