Teleostomi
Clade of jawed vertebrates / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Teleostomi?
Summarize this article for a 10 year old
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. Key characters of this group include an operculum and a single pair of respiratory openings, features which were lost or modified in some later representatives. The teleostomes include all jawed vertebrates except the chondrichthyans and the extinct class Placodermi.

Recent studies indicate that Osteichthyes evolved from placoderms like Entelognathus, while acanthodians are more closely related to modern chondrichthyes. Teleostomi, therefore, is not a valid, natural clade, but a paraphyletic group of species.[1]
The clade Teleostomi should not be confused with the similar-sounding infraclass Teleostei.
