软骨鱼类（鲨鱼、鳐和银鲛）的软骨内骨骼表现出复杂的钙化组织排列和形态，这些钙化组织随年龄、物种、摄食行为和在体内的位置而变化。由于缺乏统一的术语，对这些组织类型的发展、进化历史和功能的理解受到阻碍。为了促进相互照明不同领域之间的融合利益，我们提出了组织水平，其中晶体取向/大小界定了三种钙化类型（乳晕，球状和棱柱形），在两种不同的骨骼类型，椎骨和棋盘格软骨相互作用。镶嵌骨骼由覆盖未矿化软骨核心的钙化软骨（棱柱形和球形）的小块（镶嵌物）组成，而脊椎软骨通常包含所有三种类型的钙化。(c)2006年Elsevier GmbH。All rights reserved.
The cartilaginous endoskeleton of chondrichthyan fishes (sharks, rays, and chimaeras) exhibits complex arrangements and morphologies of calcified tissues that vary with age, species, feeding behavior, and location in the body. Understanding of the development, evolutionary history and function of these tissue types has been hampered by the lack of a unifying terminology. In order to facilitate reciprocal illumination between disparate fields with convergent interests, we present levels of organization in which crystal orientation/size delimits three calcification types (areolar, globular, and prismatic) that interact in two distinct skeletal types, vertebral and tessellated cartilage. The tessellated skeleton is composed of small blocks (tesserae) of calcified cartilage (both prismatic and globular) overlying a core of unmineralized cartilage, while vertebral cartilage usually contains all three types of calcification.
