LARGE AMMONITE PLATE
<B>LARGE AMMONITE PLATE</B></I> Dactylioceras commune <BR>Jurassic <BR>Ohmden, near Holzmaden, Germany <BR>Ammonites are among the most esthetic of fossil. They have been discovered on almost every continent and became extinct 65 million years ago along with the dinosaurs. One of the many fascinating things about ammonites is that the beautifully graceful spiral that most ammonites' exhibit is so consistent in its expression that it only takes a single mathematical expression to define this shape. That mathematical expression is called 'the Involute of a Spiral'. The present specimen is from the classic locality of Holzmaden, Germany, which dates back to the Jurassic period over 170 million years ago. It is quite large, measuring 26 x 40 inches, and displays dozens of small ammonites and features 4 large individuals measuring up to 8 inches in diameter.<BR><BR><b>Shipping:</b> Requires 3rd Party Shipping (<a target="_blank" href="http://www.heritageauctions.com/common/shipping.php">view shipping information</a>)
