Edops Craigi
''Edops'' ('swollen face') is an extinct genus of temnospondyl amphibian from the Late Carboniferous - Early Permian periods. Unlike more advanced temnospondyls of the time, such as ''Eryops'', ''Edops'' exhibited an archaic pattern of palatal bones, and still possessed various additional bones at the back of the skull. Edopoids also had particularly big premaxillae (the bones that form the tip of the snout) and proportionally small external nostrils. Within the clade, the most basal member seems to be ''Edops'' from the Early Permian Archer City Formation of the US, a broad-skulled animal with large palatal teeth. ''Edops'' was fairly big, at in length. Fragmentary remains from the Viséan of Scotland appear to come from ''Edops'' or a close relative and hence predate the type ''Edops'' material of the Permian. Discovery and naming The American paleontologist Alfred Sherwood Romer named ''Edops'' "swollen face" (from Greek ''oidos'' "swelling" and Greek ''ops'' "face") in 19 ...

Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession.

Edopoidea
Edopoidea is a clade of primitive temnospondyl amphibians including the genus ''Edops'' and the family Cochleosauridae. Edopoids are known from the Late Carboniferous and Early Permian of North America and Europe, and the Late Permian of Africa. They are among the most basal temnospondyls, and possess a number of primitive features that were lost in later members of the group. Description Edopoids are relatively large temnospondyls, with many species estimated to have grown several meters in length. The skull of ''Edops'' is broad while those of cochleosaurids are narrower and elongated. Distinguishing features of edopoids include the presence of an intertemporal bone that is absent in all other temnospondyls, and the lack of a pineal foramen, a small hole on the skull roof of many early tetrapods (young individuals still possess this hole). Relative to other temnospondyls, edopoids also have enlarged premaxillae, maxillae, and nasal bones in the snout region, which constrict t ...

Prehistoric Amphibian Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian Temnospondyls Of North America
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chenoprosopus Lewisi
''Chenoprosopus'' is a genus of extinct cochleosauridae that lived during late Carboniferous and early Permian periods.Reisz, R.R. (2005). "A New Skull of the Cochleosaurid Amphibian Chenoprosopus (Amphibia: Temnospondyli) from the Early Permian of New Mexico". ''New Mexico Museum of Natural History and Science Bulletin No. 30'' Two known species of ''Chenoprosopus'' are ''C. milleri'' and ''C. lewisi. Chenoprosopus lewisi'' was described in the basis of a virtually complete skull with maximum skull length of 95 mm. It is significantly smaller than ''Chenoprosopus milleri'' and was differentiated from that taxon by Hook (1993) based on sutural patterns of the skull roof. Hook also mentioned the reduced size of the vomerine tusks differentiated ''C. lewisi'' from ''C. milleri,'' but the different size of these tusks may be different ontogenetic stages of growth. Many of other cochleosaurids from the same time period have an elongated vomer and wide and elongate choana. However ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cochleosaurus Florensis
''Cochleosaurus'' (“spoon lizard”, from the Latin ''cochlear'' "spoon" and Greek ''sauros'' “lizard”) were medium-sized edopoid temnospondyls that lived in Euramerica during the Moscovian age. Two species, ''C. bohemicus'' and ''C. florensis'', have been identified from the fossil record. Both species lived in equatorial saltwater marshes with highly variable water depth. The majority of ''Cochleosaurus'' remains have been discovered in fossil assemblages in the Late Carboniferous Sydney Coalfield in Nova Scotia and the Kladno Formation in the Czech Republic. History The first ''Cochleosaurus'' specimen to be discovered was excavated by Antonín Jan Frič in the Westphalian D fossil deposits in Nýřany, Czech Republic, in1879. Due to the incomplete skeleton, he believed it to be a new species of '' Melosaurus'', which he named ''Melosaurus bohemicus''. After more detailed analysis in 1885, Frič realized the specimens belonged to a new genus, and renamed the species ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochleosaurinae
Cochleosauridae is a family of edopoid temnospondyl amphibians, among the most basal of temnospondyls. Most members of this family are known from the late Carboniferous (Pennsylvanian) and early Permian (Cisuralian) of Europe and North America, though ''Nigerpeton'' is known from the Late Permian (Lopingian) of Niger in North Africa.

Adamanterpeton Ohioensis
''Adamanterpeton (''from Greek: Αδάμαντας ''adamantas,'' meaning 'diamond' and Greek: ἑρπετόν ''herpetón'', meaning 'creeping thing') is a genus of Edopoid Temnospondyl within the family Cochleosauridae. The type species ''A. ohioensis'' was named in 1998 and is currently the only known species within this genus. ''Adamanterpeton'' is rare in the Linton vertebrate assemblage, with other amphibians like ''Sauropleura'', ''Ophiderpeton'', and '' Colosteus'' being more common. Unlike other Linton vertebrates, ''Adamanterpeton'' may have been adapted to a terrestrial lifestyle. History and Discovery The species is only known from two specimens in the fossil record. The cochleosaurid specimens were discovered in the fossil-rich Allegheny Formation of Linton, Ohio by John Strong Newberry, but were only formally described and figured by Edward Drinker Cope in 1875. Using Cope's (1875) work, Moodie (1916) attributed the specimens to '' Macrerpeton'' ''huxleyi,'' howev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
