Abstract

A study of the diversity of sculpture and histological structure of the exoskeleton in various osteostracan taxa (Osteostraci, Agnatha) enabled the first characterization of the main elements (geometric modules) of the planar organization of the complex relief on their armor surface. The armor relief was analyzed using a circular model of the formation of exoskeletal hard structures. The model was applied to unique material, fragments of a shield of the osteostracan Oeselaspis pustulata (Patten, 1931) from the Silurian of the Severnaya Zemlya Archipelago (Russia).

早期脊椎动物外骨骼浮雕形成的平面几何图案（Osteostraci，Agnatha）

摘要

对各种osteostracan 类群（Osteostraci，Agnatha）中外骨骼的雕塑多样性和组织学结构的研究，首次表征了其装甲表面复杂浮雕的平面组织的主要元素（几何模块）。使用外骨骼硬结构形成的圆形模型分析装甲浮雕。该模型应用于独特的材料，即来自 Severnaya Zemlya 群岛（俄罗斯）志留纪的Oeselaspis pustulata（Patten，1931 年）的盾牌碎片。
