Species: Nanotyrannus iancensis Age: Late Cretaceous (66 mya) Location: Brusett, Montana Formation: Hell Creek
Item #A111: Huge Nanotyrannus iancensis tooth in great condition. Some enamel wear on the upper posterior carina, which is missing denticles (serrations). The average Nanotyrannus tooth is 1 ½”, while this one measures 2 ¼” around the curve. Great color and details make it a wonderful addition to any collection. Full, straight-line dimensions: 0.42 oz, 2” x ⅞” x ⅜”
Nanotyrannus iancensis, which translates to “dwarf tyrant,” grew to be over 17’ in length, and weighed around 1 ton. Their smaller size and thin, curved teeth made them a more agile predator than the more cumbersome T. rex.
Fun fact: There is a great deal of controversy over whether N. iancensis is a distinct species or merely a juvenile T. rex. Many paleontologists point to significant differences in tooth size, shape, and quantity to argue for the validity of the species.
