Dunkleosteus terrelli, an arthrodire placoderm, is one of the most widely recognized fossil
vertebrates due to its large size and status as one of the earliest vertebrate apex predators …

Background The size of Dunkleosteus and other late Devonian arthrodire placoderms has
been a persistent problem in paleontology. The bony head and thoracic armor of these …

Dunkleosteus is a widely-recognized prehistoric organism, yet its life appearance,
paleobiology, and even basic morphology remain poorly understood. A new reconstruction …

Two pachyosteomorph arthrodires are described from the Upper Devonian of North
America, Dunkleosteus raveri sp. nov. and Dunkleosteus amblyodoratus sp. nov.(from the …

Our knowledge about the body morphology of many extinct early vertebrates is very limited,
especially in regard to their post-thoracic region. The prompt disarticulation of the dermo …

Cenomanian mesoeucrocodylians from North America are known primarily from isolated
teeth and scutes; any associated remains of this age are noteworthy and represent welcome …

A collection of 58 specimens of Dolloidraco longedorsalis from the southwestern Ross Sea
was studied for intraspecific variation in the number of second dorsal and anal rays, number …

Biomechanical models illustrate how the principles of physics and physiology determine
function in organisms, allowing ecological inferences and functional predictions to be based …

Northwest Territories, Canada, provide a unique perspective on early jawed fish
morphology. Three of the putative chondrichthyans were previously known from only …

ABSTRACT The Cleveland Member (Late Famennian) fish fauna represents one of the most
speciose and well-collected faunas from the Late Devonian; however, our understanding of …
