Description

[edit]

The genus is known from a partial skull preserved in ventral view. The teeth in the upper and lower jaws were fused into tooth plates.[1]

Diet and lifestyle

[edit]

It is likely that Oenosaurus led a durophagous lifestyle as indicated by the broad tooth plates.[1] It is unknown if this animal was aquatic or terrestrial.

Phylogeny

[edit]

It is currently considered to be a sapheosaur.[2]
