Heteromorph Ammonite (Unfurled)



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