ROCK products • OCTOBER 2014 64 LAST CALL I t's not clear how the unnamed di‐ nosaur died 100‐120 million years ago, but it's been only 30 since he fi‐ nally encountered a predator he could‐ n't outrun: Atlas Copco equipment. "Not every company has a dinosaur species named after it," said Sofie Gie‐ len, Atlas Copco's marketing communi‐ cations director, in commemorating the 30th anniversary of the discovery of Atlascopcosaurus. "Three decades later, we're still extremely proud of the fact that our equipment helped un‐ earth the fossilized skeleton of Atlas‐ copcosaurus so it could be shared with the entire world." Atlascopcosaurus was an estimated 6.5‐ to 13‐ft. long and weighed 276 lb. The dinosaur belonged to the Hyp‐ silophodontidae family and lived dur‐ ing the early Cretaceous Period. Scientists infer that it was a small, bipedal herbivore that would have for‐ aged for its food and stayed out of the way of larger, carnivorous predators. Thomas H. Rich, PhD, a paleontologist from the Museum of Victoria, Australia, and Patricia Vickers‐Rich from Monash University, Melbourne, discovered At‐ lascopcosaurus at Dinosaur Cove, a fos‐ sil‐rich area on the southeast coast of Australia, close to Victoria. During Rich's first visit to the area in 1980, he and two colleagues revealed fragments of rock‐embedded bone. Four years later, a group of hundreds of student volunteers, paleontology scientists and miners began excavations. The research group's equipment in‐ cluded Atlas Copco rock drills, pneu‐ matic tools and compressors. The digging teams often worked in dark, narrow tunnels, which at times were muddy and slippery. The excavation site was located next to a steep cliff overlooking the sea, which compli‐ cated work even further. The fossils were embedded in layers of sand, mud and clay that had been pressed together into hard rock for millions of years. It was slow going, with the teams removing approxi‐ mately 66 lb. of hard rock for every 2 lb. of dinosaur bone. Ultimately, the excavation revealed At‐ lascopcosaurus loadsi. The specific name loadsi refers to Bill Loads, Atlas Copco's manager in Victoria who made the decision to support the project. When Rich and Vickers‐Rich named the fossil in 1989, they looked to the company whose equipment and expert assistance was so instrumental in the success of the dig.
