- A study reveals T-Rex's tiny arms evolved due to its large skull and jaws, making claws unnecessary for hunting large prey like sauropods.
- Researchers found that smaller forelimbs in theropods were linked to the evolution of robust skulls, indicating a shift in hunting methods over time.
- The study suggests that as theropods adapted to hunt larger prey, their arms became less useful, leading to their gradual reduction in size.
