Sauroposeidon

Intro Sauroposeidon (/?s??ro?po??sa?d?n/ SOR-o-po-SY-d?n; meaning "lizard earthquake god", after the Greek god Poseidon[3][4]) is a genus of sauropod dinosaur known from several incomplete specimens including a bone bed and fossilized trackways that have been found in the U.S. states of Oklahoma, Wyoming, and Texas. Sauroposeidon Temporal range: Early Cretaceous (Aptian–Albian), 118–110 Ma[1] Pre??OSDCPTJKPgN Skeletal reconstruction of the holotype of S. proteles Scientific classificationEdit this classification Domain: Eukaryota Kingdom: Animalia Phylum: Chordata Clade: Dinosauria Clade: Saurischia Clade: ?Sauropodomorpha Clade: ?Sauropoda Clade: ?Macronaria Clade: ?Somphospondyli Genus: ?Sauroposeidon Wedel, Cifelli & Sanders, 2000 Species: ?S. proteles Binomial name ?Sauroposeidon proteles Wedel, Cifelli & Sanders, 2000 Synonyms Superposeidon Brochu, Long, McHenry, Scanlon, & Willis, 2002 (lapsus calami)[2] Paluxysaurus jonesi Rose, 2007 The fossils were found in rocks dating from near the end of the Early Cretaceous (Aptian–early Albian), from about 113 to 110 million years ago, a time when sauropod diversity in North America had greatly diminished. It was the last known North American sauropod prior to an absence of the group on the continent of roughly 40 million years that ended with the appearance of Alamosaurus during the Maastrichtian. While the holotype remains were initially discovered in 1994, due to their unexpected age and unusual size they were initially misclassified as pieces of petrified wood. A more detailed analysis in 1999 revealed their true nature which resulted in a minor media frenzy, and formal publication of the find the following year.[5] Paleoecological analysis indicates that Sauroposeidon lived on the shores of the Gulf of Mexico, in a river delta. Extrapolations based on the more completely known Brachiosaurus indicate that the head of Sauroposeidon could reach 16.5–18 m (54–59 ft) in height with its neck extended, which would
