Abstract

Analysis of data on the hard cover structure in various osteostracan taxa (Osteostraci, Agnatha) allowed us to describe geometric patterns of the armor relief formation during morphogenesis of the Vertebrate external skeleton. A circular model of the formation of exoskeletal surface relief has been proposed. A mechanism providing a complete set of the exoskeleton sculpture types was shown to exist already since early Vertebrates.

摘要

对各种骨甲鱼分类群(骨甲亚纲,无颌类)硬壳结构数据的分析,使我们能够描述脊椎动物外骨骼形态发生过程中盔甲纹饰形成的几何模式。已提出外骨骼表面纹饰形成的圆形模型。结果表明,早在早期脊椎动物中就已存在一种能产生全套外骨骼雕刻类型的机制。
