NEW Dinosaur Bone Fossil Fragments
Fragments of fossilized dinosaur bones from the Cretaceous period, which was 145.5-65.5 million years ago. Though these fragments may be too small to identify their species with certainty, we can narrow the possibilities based on their age and location of discovery. A 2016 study estimated that there lived about 2,000 non-avian species of the clade Dinosauria during this period. So far, paleontologists have identified and named about half this many. Please expect some natural variation. Includes a detailed info card.
