The question of how tetrapod limbs evolved from fins is one of the great puzzles of
evolutionary biology. While palaeontologists, developmental biologists, and geneticists have …

Mandibular teeth and dentitions are features of jawed vertebrates that were first acquired by
the Palaeozoic ancestors,–of living chondrichthyans and osteichthyans. The fossil record …

The evolutionary history of osteichthyans (bony fishes plus tetrapods) extends back to the
Ludlow epoch of the Silurian period. However, these Silurian forms have been documented …

The discovery of Entelognathus revealed the presence of maxilla, premaxilla, and dentary,
supposedly diagnostic osteichthyan bones, in a Silurian placoderm. However, the …

Late Devonian, that is from the Givetian to Famennian stages about 385–365 million years …

The transition from fishes to tetrapods was one of the most dramatic events in the evolution
of vertebrates, but many pivotal fossils are incomplete, resulting in gaps in the data that are …
