Meet Mama & Max


Shhh... Be careful not to wake up Mama & Max

Come meet Mama and Max T. rex, the only full-size, permanent, animatronic tyrannosaurus dinosaurs (T. rex) in the United States. Mama stands a proud 25ft tall and 60ft long while her juvenile son Max is about 7ft tall. Some ask why he is "hairy"? Well, research shows that a baby tyrannosaurus were born with feathers, so the hair that you see on Max symbolizes what that research would show he would look like in that stage of his life.

Mama and Max ROAR during the spring and summer months or as long as the weather is permitting.
