拍品描述: Fossil Petrified white molar teeth of Gomphotherium, 6 in.=15 cm. Weight: 1 lb. 9oz = 700g; Size: 6 x 3 x 2.5 inches = 15 x 7.5 x 6.2 cm; Age: 13.6 - 3.6 million years; Gomphotherium (/mfrim/; "Welded Beast") is an extinct genus of proboscid which evolved in the Early Miocene of North America from 13.6503.6 Ma, living about 10 million years. The genus emigrated into Asia, Europe and Africa after a drop in sea level (probably during the Tortonian epoch) allowed them to cross over. It survived into the Pliocene, and its remains have been found in Chile, France, Germany, Austria, Kansas, Tennessee, Pakistan, Kenya and Bosnia and Herzegovina.[3] Gomphotherium stood around 3 meters (9.8 ft) high with an estimated weight of 4-5 tons, and bore a strong resemblance to a modern elephant. However, it had four tusks; two on the upper jaw and two on the elongated lower jaw. The lower tusks are parallel and shaped like a shovel and were probably used for digging up food from mud. Unlike modern elephants, the upper tusks were covered by a layer of enamel. Compared to elephants, the skull was more elongated and low, indicating that the animal had a short trunk, rather like a tapir's. These animals probably lived in swamps or near lakes, using their tusks to dig or scrape up aquatic vegetation. In comparison to earlier proboscids, Gomphotherium had far fewer molars; the remaining ones had high ridges to expand their grinding surface. Gomphotherium inhabited dry wooded regions near lakes. A complete skeleton of Gomphotherium has been found at Mühldorf, Germany, in 1971.
