Ammonite

Morocco

The heteromorph ammonite is a mid-evolutionary point between the pre-Cambrian trilobite and the modern-day squid. It developed spines to protect itself from fish with armored, bony mouths. These spines evolved to be buoyant and to control the gas emissions in their shells to allow them to rise from the ocean floor. This particular fossil is unfurled.
