<P> Two of the replicas (Tyrannosaurus and Brontosaurus) are still on display at Dinosaur Valley State Park near Glen Rose, Texas . Another, a model of a Trachodon, has been displayed at Brookfield Zoo outside Chicago, Illinois . A replica of a Triceratops is either owned by the Kentucky Science Center and was being stored outdoors at an industrial park in South Louisville, Kentucky in 2016 or was donated by Sinclair to the Smithsonian Institution and is on display as "Uncle Beazley" in the National Zoological Park in Washington, D.C. </P> <P> In 1955, Sinclair ranked 21st on the Fortune 500; by 1969, it had fallen to 58th . </P> <P> In 1969, Sinclair was acquired by the Atlantic Richfield Company (ARCO). Federal antitrust provisions required the new entity to divest itself of certain Sinclair assets, and as a result, the East Coast operations of Sinclair were sold to BP (which has since purchased ARCO). After the acquisition by ARCO, the dinosaur was phased out, but at least one service station, in Winona, Minnesota, retained the original look through the 1980s . Many Sinclair stations in the Midwest continued to use the dinosaur logo along with ARCO's "diamond spark" logo . At least some Sinclair stations partially retained the Sinclair brand for a time, using ARCO's blue rectangular logo including the "spark" graphic, but with the word "Sinclair" substituted for ARCO . </P> <P> In 1976, ARCO spun off Sinclair by selling certain assets to Robert (Earl) Holding . Sinclair has been owned by the Holdings since 1976 . Assets divested in the spin - off included ARCO's retail operations in the region bounded by the Mississippi River and the Rocky Mountains, and the rights to the Sinclair brand and logo, resulting in many stations along Interstate 80 keeping the dinosaur logo . The ARCO stations in Texas, New Mexico, Illinois and some portions of Oklahoma were not affected by the divesture, and they continued as part of ARCO until ARCO pulled out of those states in the 1980s . </P>
