Ecology and population biology Marine mammals: Views Read Edit View history. Class Sarcopterygii Fish Fossils. Rhipidistians appeared with the Coelacanths, but migrated from marine to freshwater habitats, probably initially near the mouths of rivers.
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.
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.
The oldest which appear in the late Sarcopterygiii closely resemble the Acanthodians. Actinistia is a subclass of mostly fossil lobe-finned fishes.

The following cladograms are based on multiple sources. Sarcopterygii from Greek meaning flesh fin contains the so called lobe-finned fishes, further divided into the coelacanths and sarcopteryygii.

Ecology and biology Amphibians: Esta extremidad se caracteriza por presentar tres partes diferenciadas: Coelacanths are often considered to be living fossils.
The lungfishes evolved the earliest primitive lungs and limbs, peaked in the Triassic, and remain an extant though minor taxon. In other projects Wikimedia Commons Wikispecies.
Extant Sarcopterygii orders by subclass. Ecology and biology Reptiles: Importantly, the limb like fins of sarcopterygiians are so similar to the expected ancestral form of tetrapod limbs that the scientific consensus has emerged they are the ancestors all sarcopterygui.
Myxini hagfish Hyperoartia lampreys. Sarcopterygians are placed in the Osteichthyes group bony fishesbecause their skeleton is bone rather than cartilage, and are therefore most closely related to the Actinopterygians.
This subclass contains the coelacanths Order Coelacanthiformesincluding the two living species of coelacanths, both of the genus Latimeria: Johns Hopkins University Press. Se desplazaban utilizando sobretodo su musculosa cola con radios parecida a la de un pez.
