Bothriolepidoidei
Bothriolepidoidei is a suborder of antiarch placoderm fishes. The group is considered paraphyletic. Taxonomy The cladogram is taken from Bothriolepid antiarchs (Vertebrata, Placodermi) from the Devonian of the north-western part of the East European Platform. {{Clade, style={{Clade , label1= Bothriolepidoidei , 1={{Clade , 1={{Clade , 1='' Microbrachius'' , 2='' Wudinolepis'' , 2={{Clade , 1={{Clade , 1=''Dianolepis'' , 2=''Jiangxilepis'' , 3='' Kirgisolepis'' , 4='' Tenizolepis'' , 2={{Clade , 1=''Monarolepis'' , 2={{Clade , 1='' Bothriolepis'' , 2=''Grossilepis Antiarchi ("opposite anus") is an order of heavily armored placoderms.

Antiarchi
Antiarchi ("opposite anus") is an order of heavily armored placoderms. The antiarchs form the second-most successful group of placoderms after the arthrodires in terms of numbers of species and range of environments. The order's name was coined by Edward Drinker Cope, who, when examining some fossils that he thought were armored tunicates related to '' Chelysoma'', mistakenly thought that the orbital fenestra (i.e., the hole in the headshield for the eyes, nose and pineal foramen) was the opening for the mouth, or oral siphon, and that the opening for the anal siphon was on the other side of the body, as opposed to having both oral and anal siphons together at one end. The front portions of their bodies were heavily armored, to the point of literally resembling a box with eyes, with the sometimes scaled, sometimes naked rear portions often becoming sinuous, particularly with later forms. The pair of pectoral fins were modified into a pair of caliper-like, or arthropod-like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
