Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.
Lepospondyli is a diverse taxon of early tetrapods.With the exception of one late-surviving lepospondyl from the Late Permian of Morocco (Diplocaulus minimus), [6] lepospondyls lived from the Visean stage of the Early Carboniferous to the Early Permian and were geographically restricted to what is now Europe and North America.
The Sunset Tree is the ninth studio album by the Mountain Goats, released on April 26, 2005 by 4AD.The album's songs revolve around the house John Darnielle grew up in and the people who lived there, including his mother, sister, stepfather, friends, and enemies.
The transition from fins to limbs occurred once an endoskeleton entered the base of the fin, as seen in today's lungfish. [21] This is thought to have originated in the group Sarcopterygians, including osteolipiforms like Eusthenopteron, due to the homology of the tetrapod forelimb and the osteolepiform fin endoskeleton.

Diadectomorpha is a clade of large tetrapods that lived in Euramerica during the Carboniferous and Early Permian periods and in Asia during Late Permian (Wuchiapingian), [1] They have typically been classified as advanced reptiliomorphs (transitional between "amphibians" sensu lato and amniotes) positioned close to, but outside of the clade Amniota, though some recent research has recovered ...

Synapsida [a] is a diverse group of tetrapod vertebrates that includes all mammals and their extinct relatives. It is one of the two major clades of the group Amniota, the other being the more diverse group Sauropsida (which includes all extant reptiles and birds).
Embolomeri is an order of tetrapods or stem-tetrapods, possibly members of Reptiliomorpha.Embolomeres first evolved in the Early Carboniferous (Mississippian) Period and were the largest and most successful predatory tetrapods of the Late Carboniferous (Pennsylvanian) Period.
