Big Al is the most famous Allosaurus due to the heavy amount of injuries he sustained during his life.
Al was born into the world via his mother and raised to hunt. During his younger years Al was usually very similar to others. However during mating season Al tried to court a larger female. She ended up crushing his ribs, right arm, and seared into his neck. While not dead this hampered his hunting abilities. Once the dry season arrived during an ambush Al broke his toe and thus became infected. After a few months due to his injuries and infection the poor animal died.
- Big Al's CGI model is far more detailed than it's appearance in Walking with Dinosaurs.
