pliosaurs in general were relatively speedy swimmers, with well-muscled flippers on both ends of their trunks,but it would have been a very powerful swimmer similar to whales of today.there were several reasons why this animal went extinct. First of all,Mosasaurs came in this time and competed with Pliosaurus for its main food source – fish.Second, water temperatures began to change during this time and Pliosaurus may not have been able to adapt quickly enough.Which is probably why this animal went extinct at the end of the Jurassic (145 million years ago).
