A partial skull once believed to be from a T. rex is a newfound species, a study revealed. T. mcraeensis could shed light on why tyrannosaurs evolved into giants. T. rex’s older and equally ...
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]
The dinosaur's bones were discovered in a mine in Wales in the 1950s. A more recent analysis found that the ignored fossils are a distinct species.
Both Guanlong specimens compared to a human. Guanlong was a relatively small theropod, reaching 3–3.5 m (9.8–11.5 ft) in length and 125 kg (276 lb) in body mass. [2] [3] [4] Its fossils were found in the Shishugou Formation dating to about 160 million years ago, in the Oxfordian stage of the Late Jurassic period, [2] 92 million years before its well-known relative Tyrannosaurus.
While Albertosaurus was certainly large for a theropod, it was still much smaller than its larger and more famous relative Tyrannosaurus rex, growing up to 8–9 metres (26–30 ft) in length and weighing 1.7–3.0 metric tons (1.9–3.3 short tons).
