Sarcosuchus were ambush hunters, eating anything that entered their watery homes from wee fish to large dinosaurs. These big beasties were the precursors to our modern crocodiles -- and they were big. Really big. Almost twice as large as their modern saltwater cousins, weighing in at 8-10 tons. They lived 50-60 years. Modern Saltwater & Nile crocodiles live 70-100 years on average. This scute and tooth are from the Elrhaz Formation, Gadoufaoua, Ténéré Desert, Niger.
