Lusotitan

Lusotitan is the name given to a genus of dinosaur from the Late Jurassic Period. It was a brachiosaurid sauropod with long forearms, one of the hallmarks of the brachiosaur family. Its fossils were found in the Lourinhã Formation, in Portugal, dating to the Tithonian stage of the Late Jurassic.

A partial skeleton was uncovered in Portugal in 1957; it is estimated that Lusotitan was 25 meters (82 feet) long. No skull has yet been found, but it would fit the typical brachiosaurid pattern with very high and open nostrils and spoon-shaped teeth. The type species is Lusotitan atalaiensis. Originally described as Brachiosaurus atalaiensis by Lapparent and Zbszewski in 1957, it was reclassified in 2003.
