Summary
| Description | RPR ‘‘ripper’’ behavioural model, illustrated by a small dromaeosaurid. (A) grasping foot holds on to prey. (B) hypertrophied D-II claw used as anchor to maintain grip on large prey. (C) predator’s bodyweight pins down victim. (D) beam-like tail aids balance. (E) low-carried metatarsus helps restrain victim. (F) ‘‘stability flapping’’ used to maintain position on top of prey. (G) arms encircle prey (‘‘mantling’’), restricting escape route. (H) head reaches down between feet, tearing off strips of flesh (may explain unusual deinonychosaurian dental morphology). Victim is eaten alive or dies of organ failure. |
