<p>A light brown stingray fossil, facing up on almost white stone.  To the left of the tail it is possible to see two tiny fins.</p>
<p>The narrow, paired fins at the base of the tail were used to position the female stingray to most effectively fertilize eggs as they were laid.  Catalog number FOBU408</p>
