Summary[edit]
DescriptionPseudoprotoceras fossil.jpg |
English: Pseudoprotoceras longinaris Cook, 1934 - fossil mammal skeleton with unborn fawn from the Eocene of Nebraska, USA. (public display, Nebraska State Museum of Natural History, Lincoln, Nebraska, USA)
From museum signage: Hornless "deer" with unborn fawn Most living creatures die without leaving any permanent physical record of their existence. Fossilization is a rare event, especially the preservation of complete skeletons like this one. Fossils that capture a moment shortly before an animal gives birth are truly exceptional. This dramatic specimen of a small deer-like mammal was found by L.G. Tanner in the "Chadronia Pocket" near Crawford in 1938. Lloyd Tanner always considered this skeleton to be his first solo fossil discovery. It was found in June of 1938 in the Chadron Formation of Dawes County, Nebraska. Skulls and jaws of this little ruminant are extremely rare and here was a complete skeleton containing unborn young! Classification: Animalia, Chordata, Vertebrata, Mammalia, Artiodactyla, Ruminantia, Protoceratidae Stratigraphy: Big Cottonwood Creek Member, Chadron Formation, Upper Eocene Locality: Chadronia Pocket, ~7.8 miles north of the town of Crawford, northwestern Dawes County, northwestern Nebraska, USA (NW 1/4, NE 1/4, NW 1/4, Section 36, T33N, R52W) See info. at: en.wikipedia.org/wiki/Pseudoprotoceras |
