Identification of Iguanodon and Maiasaura

Asked by: Dennis Hartung

The easiest way to distinguish iguanodon from maiasaura is to look for iguanodon’s hands, which are very peculiar indeed. The hand has five digits. The thumb has a large, prominent spike on it for defensive purposes. The three middle fingers are fused and end in hoof-like nails for walking on all fours.

What are the characteristics of a Iguanodon?

What does a Maiasaura look like?

Maiasaura were large, attaining a maximum known length of about 9 metres (30 ft). They had a flat beak typical of hadrosaurids, and thick noses. They had a small, spiky crest in front of the eyes. This crest may have been used in headbutting contests between males during the breeding season.
