Specimen TE-036, nicknamed “Roosevelt” is a premium quality composited example of the “Tyrant Lizard King,” Tyrannosaurus rex. It is named for President Franklin D. Roosevelt, after two partial T. rex specimens were discovered south of Fort Peck Lake, a monumental hydroelectric dam project constructed by the Army Corp of Engineers under FDR’s New Deal in 1940.
Garfield County, Montana, which lies in the shadow of the reservoir, has produced some of the highest quality specimens of Tyrannosaurus rex that have been recovered. “Roosevelt” takes his place alongside composite T. rex specimens including those exhibited at the American Museum of Natural History and the Natural History Museum in London, UK. “Roosevelt” is truly a beautiful and exciting display specimen, fully prepared and mounted for exhibition.
The material composited to complete TE-036 dates to the Maastrichtian age of the Late Cretaceous epoch, roughly 72 – 65.5 million-years ago. Tyrannosaurus rex was among the last of the dinosaurs extant at the time of the extinction which abruptly ended the Cretaceous.
