摘要

在中国中三叠世的陆生动物群中，四足类中以坎尼梅里亚目（Kannemeyeriiformes）为主。虽然已收集到丰富的卡尼美耶亚类的材料，但对其颅骨后的形态信息，尤其是幼体的研究并不深入。本文描述了中三叠世二马营地层中的一具有关节的Sinokannemeyeria骨架，并报告了其股骨的组织学显微结构。根据组织学信息，该标本为晚期幼体。该标本首次揭示了Sinokannemeyeria幼体的颅后信息。

The morphology and histology of a juvenile Sinokannemeyeria from the Middle Triassic Ermaying Formation of Shanxi, North China

Kannemeyeriiformes were dominated tetrapods in the Middle Triassic terrestrial faunae of China. Although abundant materials of Sinokannemeyeria have been collected, their postcranial morphology information is not well studied, especially the juveniles. This paper presents a description of an articulated Sinokannemeyeria skeleton from the Middle Triassic Ermaying Formation and reports the histological microstructure of its femur. This specimen represents a late-stage juvenile based on the histological information. For the first time, this specimen offers insights into the postcrania information of juvenile Sinokannemeyeria.
