Suciasaurus (meaning "Sucia Island lizard") is the informal name given to the first dinosaur discovered in Washington.

Discovery and naming[]

A fossil theropod nicknamed "Suciasaurus rex" was discovered in 2012 at Sucia Island State Park in San Juan County of the U.S. State of Washington. It was the first dinosaur discovered in Washington state.[1][2] The finding was announced when Burke Museum paleontologists published a discovery paper in PLoS ONE. Prompted by a petition from students at an elementary school at Parkland, near Tacoma, the Washington State Legislature introduced a bill in 2019 to make it the official state dinosaur.[1][2][3]
