In 2012, Naturalis Biodiversity Center at Leiden, the largest natural history museum of the Netherlands, planned to open a new exhibition hall in 2017.In order to increase the structural number of visitors from 300,000 to 400,000 per annum, the management decided to try and procure an authentic Tyrannosaurus skeleton, preferably one excavated by the museum itself.
Stan Sacrison, an amateur paleontologist, was responsible for the initial discovery of Stan's bone fragments in 1987, and as a result is the namesake for the T. rex.He was out looking at plant life in South Dakota when he spotted Stan's pelvis visible in the side of a cliff. [3]
The final cost was US$8,362,500. [19] [20] [21] Sue remains one of the most expensive dinosaur fossils ever sold, only surpassed in 2020 with the sale of Stan the T. rex. for $31.8 million, and subsequently in 2024 by Apex the Stegosaurus, which sold for $44.6 million.
The specimen's considerable size places it within the range of known T. rex individuals, suggesting the presence of large tyrannosaurids during the Campanian stage (~75 million years ago), a temporal range earlier than the established Maastrichtian age (~68–66 Ma) for Tyrannosaurus rex. However, the exact age and provenance of CM 9401 remain ...
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]
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).
