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 ...
Coelacanths are a part of the clade Sarcopterygii, or the lobe-finned fishes. They share membership in this clade with lungfish and tetrapods. Externally, several characteristics distinguish coelacanths from other lobe-finned fish. They possess a three-lobed caudal fin, also called a trilobate fin or a diphycercal tail. A secondary tail ...
Sarcopterygii (includes tetrapods) Teleostomi (from Greek τελεος, complete + Greek στόμα, mouth) is an obsolete taxon [ 1 ] of jawed vertebrates that supposedly includes the tetrapods , bony fish , and the wholly extinct acanthodian fish.
Sarcopterygii Euteleostomi ( Eu- teleostomi [ a ] , where Eu- comes from Greek εὖ 'well, good' [ b ] or Euteleostomes , also known as "bony vertebrates " [ c ] ) is a successful clade that includes more than 90% of the living species of vertebrates.
Clade Sarcopterygii (lobe finned fishes, ancestors of tetrapods) The above scheme is the one most commonly encountered in non-specialist and general works. Many of the above groups are paraphyletic, in that they have given rise to successive groups: Agnatha are ancestral to Placodermi, who again have given rise to Osteichthyes, as well as to ...
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 formally published ( nomen nudum ...
a-, an-: Pronunciation: /ə/, /a/, /ən/, /an/. Origin: Ancient Greek: ἀ-, ἀν-(a, an-). Meaning: a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that ...
Kenichthys was a small tetrapodomorph, with a skull about 2 centimetres (0.79 in) long. [3] While only areas of the front of the body are known, it seems likely that Kenichthys would have been similar in general body form to other basal sarcopterygians, with two dorsal fins, paired pectoral and pelvic fins and an anal fin.
