Carboniferous Tarrasius is an extinct genus of Tarasiiformes.
Tarrasius problematicus (of
Mississippian origin, ~ 350
Ma) featured a fully regionalized
tetrapod-like spine divided into 5 distinct segments. It is not considered a
transitional fossil though, but an extreme example of
convergent evolution. ==See also==
