Abstract To date, 37 species and 2 subspecies (36 species plus 1 species that with 2 subspecies) of the ostracode genus Cribroconcha Cooper, 1941 have been reported worldwide, ranging in age from the Middle Devonian to the Early Permian with an acme during the Carboniferous. Based on the geographical distribution and morphological characteristics of Cribroconcha, two evolutionary lineages (i.e., Lineage 1 and Lineage 2) are identified, which originated in the European and the Kazakhstan plates, respectively. Lineage 1 can be subdivided into three types: 1-A (stable type), 1-B (reshaped type) and 1-C (spiny type). Lineage 2 has a simpler pattern of evolution compared to Lineage 1. Although there were certain accompanying changes in the morphology of carapaces, the general pattern and most successful evolutionary novelty of Cribroconcha appears to be the appearance of spiny forms in the Early Carboniferous, which continued to be preserved until the Early Permian. The habitats of Cribroconcha may have changed from shallow, warm waters to deep, calm and colder waters in the basinal environments. Four Cribroconcha biozones, extending from the Givetian Stage to Serpukhovian Stage are established in the Euramerica plate, namely C. beckmanni Zone, C. triquetra triquetra Zone, C. cooperi Zone and C. caneyensis Zone.

古生代晚期古生态变化与 Cribroconcha 属 (Ostracoda, Crustacea) 的进化

摘要 迄今为止，世界范围内已报道了 1941 年的 ostracode 属 Cribroconcha Cooper 37 种和 2 个亚种（36 个种加 1 个亚种，2 个亚种），年龄从中泥盆世到早二叠世，在石炭纪达到顶峰。 . 根据Cribroconcha的地理分布和形态特征，确定了两个进化谱系（即谱系1和谱系2），分别起源于欧洲和哈萨克斯坦板块。血统1可以细分为三种类型：1-A（稳定型）、1-B（重塑型）和1-C（多刺型）。与世系 1 相比，世系 2 具有更简单的进化模式。 尽管甲壳的形态有一定的伴随变化，Cribroconcha 的一般模式和最成功的进化新颖性似乎是早石炭世多刺形态的出现，这种形态一直持续到早二叠世。Cribroconcha 的栖息地可能已经从浅水、温暖的水域变成了盆地环境中深、平静和较冷的水域。欧美洲板块形成了从吉维天阶到塞尔普霍维阶的四个 Cribroconcha 生物带，即 C. beckmanni 带、C. triquetra triquetra 带、C. cooperi 带和 C.caneyensis 带。
