一具近乎完整的蒂勒蒂腱龙骨架和与之密切相关的多颗脱齿恐爪龙的发现，为恐爪龙是群居捕食者的说法提供了证据。对标本的分类进一步证实了腱龙是恐爪龙捕食者群体的特殊食物偏好。在兽脚亚目动物中，唯一被发现作为食物的其他特定动物是Compsognathus中的巴伐利亚龙和Coelophysis中的Coelophysis。这两个可能是机会主义偶然捕食或食腐的例子，但似乎恐爪龙主动捕食的是经过深思熟虑的食物选择——腱龙。
ABSTRACT The discovery of a nearly complete skeleton of Tenontosaurus tilletti and closely associated multiple shed teeth of the dromaeosaur Deinonychus antirrhopus provides evidence that may support the often repeated suggestion that Deinonychus was a pack-hunting predator. The taphonomy of the specimen adds weight to the additional conclusion that Tenontosaurus was the specific food preference of the Deinonychus predator population. Among theropods, the only other specific animals that have been found as unmistakable food objects are Bavarisaurus in Compsognathus and Coelophysis in Coelophysis. These two could have been examples of opportunistic incidental predation or scavenging, but it appears that Deinonychus actively preyed on a deliberate food choice, Tenontosaurus.
