The original idea of the bill came from high school student Mason Cypress Oury, who, accompanied by Rep. Leding, presented a modified version of the bill to a House panel, and answered questions. Among his reasoning for adopting the Arkansaurus as the state dinosaur Oury pointed out that Oklahoma, Texas and Missouri all have listed state dinosaurs, and Arkansas already has 24 designated state symbols, and since it was the 25th state to be admitted to the union, it made sense to add one more. The bill was approved by the governor February 17, 2017.

In March 1973, Dr. James
Harrison Quinn and Benjamin Clardy of the Arkansas Geological Commission went to the area on the Friday farm where the remains had been discovered, hoping to find more remains. The site was a pit that had been dug for road construction and the fossils had been taken from the

Nashville, Doy Zachry Jr., took the bones to his colleague at the University of Arkansas, paleontologist Dr. James H. Quinn, to view. Quinn recognized the fossilized remains as dinosaurian and prepared the bones. He took the remains to the annual meeting of
