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.

Photos are representative of typical specimens. Some natural variation in size/shape should be expected.
