The "Mini–T. rex" is a theropod-like animal which lives in the 4 Corners region of the Southwest United States. It is 3–5 feet tall, and weighs around 200 pounds or more. It has been given the nickname "Mini–T. rex" because it closely resembles a miniature version of Tyrannosaurus rex, according to most of the eyewitness reports. It is possible that this might be the same animal as the River Dinos, Mountain Boomer, and Oklahoma Raptor, which are all similar to it.
