The Nanotyrannus also has longer claws than Tyrannosaurus Rex.According to Danny New, the rare fossil of Nanotyrannus will go up for auction on October 27, 2026, at the Manhattan auction house.

If one looks carefully, it seems like a downsized version of Tyrannosaurus Rex. However, Nanotyrannus does have a gaping jaw with razor-sharp teeth. The proportion of its arms, legs, and claws is larger than that of T. Rex. The skeleton's structure confirmed that it is indeed a distant cousin of T. Rex.According to KCRA 3, the fossil is around 6.5 feet tall and 20 feet long, making it one of the rarest fossils to exist. As per reports, only three such skeletons exist as of now.Cassandra Hatton, the Head of Science and Natural History at Sotheby's, said that for a long time T.rex was considered the only apex predator of the Cretaceous. However, the discovery of creatures like Nanotyrannus makes the prehistoric world even more fascinating. Speaking about T.rex and Nanotyrannus, Hatton said:"We now know that they coexisted. They lived alongside each other, occupying distinct niches in the ecological system "In 1942, a scientific debate kicked off with the discovery of the first Nanotyrannus head. It was called the Cleveland Skull and displayed at the Cleveland Museum of Natural History. In October 2025, research concluded that Nanotyrannus was a distinct genus of T.rex.According to KCRA 3, scientists found around 150 key differences between T.rex and Nanotyrannus. An adult Nanotyrannus is half the size of an adult T.rex. Instead of T.rex's flabby arms, Nanotyrannus has longer arms and claws.Nanotyrannus also has differently shaped teeth. Hatton explained:"Those teeth would slash the meat off of the animal it was hunting. It went after faster prey,"Hatton continued:"You look at a T. rex, it's big, lumbering. It went after slower prey, and it would eat the whole thing."The rare fossil of Nanotyrannus is named Jodi after the famous Montana rancher Jodi Pierson. Pierson discovered it on her land in 2019. The discovery and excavation are available to watch on the Discovery Channel's documentary series Dino Hunters.Scientists have opposed the sale of fossilsSome scientists and researchers have opposed the auction of the fossil. The Society of Vertebrate Paleontology has argued that such pivotal fossils should be publicly displayed in museums and not sold privately.Hatton argued that there are not enough professional dinosaur hunters and credited them for finding dinosaurs like Nanotyrannus. Hatton suggested that private diggers are required to achieve these results. Sotheby's previously sold a T.rex fossil for $50.1 million last summer.Follow SoapCentral for more such updates.
