Orthomerus

Orthomerus (meaning "straight femur") is a genus of dubious hadrosaurid dinosaur from the Late Cretaceous of the Netherlands. It is today an obscure genus, but in the past was conflated with the much better known Telmatosaurus.

==Discovery and history== thumb|left|Orthomerus dolloi fossils The type species Orthomerus dolloi was in 1883 named by the well-known British paleontologist Harry Govier Seeley. The genus name is derived from the Greek ὀρθός (orthos), "straight", and μηρός (meros), "thigh". The specific name honours the French/Belgian paleontologist Louis Dollo, who had identified the bones in August 1882, during a visit to London.
