the public for the very first time. this is a skull of a pliosaur, one of the most fearsome predators the planet has ever seen. i think the fossil s incredible. i think it would have been very terrifying, eating a lot of predators. it has big teeth. it s remarkably well preserved and the specimen is almost complete. this is exemplary. this is the best you ll ever see, i think. i can categorically say that. it was the top of the food chain, there s nothing bigger than this. so, it fed on everything. it fed on its own kind. it fed on. anything it could get its teeth into, it d feed on. this gigantic reptile lived 150 million years ago. it would have terrorised the oceans, devouring passing prey with a single bite. the fossil was found halfway down a cliff face in dorset s kimmeridge bay.
