Abstract

Based on available information (original studies and published data), a brief review of the structure and morphogenetic features of the exoskeleton of osteostracan agnathan vertebrates (Osteostraci, Vertebrata) is provided. The geometry of vertical cross sections of the cephalothoracic shield in different osteostracan taxa is analyzed.

Keywords:

Osteostraci early vertebrates exoskeleton morphogenesis shield sections
