Fall," "Bone Bed," "Above Bone Bed," "West to Beside Sauropod," "Laura's Apatosaur," and "Cheryl's Blind" just to name a few. Out of all the dig sites discovered, the main concentration of bones belongs to one of the four following genera: Apatosaurus, Camarasaurus, Diplodocus or Allosaurus. During the winter, the excavation sites are closed to visitors, but over the summer months (late-May to mid-September) active digging occurs every day (weather permitting). Collections and Exhibits The museum is open all year round and hosts a gallery with more than 50 mounted skeletons, including a full mount of Supersaurus vivianae excavated from a quarry near Douglas, Wyoming. The replica skeleton on display is 106 feet long and is the first mount based on data from the second and most complete Supersaurus ever found affectionately named "Jimbo" (WDC DMJ-001) which was donated to the museum in 2003. Other dinosaurs present include a T rex, Triceratops, Medusaceratops as well as various Hadrosaurs, Stegosaurs and Allosaurs. One of the newest members to the museum is the almost 90% complete, composite skeleton of a Camarasaurus found on the property by staff and visitors, excavated over the past 20 years. There is also a collection of real and replica marine reptiles, and flying reptiles. From these times before and after the dinosaurs, the museum hosts an impressive display of pre-Mesozoic fossils, including numerous Devonian fish and invertebrates. The more modern displays include fossil camels, horses, rodents and nimravids (sabretooth cat like animals). The museum also houses a fully functional preparation lab, where staff and visitors can be seen cleaning, repairing and preserving fossils found on the property as well as from other locations around the country, all year long. Programs The Wyoming Dinosaur Center offers many programs that allow visitors to dig up dinosaurs. Starting end of May (depending on the weather) the Dig for the Day program starts. This program is for families and individuals that are interested in learning more about paleontology. The Dig for the Day begins at 8am and finishes at 5pm. All fossils found remain at the museum for science and research. Throughout the summer, many dates are available for the Kids' Dig. Children ages 8 to 12 learn all aspect of what The Wyoming Dinosaur Center does. They dig, work in the prep lab removing matrix from dinosaur bones and they learn molding and casting. Other programs include Dinosaur Academy, Senior Activities
