Dinosaur size
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur "Argentinosaurus huinculensis", which is the largest dinosaur known from uncontroversial evidence, estimated to have been and long. Some of the longest sauropods were those with exceptionally long, whip-like tails, such as the "Diplodocus hallorum" (formerly "Seismosaurus") and the 33- to 35-metre-long (108–115 ft) "Supersaurus". The tallest was the "Brachiosaurus".
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.
