Description

Spectacular Multiple Ammonite Grouping Fossil Display Specimen! Excellent detail with shimmering iridescence to the shells. Photos don't do this wonderful specimen justice! Such a nice cluster with at least 10 ammonites showing the two largest at 6" and 8". Perfect size for display at 10 inches high and about 6 inches wide.
Ammonites (Ammonoidea) are prehistoric animals that first appeared about 240 million years ago! (WOW) They descended from another cephalopod called a Bacrite that date back about 415 million years ago. Ammonites are the most common and abundant fossils found today. Typical of cephalopods, ammonites were predatory, carnivorous creatures, with beaks inside their ring of tentacles, like squids. They were prolific breeders, lived in schools, and swam through shallow, warm waters by squirting jets of water through their bodies. They did this by siphoning air and pumping it back out through a "siphuncle" which reached into the interior chambers of their shell. They unfortunately went extinct with the dinosaurs (65 million years ago).
