Two acmes of the genus Crioceratites were recorded in the current Crioceratites loryi Zone (lower Hauterivian) in the Lower Cretaceous series of south-eastern France (Vocontian Basin), both in the classic section of the Cheiron ravine (Castellane area) and in the Hauterivian GSSP area at La Charce. The revision of an abundant material allows us to define Crioceratites claveli sp. nov. The first acme and the first part of the second acme correspond to the range of C. claveli sp. nov. and not to C. loryi as previously admitted. The remaining of the second acme is related to this latter species solely. The great abundance of C. claveli sp. nov. in the lower interval Horizon allowed a detailed analysis of its variation around 3 factors: (1) dimorphism; (2) multipolar variation of order two here characterized by an absence of correlation between the ornamental and morphological shell parameters (non-covariant factors); and (3) ontogenic heterochronies, which depend on the robustness of the ornamentation only. On the other hand, the northern edge of the Provençal platform delivered C. jurensis (revised here) from the top part of the Acanthodiscus radiatus Zone, which reduces the gap with the older Crioceratites known in the uppermost Valanginian. Finally, the study of the stratigraphic distribution of C. claveli sp. nov. and C. loryi leads to propose the new C. claveli (Sub)Zone instead of the C. loryi (Sub)Zone. This proposal for the south-eastern France may have extension potential for the Mediterranean Province of the Mediterranean Caucasian Subrealm (Tethyan Realm).

属的两个Acme的Crioceratites被记录在当前Crioceratites loryi区（降低欧特里夫）的下白垩统法国东南部（Vocontian盆地）的，无论是在谢龙山沟（卡斯特兰区）的经典部分，并在欧特里夫La Charce 的 GSSP 区域。丰富材料的修订使我们能够定义Crioceratites claveli sp。十一月 第一个顶点和第二个顶点的第一部分对应于C. claveli sp的范围。十一月 而不是像先前承认的那样对C. loryi。第二个顶点的其余部分仅与后一个物种有关。大量的C. clavelisp. 十一月 在较低的区间 Horizo​​n 允许详细分析其围绕 3 个因素的变化：（1）二态性；(2) 这里二阶多极变异的特征是装饰和形态外壳参数（非协变因子）之间没有相关性；(3) 个体异时性，这仅取决于纹饰的坚固性。另一方面，普罗旺斯平台的北边缘从Acanthodiscus radiatus区的顶部提供了C. jurensis（此处修订），这减少了与最上层 Valanginian 中已知的较旧Crioceratites的差距。最后，研究了C. claveli sp.的地层分布。十一月 和C. loryi导致提出新的C. claveli (Sub)Zone 而不是C. loryi (Sub)Zone。这项针对法国东南部的提案可能具有扩展地中海高加索亚域（Tethyan Realm）的地中海省的潜力。
