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. Her brother found the skull, and she found the rest of the skeleton, in about 1810. It was described in 1814. There are four or five species of "Temnodontosaurus". They grew to killer whale size, about 30 to 40 feet.
