 The fossil was discovered in Colorado in 2022 on private land, and the fossil shows evidence of arthritis. I love that, suggesting that the animal lived to an advanced age. And of course, it's huge. It's 11 feet tall and 27 feet from nose to tail. Sotheby's is estimating that it'll sell for $4 million to $6 million. I feel like it's going to go for way more than that. I don't know. I feel like that's a pretty hot ticket item.
