股骨长度:688mm
原文:The specimen BMRP 2002.4.1 consists of a nearly complete skull with associated postcrania, including a partial femur [estimated length, 68.8 cm; (7)] and complete tibiae.
——《Growing up Tyrannosaurus rex: Osteohistology refutes the pygmy “Nanotyrannus” and supports ontogenetic niche partitioning in juvenile Tyrannosaurus》
股骨+胫骨+第三跖骨长度:2120mm,体重:660kg
——《The fast and the frugal: Divergent locomotory strategies drive limb lengthening in theropod dinosaurs》
按照以上数据计算,(胫骨+第三跖骨长度)/股骨=2.08,这个比例太夸张了,矮暴龙“简”的速度是64.1km/h>63.4km/h的达科塔盗龙。
由于上面的股骨长度是估算的,两篇论文可能估算的长度不一样,所以拼起来计算的结果可能有误差。
求矮暴龙的腿部数据。
