Strabopida
Strabopidae is the only Family (biology), family of the order Strabopida, an extinct group of arthropods known from the Cambrian period. The order Strabopida contains three valid genera and one doubtful, ''Khankaspis'', ''Paleomerus'', ''Parapaleomerus'' and ''Strabops'', all assigned in the family Strabopidae. Previously, it also contained the genera ''Caryon'', ''Lemoneites'' and ''Neostrabops'', but after a study, they were reassigned as a trilobite, a Glyptocystitida, glyptocystitid echinoderm and a cheloniellid arthropod, respectively. Paleomeridae was also previously included as a family, but after the discovery of a fourth ''Paleomerus'' Biological specimen, specimen and its study, Paleomeridae was synonymized into Strabopidae. Although often suggested to be closely related to Aglaspidida, aglaspidids due to their similar morphology, their exact phylogenetic placement is uncertain due to the poor preservation of all known strabopids. A 2013 attempt to place them in a phylo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleomerus
''Paleomerus'' is a genus of strabopid, a group of extinct arthropods. It has been found in deposits from the Cambrian period (geology), period (Atdabanian Epoch (geology), epoch). It is classified in the Family (biology), family Strabopidae of the monotypic Order (biology), order Strabopida. It contains two species, ''P. hamiltoni'' from Sweden and ''P. makowskii'' from Poland. The generic name is composed by the Ancient Greek words παλαιός (''palaiós''), meaning "ancient", and μέρος (''méros''), meaning "part" (and therefore, "ancient part"). ''Paleomerus'' is one of the oldest arthropods, being sometimes interpreted as the model of the first arachnomorphs. It is part of the order Strabopida, a poorly known group closely related to the aglaspidids of uncertain affinities, often being ignored by researchers and authors due to the poor preservation and abundance of their fossils. It has been suggested that ''Paleomerus'' and the closely related ''Strabops'' could be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
