The Mongolepidida: Scale structure and systematic position
Abstract
The scale structure of four genera of the Mongolepidida from the Upper Llandovery of Central Asia is described. Anumber of characters, such as lamelline in odontodes, absence of neck canal in odontodes, mode of crown and base growth, and canal system in scales, suggest that the Mongolepidida is an independant group of lower vertebrates, related to the Chondrichthyes.
