Previously discovered T. rex skeletons were usually missing over half of their bones. [10] It was later determined that Sue was a record 90 percent complete by bulk, [11] and 73 percent complete counting the elements. [12] Of the 360 known T. rex bones, around 250 have been recovered. [1]
This sudden change in growth rate may indicate physical maturity, a hypothesis that is supported by the discovery of medullary tissue in the femur of an 18-year-old T. rex from Montana (MOR 1125, also known as "B-rex"). [51] Medullary tissue is found only in female birds during ovulation, indicating that "B-rex" was of reproductive age. [52]
