Trachodon mummy
The Trachodon mummy is a very well preserved fossil of ''Edmontosaurus annectens'', a duckbilled dinosaur. It was found by Charles Hazelius Sternberg and his three sons near Lusk, Wyoming, USA in 1908. Although Sternberg was working under contract to the British Museum of Natural History, Henry Fairfield Osborn of the American Museum of Natural History managed to secure the mummy for $2,000. Though referred to as a 'mummy', no skin or muscle tissue is actually preserved, only their impressions in the rock.
==The mummy==
The mummy was found lying on its back with its head pulled under its body, while its right arm stuck out into the air. The skin of the chest and abdominal region was pulled into the body cavity, and the tail, hind feet, and hind portion of the pelvis had eroded away. The hands of the ''Edmontosaurus'' and other species unearthed later suggested the presence of webbed feet, but was later found to be inconsistent with footprint evidence. It has since then been proposed that hadrosaur forefeet have a hard, horseshoe-shaped pad. The webbed skin was later found to be from the postmortem displacement of loose skin of the hand.
