Arboreal Dinosaur

A Arboreal Dinosaur appears in Series 5.

Episode 5.5
During convergence, a anomaly opens in the ARC's car park, letting thru a curious arboreal raptor which investigates Lester's new car. Lester spots it thru a camera. He claims 'Now it's personal' and takes the lift down to the car park. Once he arrives he quickly dispatches the creature with an EMD. The fate of the creature is unknown, as Lester probably wouldn't have dragged the creature through the anomaly in 'His Best Shirt'.
