Fossil hunter Alan Detrich believes a Triceratops skull a colleague found near Buffalo may be the biggest ever.
Detrich bought the skull from fellow fossil hunter John Carter, who lives in Buffalo. Detrich is planning on reselling the 8-foot skull.
Fossil experts won't know how the skull compares to others until it's cleaned up. That will likely take up to a year and a half.
Detrich, who has hunted dinosaur fossils since the 1990s, estimates this Triceratops was twice as big as an elephant. A normal triceratops is about the size of an elephant.
He says he expects the discovery to be quite valuable.
Triceratops lived in the Western U.S. about 66 million years ago.
