补充资料:多瘤齿兽类
多瘤齿兽类 Multituberculata 异兽亚纲中仅有的一类哺乳动物。其形态特征与习性和啮齿类相近 。早期多瘤齿兽体小如家鼠 ,后期则逐渐增大。多瘤齿兽头骨短,背视轮廓略呈三角形,颧弓之间的距离颇大。具数对大门齿。下臼齿齿冠狭长,具两排平行的瘤状齿尖,上臼齿则具 3 排。前部颊齿在有些属种中变成有细纹的刀片状牙齿。颅后骨骼具有较多原始特征,如其肩胛骨就与单孔类(鸭嘴兽)相近。一般认为多瘤齿兽是以植物为主的杂食性动物。多瘤齿兽最早出现在晚侏罗世,在晚白垩世和古新世达到顶峰,渐新世全部绝灭,延续时间超过1亿年,长于其他哺乳动物。多瘤齿兽化石主要发现于欧洲和北美。在亚洲蒙古国南部及中国内蒙古地区中部也有发现。 |
