A 76-million-year-old Tyrannosaurus Rex skull is expected to find a new home this December when it goes to auction at Sotheby’s. The skull was excavated between 2020 and 2021 in Harding County, South Dakota – a place Cassandra Hatton, Sotheby’s head of science and popular culture, calls “the world capital for T. Rexes.”

The fossil, which measures 6 ½ feet in length, still has most of its external skull bones, and a number of teeth. Though the rest of the tyrannosaur’s skeleton was destroyed by erosion, Hatton believes that loss may be a boon at auction. “ When you think about it,” Hatton notes, “more people can fit a skull in their home than people who could fit a full dinosaur.”

The largest T. Rex skeleton ever found, nicknamed Sue, was also unearthed in Harding County. Sue currently resides in Chicago’s Field Museum, but Hatton believes Maximus will end up outside of an institution. “It’s the ultimate trophy,” Hatton said. “To place in one’s home.”

The skull bears two large puncture holes, which Hatton believes are evidence of a fight, most likely with a fellow T. Rex. “We don’t know that this is what caused the death of this animal, but we can tell that it did have a major battle during its lifetime,” she added.

Maximus, which Sotheby’s official listing calls “one of the best and most complete Tyrannosaurus rex skulls ever discovered” is slated to hit the auction block at 10:00AM EST, December 9th.
