摘要

摘要描述了产于Shakhtau珊瑚礁群（南西乌拉尔山脉）的阿塞勒和萨克玛碳酸盐岩中的三个Arceodomus属物种（A. praepermica (Fredericks, 1915), A. colvae (Fredericks, 1915), and A. fredericksi sp. nov.）。详细讨论了复杂的至少两层贝壳的结构，并对其功能形态进行了分析。此外，还描述了笛鲷的肌肉疤痕，并提出了对其的解释。根据几个形态特征的组合，提出了一个新科 Arceodomidae fam.

Taxonomical Diversity and Morphology of Rostroconch Shells of the Family Arceodomidae fam. nov. from the Early Permian Shakhtau Reef Massif (Mollusca; Southern Cis-Urals)

Abstract

Three species of the genus Arceodomus (A. praepermica (Fredericks, 1915), A. colvae (Fredericks, 1915), and A. fredericksi sp. nov.) described from the Asselian and Sakmarian carbonates of the Shakhtau reef massif (Southern Cis-Urals). The architecture of complex, at least two-layered shells is discussed in detailed and refined and their functional morphology is analyzed. Muscle scars of Arceodomus are described and their interpretation are proposed. A new family Arceodomidae fam. nov. is proposed in the order Conocardiida for the placement of the genus Arceodomus based on the combination of several morphological characters.

期刊介绍： Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
