Eupelor
''Eupelor'' is a dubious genus of prehistoric amphibian belonging to the temnospondyl family Metoposauridae. Fossils have been found in present-day Pennsylvania, within the Newark Supergroup, dating to the Late Triassic (Norian). Taxonomy The ''Eupelor'' type species, ''E. durus'', was named ''Mastodonsaurus durus'' by Edward Drinker Cope in 1866 on the basis of AMNH 3927, a number of clavicles and the tooth AMNH 2333 (which could have belonged to a different temnospondyl apart from ''Eupelor''), from the Lockatong Formation (Phoenixville Tunnel site) of Phoenixville, Pennsylvania. In 1868 Cope allocated the species to its own genus, ''Eupelor'', based on differences from ''Metoposaurus'' (then known as ''Metopias''). Colbert and Imbrie (1956) reviewed all Triassic metoposaurids and concluded that ''Eupelor'' should be used for all metoposaurids from North America, especially ''Koskinonodon ''Anaschisma'' ("ripped up") is an extinct genus of large temnospondyls.

Anaschisma
''Anaschisma'' ("ripped up") is an extinct genus of large temnospondyls. These animals were part of the family called Metoposauridae, which filled the crocodile-like predatory Ecological niche, niches in the late Triassic. It had a large skull about long, and possibly reached long. It was an ambush hunter, snapping up anything small enough to fit in its huge jaws. It was very common during the Late Triassic (Carnian-Norian age) in what is now the American Southwest. History of discovery ''Anaschisma'' was erected by Branson (1905) from two metoposaurid skulls from the Popo Agie Formation (Carnian) of Wyoming. The generic name ''Anaschisma'' ("ripped up") was not explained but would derive from Ancient Greek ἀνασχίζω [anaskhizo] "rip up, rend", likely alluding to the fragmented state of the original fossils noted by Branson: "The skulls were in a hard matrix of arenaceous shale, and had been broken in many pieces." The type species, ''A. browni'', was coined for the sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
