小舌形贝属（学名：Lingulella）是圆货贝科下已灭绝的一个属，生存在寒武纪至泥盆纪的海洋中，属于较早期的腕足动物，行沙底掘穴或附生于伊尔东钵等浮游生物的方式生活。本属化石广见于世界各地寒武纪至中奥陶世的地层中^[2]，如加拿大中寒武世伯吉斯页岩和美国上奥陶统布罗米德群（英语：Bromide Formation）等。^[3]^[4]

特征

这种腕足动物的体型较小，壳瓣双凸状，凸起平缓，呈长卵形、阔卵形或近三角形，壳体薄，由磷酸盐类组成^[5]，前缘一般呈宽圆状，朝壳喙方向逐渐缩小，壳喙位于假铰合面边缘。两瓣壳近相等，腹壳稍长且假铰合面高，在假铰合面顶端长有肉茎管。腹壳内可见盾状肌肉瘢痕区，顶肌痕呈心形，中央肌痕则呈小的三角形，后侧肌痕不明。背壳内有时可见一条狭窄的中脊。壳表面有同心状饰纹，内层壳有放散状花纹。^[2]
