What is the state dinosaur of Wyoming?

The state dinosaur of Wyoming is the Triceratops. This herbivorous dinosaur, which lived around 68-66 million years ago during the late Cretaceous period, was one of the largest ceratopsid dinosaurs. It is characterized by its large bony frill and three distinct facial horns. Wyoming, especially areas such as the Hell Creek Formation, is known for its rich fossil deposits, making it a hotspot for paleontological discoveries. The Triceratops was officially designated as the state dinosaur of Wyoming in 1994 due to its significance in the state’s fossil heritage.
