Metriorhynchus was a Thalattosuchian, which was a group of extinct primitive sea crocodilians. It lived in the late Jurassic Period
It was seen in the beginning of the first movie, chasing a small amphibian and attempting to eat it, but fails and swims away. The Metriorhynchus resembles more of a fish; in reality thalattosuchians resembled crocodiles but with a fish-like tail and fins. It was the first Belly Dragger, however, it is the only fully aquatic one.
- Metriorhynchus is one of the few Sharpteeth that Littlefoot and friends have never come face to face with. Other Sharpteeth include Hydrotherosaurus, Dromaeosaurus, Mosasaurus, Postosuchus, Erythrosuchus, Nothosaurus, Kronosaurus, and Acrocanthosaurus (as only Chomper saw this species, not the others).
- Though being a certain type of Crocodilian, which is termed Belly Dragger. it's unknown if this term would be used since the Metriorhynchus is not well adapted to land rather than living in the sea. If the characters were to ever encounter it, it would probably be categorized as a Swimming Sharptooth.
