Big Al, often called "Al" for short, is a young male Allosaurus rescued from Late Jurassic Wyoming. Saved as a mature, 6-year-old adolescent, Al has since then grown up to be a fully grown male. He resides with his mate Alice in their enclosure.


Al possesses many traits not seen in other Allosaurus. Much like Sue, he is tenacious, cunning, persistent, and rather intelligent for a dinosaur, let alone, an Allosaurus. Additionally, when he was first saved, Al was a mature adolescent as opposed to a full-grown adult. Originally a 6-year-old adolescent that stood 13 ft. (4 m) tall, measured 32 ft. (10 m) long, and weighed 3 tons (6,000 lbs.), Al has since grown into true adulthood. Now around a decade old, he measures 38 ft. (11.8 m) in length, stands 16 ft. (5 m) tall, and weighs up to 5 tons (10,000 lbs.). One of the largest terrestrial carnivores of the park, he is also capable of running at speeds as fast as 21 mph.
