This remarkable heteromorph ammonite fossil from Morocco captures a fascinating moment in evolutionary history. Representing a mid-evolutionary point between pre-Cambrian trilobites and modern-day squid, this extinct marine creature showcases the unfurled, coiled structure that allowed it to control buoyancy through gas emissions in its shell. Over time, these ammonites developed protective spines to defend against predatory fish with armored, bony mouths. A truly unique and scientifically significant specimen, this fossil is an incredible display piece for collectors, historians, and paleontology enthusiasts alike.
Interesting Facts
Heteromorph ammonites lived during the Late Cretaceous period and are known for their unconventional, unfurled shell shapes.
Unlike their tightly coiled relatives, these ammonites evolved elongated, irregular shells, which scientists believe helped with buoyancy and movement.
Morocco is home to some of the world’s richest ammonite fossil deposits, preserving these extraordinary marine creatures in stunning detail.
