摘要
摘要在美国蒙大拿州南部的三叶草组(下白垩世)发现了一种新的兽脚亚目恐龙——Deinonychus antirrhopus。该物种的特点是高度特化的足趾，在第二趾上有一个非常大而锋利的爪子，一个高度猛禽的手，有一个非常灵活的腕骨，以及一个特殊的尾鳍系列，有非常长的前关节和chevron棒。这一新物种与阿尔伯泰斯龙(dromaeo - albertensis)关系密切，后者具有类似的第二个足趾特化特征，被称为Dromaeosauridae科(=Dromaeosaurinae Matthew and Brown, 1922)。其他具有类似类型结构的物种可能属于这个科，包括不相等窄龙、蒙古伶盗龙和蒙古龙。
A NEW THEROPOD DINOSAUR FROM THE LOWER CRETACEOUS OF MONTANA
Deinonychus antirrhopus, a new genus and species of theropod dinosaur is described from the Cloverly Formation (Lower Cre taceous) of southern Montana. The species is characterized by a highly specialized pes bearing a very large, trenchant claw on digit II, a highly raptorial manus with a very mobile carpus, and a specialized caudal series with extremely long prezygapophyseal and chevron rods. The new species is closely related to Dromaeo-saurus albertensis, which features similar specialization of the second pedal digit, and is referred to the family Dromaeosauridae (=Dromaeosaurinae Matthew and Brown, 1922). Other species with comparable pes structure that may be referred to this family are Stenonychosaurus inequalis, Velociraptor mongoliensis and Saurornithoides mongoliensis.
