Diplocaulus (meaning "double stalk") is an extinct genus of lepospondyl amphibians which lived from the Late Carboniferous to the Late Permian of North America and Africa. Diplocaulus is by far the largest and best-known of the lepospondyls, characterized by a distinctive boomerang -shaped skull .
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 Diplocaulidae ("double cauls") is an extinct family of "nectridean" tetrapodomorphs that arose during the Late Carboniferous and died out in the Late Permian. [1] They are distinguished by the presence of strange, horn-like protrusions jutting out from the rear of their skulls; in some genera said protrusions gave their heads an almost boomerang-like outline.
Microsaurs are known from Europe and North America. Microsaur remains have been found from Europe and North America in Late Carboniferous and Early Permian localities. Most North American microsaurs have been found in the United States in Arizona, [8] Texas, Oklahoma, Ohio, [9] Illinois, as well as Kansas and Nebraska, [10] although remains have also been found in Nova Scotia.

The Reptile Database is a scientific database that collects taxonomic information on all living reptile species (i.e. no fossil species such as dinosaurs).The database focuses on species (as opposed to higher ranks such as families) and has entries for all currently recognized ~14,000 species and their subspecies, [1] although there is usually a lag time of up to a few months before newly ...

Instead, they consistute an evolutionary grade (a paraphyletic group), ancestral to living tetrapods such as lissamphibians (modern amphibians) and amniotes (reptiles, mammals, and kin). "Labyrinthodont"-grade vertebrates evolved from lobe-finned fishes in the Devonian , though a formal boundary between fish and amphibian is difficult to define ...
