Jane, the best-preserved and most complete juvenile Tyrannosaurus rex yet found, on display at the Burpee Museum. Jane (BMRP 2002.4.1) is a juvenile Tyrannosaurus rex or Nanotyrannus lancensis discovered in the Hell Creek Formation in southeastern Montana during the summer of 2001 by Carol Tuck and Bill Harrison, team members of an expedition led by Burpee Museum curator Michael Henderson, [1 ...
The smallest known Tyrannosaurus rex individual (LACM 28471, the "Jordan theropod") is estimated to have weighed only 29.9 kilograms (66 lb) at only 2 years old, while the largest, such as FMNH PR2081 ("Sue"), most likely weighed about 5,654 kg (12,465 lb), estimated to have been 28 years old, an age which may have been close to the maximum for ...
Mounted skeletons of different age groups, Los Angeles Natural History Museum. The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have ...
Victoria is estimated at the age of around 18–25 at the time of her death 65 million years ago. Her skeleton includes approximately 199 bones and nearly complete skull, accounting for about 65% of the total skeleton, making her the second most complete T. rex skeleton discovered to date (behind “Sue” for completeness).
His findings, published in 2019, yielded that Scotty is the largest (in weight and length), having out-measured the previous largest known Tyrannosaurus rex: Sue of the Chicago Field Museum (FMNH 2081). [13] After prolonged study of the growth patterns in the bones, "Scotty" was also declared as one of the oldest known T. rex fossils at 30 ...
The holotype was named as Tyrannosaurus bataar by Evgeny Maleev as Tyrannosaurus bataar. [7] The genus Tarbosaurus was also described in the same year based on PIN 551–2, a specimen with a skull and skeletal remains discovered by the same expedition in 1948 and 1949 as Tarbosaurus efremovi. [8]
However, there is no direct evidence T-Rex and Triceratops ever fought. Furthermore, a lot of Triceratops only had traces indicating scavenging. Yet healed injuries on either a T-Rex or Triceratops would be a clear sign of a fight. [18] A juvenile T-Rex has a bite force of 5,641 newtons compared to the 35,000 newtons of a full-grown adult.
