Sarcopterygii (/ ˌ s ɑːr k ɒ p t ə ˈ r ɪ dʒ i. aɪ /; from Ancient Greek σάρξ (sárx) 'flesh' and πτέρυξ (ptérux) 'wing, fin') — sometimes considered synonymous with Crossopterygii (from Ancient Greek κροσσός (krossós) 'fringe') — is a clade (traditionally a class or subclass) of vertebrate animals which includes a group of bony fish commonly referred to as lobe ...
Eusthenopteron (from Greek: εὖ eû, 'good', Greek: σθένος sthénos, 'strength', and Greek: πτερόν pteron 'wing' or 'fin') [2] is a genus of prehistoric sarcopterygian (often called "lobe-finned") fish known from several species that lived during the Late Devonian period, about 385 million years ago. It has attained an iconic ...
Coelacanth. Coelacanths (/ ˈsiːləkænθ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2][3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
List of sarcopterygian genera. This list of lobe-finned fish is a comprehensive listing of all genera that have ever been included in the class Sarcopterygii, excluding purely vernacular terms and Tetrapods. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ( nomen dubium ), or were not ...
Tiktaalik. Tiktaalik (/ tɪkˈtɑːlɪk /; Inuktitut ᑎᒃᑖᓕᒃ [tiktaːlik]) is a monospecific genus of extinct sarcopterygian (lobe-finned fish) from the Late Devonian Period, about 375 Mya (million years ago), having many features akin to those of tetrapods (four-legged animals). [1]
Vorobyeva, 1960. †P. rhombolepis Gross, 1941. Panderichthys is a genus of extinct sarcopterygian (lobe-finned fish) from the late Devonian period, about 380 Mya. Panderichthys, which was recovered from Frasnian (early Late Devonian) deposits in Latvia, is represented by two species. P. stolbovi is known only from some snout fragments and an ...
Cladistic classification of Sarcopterygii is the classication of Sarcopterygii as a clade containing not only the lobe-finned fishes (coelacanths and lungfish) but also the tetrapods, which are closely related to lungfish. The taxon Sarcopterygii was traditionally classified as a paraphyletic group considered either a class or a subclass of ...
Styloichthys. Styloichthys (Greek: stylo "pillar" and ichthys "fish"; "Pillar fish") is a prehistoric sarcopterygian, lobe-finned fish which lived during the Early Devonian (Lochkovian) period of East Yunnan, South China. Because it is clear that the jaws and skull of Styloichthys share many derived features with coelacanthiformes [1] it is ...
