Dinosaur Bone Fossil Fragments w/ Card

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.• Made in United States• Weight: 1.6 oz (45.36 g)• Dimensions: 4 x 4 x 4 in (10.2 x 10.2 x 10.2 cm)
