These prehistoric marine reptiles advanced lengthy necks by including extra vertebrae


Hundreds of thousands of years in the past, as dinosaur giants had been stomping round on land, different big reptiles had been dominating the oceans — and a few of them, like plesiosaurs and comparable animals, grew  extraordinarily lengthy, snake-like necks.

Now, scientists have found how a few of these early marine reptiles advanced these prolonged necks moderately rapidly —  by including new vertebrae to their spines.
