    Tyrannosaurus rex (Latin for "king tyrant lizard")
    Late Cretaceous
    Hell Creek Formation, Harding County, South Dakota

    Tyrannosaurus rex was the largest, most powerful carnivorous dinosaur (aka theropod) of all time, and the largest land carnivore of any type in our Earth's history. It measured up to 43 feet in length and weighed up to 8 tons (16,000 lbs).
    Its massive skull measured up to 5 feet long and was lined with huge spike-like teeth that were more robust than the teeth of any other theropod. Its skull was narrow in the front and extremely wide in the back, allowing for the eye sockets to point well forward and indicating the presence of excellent binocular vision, which would be necessary to solve time-distance problems required to effectively intercept its prey at running speed. Because the skull was so massive and heavy, T. rex needed a substantial counterbalance in the form of a long heavy tail. The neck was short and the neck muscles huge to support the gigantic skull and absorb the shock of impact during the very violent attacks that T. rex would initiate as it would slam into its prey, mouth first, at high speed. T. rex teeth were very robust so that they would more effectively transmit the energy of impact into the victim's body and gouge, rather than cut, huge chunks of flesh out of the prey as T. rex bore down with its powerful jaws. T. rex had the greatest biting force of any large theropod, so it appears that the great jaw strength was an evolutionary adaptation to its unique "gape-jawed" collision hunting style. The evidence clearly shows that Tyrannosaurus rex was truly the "King of Dinosaurs".

    This tooth is from the dentary region or lower jaw. It exhibits pristine, natural lustrous surfaces and a gorgeous banded chocolate-brown color with orange and yellow checking and highlights. It also has an interesting wear spot or "facet' near the tip where the tooth was ground flat by the repeated occlusion with the corresponding upper tooth. The serrations on the cutting edges are in excellent condition. An exceptionally high quality specimen, with only a small percentage of restoration, measuring 3 3/8 inches long by a massive 1 3/8 inches across the base.
