The fossil of an extremely rare baby T-Rex has been listed for sale on eBay with a "buy it now" asking price of $2.95 million.

The listing, last updated on Tuesday, claims the artifact is "most likely the only baby T-rex in the world," adding that the specimen has a 15-foot-long body, 21-inch skull and serrated teeth. The fossil, which is believed to be 68 million years old, was reportedly listed by professional fossil hunter Alan Detrich.

"This Rex was a very dangerous meat eater. It's a RARE opportunity indeed to ever see a baby REX," the listing says. "Histology shows the specimen to be approximately 4 years old upon death. Reconstruction of the skull has been done by Curator of Vertebrate Paleontology (from Natural History Museum in FL)."

Detrich loaned the fossil to the University of Kansas Natural History Museum in 2017, according to The Guardian, where it was still on display when he listed the specimen on eBay. The skeleton was discovered by Detrich in 2013 and subsequently became his property.

Leonard Krishtalka, director of the University of Kansas' Biodiversity Institute, said in a statement last week that the university's Natural History Museum does not sell or mediate the sale of specimens to private individuals.

"Accordingly, the specimen on exhibit-loan to us has been removed from exhibit and is being returned to the owner. We have asked that the owner remove any association with us from his sale listing," he said.
