Mandibles of rhizodontids: Anatomy, function and evolution within the tetrapod stem-group






Transactions of the Royal Society of Edinburgh Earth Sciences 93(3): 255-279

Mandibles of rhizodontids: Anatomy, function and evolution within the tetrapod stem-group

The Rhizodontida (Pisces: Sarcopterygii) is a clade of predatory fishes from the Upper Devonian (Aztecia; ?Givetian of Antarctica) through to the Upper Carboniferous (Strepsodus; Moscovian of northern Europe and North America). They form the most basal plesion within the tetrapod stem-lineage. The mandibles were dominated by large symphysial tusks on the dentary. Not much else is known of the mandibles in primitive rhizodontids.
