Crushing and eating hard prey (durophagy) is mechanically demanding. The cartilage jaws of durophagous stingrays are known to be reinforced relative to non-durophagous relatives, with a thickened external cortex of mineralized blocks (tesserae), rein

Restudy of Campyloprion annectans Eastman, 1902 from North America demonstrated that neither specimen included is diagnostic at the species level; thus, the species name is a nomen dubium. Since this species was designated as the type species of the

The histology and crystallite arrangement of the surface hard tissues in the dermal scales of selected lower actinopterygians, both recent and extinct, as well as several acanthodian genera, were compared, together with the tissue of the collar regio

All three Ordovician agnathans from Canon City, Colorado, USA, possess dentine and an enamel or enameloidcovering layer. Two have extensive bony trabeculae of aspidin below the tubercles, as part of the tesserae, whereas the other has cellular bone o

The origin of fin mesenchyme and the cells forming the distal fin ray skeleton in fishes is unknown, but is often assumed to be the neural crest. To test this possibility, a series of experiments have been done using a vital cell marking technique to

The histology and morphology of Youngolepis, Powichthys, and Diabolepis are reviewed. Four characters are chosen to support the sister-group relationship between Youngolepis and Powichthys, independent from the characters shared by both genera and ot
