Alamosaurus
Alamosaurus (; meaning "Ojo Alamo lizard") is a genus of titanosaurian sauropod dinosaurs, containing a single known species, Alamosaurus sanjuanensis, from the late Cretaceous Period of what is now southern North America. Isolated vertebrae and limb bones indicate that it reached sizes comparable to "Argentinosaurus" and "Puertasaurus", which would make it the largest dinosaur known from North America. Its fossils have been recovered from a variety of rock formations spanning the Maastrichtian age of the late Cretaceous period. Specimens of a juvenile "Alamosaurus sanjuanensis" have been recovered from only a few meters below the Cretaceous-Paleogene boundary in Texas, making it among the last surviving non-avian dinosaur species.
Titanoboa: Monster Snake
Titanoboa: Monster Snake is a 2012 documentary film produced by the Smithsonian Institution. The documentary treats "Titanoboa", the largest snake ever found. Fossils of the snake were uncovered from the Cerrejón Formation at Cerrejón, the tenth biggest coal mine in the world in the Cesar-Ranchería Basin of La Guajira, northern Colombia, covering an area larger than Washington, D.C. The documentary premiered at the Smithsonian Channel on April 1, 2012, followed by a panel discussion from the scientists who spearheaded the research: Carlos Jaramillo from the Smithsonian Tropical Research Institute, Jonathan Bloch from the Florida Museum of Natural History and Jason Head from the University of Nebraska at Lincoln.
