From today's featured articleThe Edmontosaurus mummy in the American Museum of Natural History is an exceptionally well-preserved fossil of a dinosaur, the first found to include a skeleton encased in skin impressions; almost two-thirds of the skin is preserved. Discovered in 1908 in the United States near Lusk, Wyoming, it is ascribed to the species Edmontosaurus annectens, a hadrosaurid (duck-billed dinosaur). It was discovered lying on its back, its neck twisted backwards and its forelimbs outstretched. After dehydration and burial of the carcass, bacteria consolidated the surrounding sediments, resulting in its excellent preservation. Skin impressions found in between the fingers were once interpreted as evidence for an aquatic lifestyle. The mummy was found by fossil hunter Charles Hazelius Sternberg and his three sons in the Lance Formation. Although Sternberg was working under contract to the British Museum of Natural History, Henry Fairfield Osborn managed to secure the mummy for the American museum. (Full article...)

Today's featured picture
Portsmouth Cathedral, officially known as the Cathedral Church of St Thomas of Canterbury, is an Anglican cathedral church in Portsmouth, England. It is the cathedral of the Diocese of Portsmouth and the seat of the bishop of Portsmouth. The cruciform building was constructed in the Romanesque style on land donated by Norman lord Jean de Gisors in the 1180s and dedicated to Saint Thomas Becket, who was martyred around ten years earlier. It was made a cathedral upon the establishment of the Diocese of Portsmouth, which was split from the Diocese of Winchester in 1927, after which it was extended in a "Neo-Byzantine" style by Charles Nicholson. This picture shows the cathedral's chancel, which, along with the transepts, are the only remaining sections of the original medieval building. The baptismal font, made to a ninth-century Greek design, is placed in the centre. Photograph credit: David Iliff
