| - | The '''crurotarsians''' are a group of [[Archosauria|archosaur]] reptiles; they are, by definition, all forms closer to crocodiles than to birds. Their main feature is the distinct scute armour; it has, however, been lost in some marine crocodilians and phytosaurs. | + | The '''crurotarsians''' are a group of [[Archosauria|archosaur]] reptiles; they are, by definition, all forms closer to crocodiles than to birds.

| - | During most of the Mesozoic, the first three orders of crurotarsians dominated land ecosystems; however, towards the Cretaceous period crocodilians rised in dominance, although a few members from the other groups still hanged on to life. At the K-T event, nearly all crurotarsians were eliminated, with the exception of semi-aquatic crocodilians. | + | In addition, the bird-like [[Ornithoidea|ornithoideans]] evolved from early crocodilians. |
