List Of Thelodont Genera

	List Of Thelodont Genera This list of thelodonts is an attempt to create a comprehensive listing of all Genus, genera from the Fossil, fossil record that have ever been considered to be members of the Class (biology), class Thelodonti. This list excludes purely vernacular terms. It includes (almost) all commonly accepted genera, but also genera that are now considered invalid, doubtful (''nomen dubium, nomina dubia''), or were not formally published (''nomen nudum, nomina nuda''), as well as synonym (zoology), junior synonyms of more established names, and genera that are no longer considered thelodonts. This list includes 67 generic names.

picture info	Genus Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

picture info	Cephalopterus (thelodont) Umbrellabird is the common name referring to three species of birds in the genus ''Cephalopterus''. They are named for their distinct umbrella-like hoods. The umbrellabird was described by Sir Alfred Wallace, a companion of Charles Darwin, in the 1800s while on an expedition to South America. Umbrellabirds face habitat loss, and two of the three species are at risk of extinction. Basic Information Umbrellabirds can be found in the rainforests of Central and South America. They are generally solitary, but known to co-inhabit areas with other birds including other umbrellabirds, and similar species such as woodpeckers. With a total length of , it is among the largest members of the cotinga family, and the male Amazonian umbrellabird is the largest passerine in South America. The typical weight of an umbrellabird ranges from 320 to 570 g (.77 to 1.26 lbs), with a wingspan reaching about 66 to 71 cm (26 to 28 in). Umbrellabirds are thought to live for an average of 16 years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Furcacauda ''Furcacauda'' is a genus of thelodontid agnathan from the Lower Devonian of Canada Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by tot ..., and is the type genus of the order Furcacaudiformes. Furcacaudiform thelodontids were deep water jawless vertebrates with symmetrical fork and lobed-finned tails and scales smaller than typical loganellid and nikoliviid thelodonti scales. Furcacaudiform thelodonts are noted as having a laterally compressed body, large anterior eyes, slightly posterior, lateral, and vertical to a small mouth, and a condensed curved row of branchial openings (gills) directly posterior to the eyes. Many but not all had laterally paired fins. Wilson and Caldwell also note the presence of a caudal peduncle and a long caudal fin made of two large lobes, one dorsal and ...

Morphology ''Drepanolepis'' possessed a tall, angelfish-like body, with a ventral mouth and a hypocercal tail. The gill atrium is large for this order, and the nasal runs down to the oral cavity from the orbit. The oral cavity is jawless, with no premaxilla or maxilla present.
