Human effects and interactions Marine mammals: The lungfishes evolved the earliest primitive lungs and limbs, peaked in the Triassic, and remain an extant though minor taxon.

Coelacanths are often considered to be living fossils.

They were believed to have gone extinct at the end of the Cretaceous, until the genus Latimeria was discovered off the east coast of South Africa in ; since then, other Latimeria have been discovered in Kenya, Mozambique, Tanzania, Madagascar, and South Africa.

Actinistia is a subclass of mostly fossil lobe-finned fishes. Rhipidistia is now understood to be an ancestor for the whole of Superclass Tetrapoda. Se desplazaban utilizando sobretodo su musculosa cola con radios parecida a la de un pez. Sarcopterygii from Greek meaning flesh fin contains the so called lobe-finned fishes, further divided into the coelacanths and lungfish.

Esta extremidad se caracteriza por presentar tres partes diferenciadas: Tyler Keillor y Beth Rooney. Lobe-finned fish Living fossils Live-bearing fish Ovoviviparous fish Extant Devonian first appearances Vertebrate subclasses.

The Ckase lineage split into two major groups, lungfishes and tetrapodomorphs.

Ecology and biology Reptiles: This subclass contains the coelacanths Order Coelacanthiformesincluding the two living species of coelacanths, both of the genus Latimeria: Sarcopterygians are placed in the Osteichthyes group bony fishesbecause their skeleton is bone rather than cartilage, and are therefore most closely related sarocpterygii the Actinopterygians. Tetrapods comprise amphibians, reptiles, dinosaurs, birds, and mammals and even snakes by descent, the groups that would go on to dominate the land, and result in the appearance humans very, very recently.

The oldest which appear in the late Silurian closely resemble the Acanthodians.
