Keraterpetontidae
The Diplocaulidae ("double cauls") is an extinct family of "nectridean" tetrapodomorphs that arose during the Late Carboniferous and died out in the Late Permian. 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.

Tetrapodomorph Families
Tetrapodomorpha (also known as Choanata) is a clade of vertebrates consisting of tetrapods (four-limbed vertebrates) and their closest sarcopterygian relatives that are more closely related to living tetrapods than to living lungfish. Advanced forms transitional between fish and the early labyrinthodonts, such as ''Tiktaalik'', have been referred to as "fishapods" by their discoverers, being half-fish, half-tetrapods, in appearance and limb morphology. The Tetrapodomorpha contains the crown group tetrapods (the last common ancestor of living tetrapods and all of its descendants) and several groups of early stem tetrapods, which includes several groups of related lobe-finned fishes, collectively known as the osteolepiforms. The Tetrapodomorpha minus the crown group Tetrapoda are the stem Tetrapoda, a paraphyletic unit encompassing the fish to tetrapod transition. Characteristics Among the characteristics defining tetrapodomorphs are modifications to the fins, notably a humerus wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplocaulus Minimus
''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. Remains attributed to ''Diplocaulus'' have been found from the Late Permian of Morocco and represent the youngest-known occurrence of a lepospondyl. Description ''Diplocaulus'' had a stocky, salamander-like body, but was relatively large, reaching up to in length. Although a complete tail is unknown for the genus, a nearly complete articulated skeleton described in 1917 preserved a row of tail vertebrae near the head. This was construed as circumstantial evidence for a long, thin tail capable of reaching the head if the animal was curled up. Most studies since this discovery have argued that anguiliform (eel-like) tail movement was the main force of locomotion utilized by ''D ...

Diploceraspis
''Diploceraspis'' is a genus of diplocaulid nectrideans. It lived in North America during the Permian period. It closely resembles its relative, '' Diplocaulus''. It generally sports the same features as ''Diplocaulus'', though it was smaller, measuring over 46 cm. Beerbower originally recognised two species, ''D. burkei'' and ''D. conemaughensis'', but they are no longer regarded as being distinct from one another as their size ranges were found to overlap. Other species include ''D. meritae'' from Nebraska and an indeterminate species from Oklahoma.

It has coastlines on the Mediterranean Sea to the north and the Atlantic Ocean to the west, and has land borders with Algeria to Algeria–Morocc ... may be of this genus.
