Ichthyosaurus


Ichthyosaurus
Although technically not a true ‘dinosaur’, Ichthyosaurus, or ‘fish lizard’, filled the same niche in Earth’s oceans and was one of the most dominant marine species of the Mesozoic era (252-65.5 Ma) Resembling today’s dolphins, Ichthyosaurus measured in at roughly two metres (6.6 feet) in length and was capable of cruising through the water at around 40 kilometres (25 miles) per hour, enabling it to catch fish and squid with ease. The fact that Ichthyosaurus had a very large pair of eyes protected by a pair of bony, structural- supporting rings has led some palaeontologists to believe  the species frequently hunted at great depths where pressure was very high.
