Fossils

An artist's rendition from the British science magazine Nature shows the world's biggest snake. Stunned scientists have found the fossilized remains of the world's greatest snake -- a record-busting serpent that was as long as a bus and snacked on crocodiles.

A handout photo released by Nature magazine shows a Precloacal vertebra of an adult Green Anaconda (Eunectes murinus),lighter colored vertebra dwarfed by a vertebra of the giant boid snake they named Titanoboa cerrejonensis, meaning ``titanic boa from Cerrejon,'' the region where it was found. Fossils from northeastern Colombia reveal the biggest snake ever discovered: a behemoth that stretched 42 feet or longer, reaching an estimated 1.27 tons.

An ammonite fossil from the cretaceous period is pictured during a news conference at the Obispado museum in Monterrey, northern Mexico, January 21, 2009. The National Institute of Anthropology and History (INAH) has finished the identification process of some 400 fossils seized from a store in 2006, in what anthropologists say is the most important paleontological retrieval in the country due to the quantity and variety amassed. The fossils include the remains of mammoths, dinosaurs, camels, horses, sharks and ammonites.
