Kritosaurus Bone - SOLD 3.310" neolithic featuring a fossilized Spinosaurus toothThe mighty hadrosaurs were some of the most successful herbivores of the Cretaceous Period. The "duck bills" these dinosaurs are known for were not actually beaks but hundreds of small teeth, helping them chew through even the toughest vegetation. This specimen is a fossilized bone section from the Kritosaurus genus of the Hadrosaurid family. It measures 3. 310" and dates to around 77 million years ago.
