talon

Deinonychus, or "terrible claw" after the sickle-shaped talon on each hind foot, stood about 11 feet from head to tail and was a lithe predator..这种被称为恐爪龙（Deinonychus）的恐龙后足上存在镰刀般的利爪，从头到尾的身长约为3.3米，是一种非常敏捷的掠食者。

Most powerful is the rear talon, the killer claw, that can exert a force capable of cutting through a human wrist (which is why falconers wear thick gloves)..最有力的鹰爪是后边的哪一只，它是一个致命的鹰爪，甚至它能将人的手腕切断(这就是为什么守猎者要戴上厚手套)。
