Mystriosuchus is an extinct genus of phytosaur (similar to modern day crocodiles) that lived during the Late Triassic in Europe. It grew to about 13 feet long and weighed up to 1,000 lbs. Morphological examinations indicate Mystriosuchus was adapted to aquatic life and had a fish diet, some species being freshwater while others were marine.






Mesosaurus, an extinct reptile from the Permian Period was one of the first marine reptiles and inhabited fresh waters of Africa and South America supporting the theory of continental drift.






Geosaurus, "Earth lizard", is an extinct marine crocodile that lived in the ocean during the late Jurassic to the early Cretaceous. Geosaurus had curved teeth for slashing captured prey.






Rhynchosaurus, Masdodonsaurus, Hyperodapedon, Telerpeton

Rhynchosaurus (beaked lizard) is a genus of rhynchosaur that lived during the Middle Triassic Period

Mastodonsaurus ("breast tooth lizard") was a large-headed amphibian of the Triassic. It was a giant among the stegocephalians and the largest animal 200 million years ago. It looked like a huge frog, with a triangular head that was about 4 feet long and with total body length about 15 feet long. Mastodonsaurus inhabited swampy pools and lived mainly on fish.

Hyperodapedon was a beaked reptile from the late Triassic. Fossils have been found in several continents, due to the continents being joined together during the Triassic.

Tulerpeton lived mainly in shallow marine water in Devonian times and is one of the first true tetrapods to have arisen. Tetrapods are vertebrate animals having four limbs. Amphibians, sauropsids and mammals are tetrapods.






Actinodon, Ceraterpeton, Dilichosoma, Loxomma

Actinodon was an amphibious carnivore which lived during the Permian.

Remains of Ceraterpeton of the Permian are found only in the "Coal Forests" of Buxieres les Mines in France.

Dilichosoma, renamed Phlegethontia, were legless, burrowing, one meter long, snake-like amphibians of the Carboniferous and Permian periods in Europe and North America.

Loxomma is an extinct genus of large crocodile-like reptiles named Loxommatidae. They were large aquatic predators of the Carboniferous period. Their long rows of needle-like teeth show that they were fish-eaters.
