content: This specimen is an Ammonite. Ammonites are an extinct group of marine mollusks, living 400 to 66 million years ago. Ammonite shells are chambered, each chamber is divided by thin walls (septa) with the animal living only in the largest chamber. As the animal grew, new chambers were created and septa were secreted to partition off the old chamber. Ammonites were able to regulate their buoyancy using a siphuncle (living tube of tissue) connected to the empty chambers to contral gas content. Though they resemble modern nautiluses, ammonites were more closely related to modern soft-bodied cephalopods (octopuses, squids, and cuttlefish). This specimen was collected in El Indio, Texas.
