描述
叠瓦蛤具有由垂直于表面沉积的方解石构成的厚壳,未风化的化石外壳通常保有其活着时的珠母光泽。[3]大部分物种具有突出的生长线,呈凸出的半圆,与外壳的边缘同心。[3]
1952年,Inoceramus steenstrupi 的这具长187厘米的巨型标本被发现于奇拉基特克遗址(Qilakitsoq),该化石已有83百万年的历史,源自桑托期至下坎帕期。[4]古生物学家推测,该物种巨大的体型可能源自对于浑浊水底环境的适应,其巨大的体型使其拥有相对较大的鳃部区域,使其能够在较为缺少氧气的环境下生存。[3]
分类
叠瓦蛤科的内部分类存在争议,如Platyceramus属有时被认为属于该属的亚属。该属内的有效物种数量也存在争议。
