Timeline of genera
[edit]
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.[5][6] It is not considered a transitional fossil though, but an extreme example of convergent evolution.
