Usually documentaries are the documents that national geographic channel and history channel shows to their audience which are based on facts and techniques that have been used years ago to predict some things like age, size, lineage, height, weight, length etc. of the species that were discovered and recognized in this world.

The biggest question that the paleobiologist was trying to solve in this documentary was what is the reason of the T-rex dying and what is the sex of the T-rex. To find out this two questions they tried many different experiments and showed many modern days’ equipment to calculate the rings around the dinosaur, X- ray machine to see her femur, butcher knives and long knives to cut T-rex internal organs, CAT scan of brain etc. They found that T-rex was very young when she died because the rings that were surrounded by body was around 20 and T-rex are expected to live longer than 30
