Baryonyx — size comparison — facts and sources
Baryonyx was a large bipedal Early Cretaceous predator associated with rivers and floodplains. It had an elongated crocodile-like snout, nostrils set back from the tip and teeth more rounded in cross-section than those of many theropods. An enormous curved claw occurred on the hand.
Snout anatomy suggests catching fish, and material around the abdomen of the Surrey skeleton provides direct clues: fish scales and Iguanodon bones were found there. Its diet therefore included different animals. The claw may have helped obtain food along the shore, although its exact use is unknown.
William Walker found the first claw fragment in an English clay pit in 1983. Excavations revealed much of the skeleton, improving knowledge of spinosaurids previously represented by far more limited material.
