Abstract The ecological context of early vertebrate evolution is envisaged as a long-term trend towards increasingly active food acquisition and enhanced locomotory capabilities culminating in the emergence of jawed vertebrates. However, support for

Placoderms are an extinct group of early jawed vertebrates that play a key role in understanding the evolution of the gnathostome body plan, including the origin of novelties such as jaws, teeth, and pelvic fins. As placoderms have a poorly ossified

Biomechanical insights into the dentition of megatooth sharks (Lamniformes: Otodontidae)

Autor: Antonio Ballell, Humberto G. Ferrón

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-9 (2021)

Abstract The evolution of gigantism in extinct otodontid sharks was paralleled by a series of drastic modifications in their dentition including widening of the crowns, loss of lateral cusplets, and acquisition of serrated cutting edges. These traits

Paired fins are a major innovation that evolved within the jawed vertebrate lineage after divergence from the living jawless vertebrates. Extinct jawless armored stem-gnathostomes exhibit a diversity of paired bodywall extensions, from skeletal proce

Acanthodians are a major group of Paleaozoic jawed vertebrates that constitute a paraphyletic assemblage of stem-chondrichthyans (Brazeau and Friedman, 2015). Representatives of this group are characterized, among other traits, by the presence of bon
