"Suciasaurus rex becomes official Washington state dinosaur after Gov. Inslee signs bill", KING-TV, May 5, 2023. Accessed May 8, 2023. "Washington officially has its first state dinosaur. Gov. Jay Inslee signed House Bill 1020 on Thursday, which designates the Suciasaurus rex as the official dinosaur of the state of Washington. Following the bill signing, Inslee recognized eighth-grader Athena Tauscher as 'Washingtonian of the Day' for her work on the bill.... The dinosaur represents the first dinosaur fossil ever found in Washington state by paleontologists back in 2012. The fossil belonged to a therapod, a two-legged meat eater like the Velociraptor and the Tyrannosaurus rex, according to the Burke Museum."
