中文百科
三瘤齿兽属三瘤齿兽属（学名：Tritylodon）是犬齿兽亚目三瘤齿兽科的一属，而三瘤齿兽类是最先进的犬齿兽类之一。三瘤齿兽生存于侏罗纪早期，曾与恐龙共同存活在同一时期。三瘤齿兽拥有许多现代哺乳动物的特征，因此过去曾被归类于哺乳动物。但由于三瘤齿兽仍保有类似似哺乳爬行动物的下颌骨头、头颅结构，目前被归类于合弓纲（似哺乳爬行动物）。
英语百科
Tritylodon 三瘤齿兽属Tritylodon (Greek for 3 cusped tooth) was a genus of tritylodont, one of the most advanced group of cynodont therapsids. They lived in the Early Jurassic and possibly Late Triassic periods along with dinosaurs. They also shared a lot of characteristics with mammals, and were once considered mammals because of overall skeleton construction. That was changed due to them retaining the vestigial reptilian jawbones and a different skull structure. Tritylodons are now regarded as synapsids (often called "mammal-like reptiles"). |
