Who discovered Temnodontosaurus?
Mary Anning
Temnodontosaurus was an ichthyosaur from the early Jurassic, some 196 to 190 million years ago. It was found in England by Mary Anning, and later in Germany. It was, in fact, her first ichthyosaur.
Is Temnodontosaurus a dinosaur?

Are ichthyosaurs dinosaurs?
Marine reptiles, such as ichthyosaurs, plesiosaurs and mosasaurs are not dinosaurs. Nor is Dimetrodon or other reptiles in the same group (previously called ‘mammal-like reptiles’ and now called synapsids). None of these other extinct groups shared the characteristic upright stance of dinosaurs.
How did ichthyosaurs reproduce?
Ichthyosaurs were viviparous; they gave birth in the water to live young (instead of laying eggs, as other reptiles do). This is known because the fossilized bones of baby Ichthysaurs have been found inside the bones of adults.
Why did ichthyosaurs go extinct?
Ichthyosaurs – shark-like marine reptiles from the time of dinosaurs – were driven to extinction by intense climate change and their own failure to evolve quickly enough, according to new research by an international team of scientists.
How big is a ichthyosaur?
The ancient remains of a gigantic marine reptile have been found in southwestern England. Known as an ichthyosaur, the animal lived about 205 million years ago and was up to 85 feet long—almost as big as a blue whale, say the authors of a study describing the fossil published today in PLOS ONE.
Are ichthyosaurs still alive?
This last ichthyosaur genus was thought to have become extinct early in the late Cretaceous, during the Cenomanian about 95 million years ago. The ichthyosaurs thus would have disappeared much earlier than other large Mesozoic reptile groups that generally survived until the end of the Cretaceous.
Did dolphins evolve from ichthyosaurs?
Mesozoic “fish lizards”, ichthyosaurs were marine reptiles that independently became adapted to a life at sea around 200 million years before dolphins.
What did ichthyosaurs evolved from?
terrestrial reptiles
They descended from terrestrial reptiles, conquered the open oceans, became agile hunters of fish and squid, and persisted over incredibly long 155 million years.
Did ichthyosaurs have live births?
Eight fossilized embryos have been discovered in a pregnant ichthyosaur fossil that was first found in 2011, revealing that these reptiles gave birth to live offspring instead of laying eggs.
