For two days in December, Brigham Young University's Earth Science Museum, 1683 N. Canyon Road, will open the doors at its non-profit museum for a Christmas open house.

The first dinosaur bones found in the western part of North America are on loan from the Smithsonian Institution. They will be on exhibit at the Dec. 14 and 15 event. Hours on Dec. 14 are 5 to 9 p.m.; the hours will be 1 to 5 p.m. Dec. 15.Also planned is a dinosaur Christmas tree and a sale at the gift shop with proceeds going to help support the museum.

The new exhibit features bones discovered in 1859 by John Newberry, a scientist who accompanied a U.S. Army expedition to the West. It was common practice for a scientist to participate in such expeditions. This one, led by Capt. John McCombe, searched for where the Colorado and Green Rivers joined. The bones were found in what is known today as the east canyon of the Canyonlands.

Also new to the museum will be a photographic display of BYU's field work in southwestern Colorado at the Dry Mesa quarry. Among the photographs will be some of Walter Cronkite during a recent visit to BYU and the quarry.
