English(EN) Meet ‘Smilodon’ — The Sabertooth Cat With A Bite Weaker Than A House Cat’s

研究发现：剑齿虎Smilodon咬合力出人意料地弱

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-01 12:00

对剑齿虎 Smilodon fatalis 的新生物力学模型显示，其咬合力远低于之前的假设，仅相当于一只大型家猫，而非狮子。研究人员发现，Smilodon 更依赖其强有力的前肢来制服猎物，一旦猎物被制服，就用其标志性的犬齿进行精确的、足以致命的撕咬。这种以强壮前肢和较弱咬合力为特征的捕猎策略，在不相关的谱系中独立进化，例如有袋类捕食者 Thylacosmilus，展示了趋同进化。 AI
