A nearly complete skeleton was found in 1973. This showed it was a member of the long-tailed sub-order of pterosaurs, the [[Rhamphorhynchoidea]]. ''Eudimorphodon'' was small in size, with 110 teeth packed into a jaw only 6 cms long. Teeth at the front are fangs, further back the teeth are small and multipointed, many with five cusps. This is [[wikt:unique|unique]] among pterosaurs, whose teeth are usually of a simple [[cone|conical]] form.<ref>Wellnhofer P. 1991. ''The illustrated encyclopedia of pterosaurs''. London, UK: Salamander Books. p67 {{ISBN|0-86101-566-5}}.</ref> [[Stomach]] contents showed it had eaten a small fish, ''Parapholidophorus''. The top and bottom teeth of ''Eudimorphodon'' came into direct contact with each other when the jaws were closed, especially at the back of the jaw. The teeth were multi-cusped, and [[tooth]] wear shows that ''Eudimorphodon'' was able to crush or chew its food to some degree. Wear along the sides of these teeth suggests that ''Eudimorphodon'' also fed on hard-shelled [[invertebrate]]s. Juvenile ''Eudimorphodon'' had somewhat different and fewer teeth, and may have eaten [[insect]]s. An unsolved puzzle is the flexibility of the [[tail]], which lacks the very long stiffening [[vertebra]]l extensions other long-
