Exceptional preservation of organs in Devonian placoderms from the Gogo lagerstätte

Science, 2022
The origin and early diversification of jawed vertebrates involved major changes to skeletal and soft anatomy. Skeletal transformations can be examined directly by studying fossil stem gnathostomes; however, preservation of soft anatomy is rare.

Placoderms (Armored Fish): Dominant Vertebrates of the Devonian Period

Annual Review of Earth and Planetary Sciences, 2010
Placoderms, the most diverse group of Devonian fishes, were globally distributed in all habitable freshwater and marine environments, like teleost fishes in the modern fauna.

Pelvic and reproductive structures in placoderms (stem gnathostomes)

Biological Reviews, 2015
ABSTRACTNewly discovered pelvic and reproductive structures within placoderms, representing some of the most crownward members of the gnathostome stem group and the most basal jawed vertebrates, challenge established ideas on the origin of the pelvic girdle and reproductive complexity.

Copulation in antiarch placoderms and the origin of gnathostome internal fertilization [PDF]

Nature, 2014
Reproduction in jawed vertebrates (gnathostomes) involves either external or internal fertilization. It is commonly argued that internal fertilization can evolve from external, but not the reverse. Male copulatory claspers are present in certain placoderms, fossil jawed vertebrates retrieved as a paraphyletic segment of the gnathostome stem group in ...
