Nothosaurs (superfamily Nothosauroidea) were Triassic marine sauropterygian reptiles. They averaged about 3 metres (10 ft) in length, with a long body and tail.[1] The feet were paddle-like, and are known to have been webbed in life, to help power the animal when swimming.[2] The neck was quite long, and the head was elongated and flattened, and relatively small in relation to the body. The margins of the long jaws were equipped with numerous sharp outward-pointing teeth, indicating a diet of fish and squid.
