In 2013 a team of Dutch palaeontologists found the skeleton of a Tyrannosaurus rex in Montana which was very complete and in excellent condition. Over half of the bones have been conserved and the skeleton is one of the largest ever found.

Although the study of the skeleton shows that Trix led a life fraught with infections, fractures and other wounds, her bones have been conserved remarkably well, without becoming deformed.

Trix is believed to have been a female and appears to be the specimen which lived the longest life of all those discovered to date.
