RARE Morrowites subdepressus Fossil Ammonite, Lower Turonian, Cretaceous: Menabe, Madagascar – 100% Genuine with COA

Description This RARE Morrowites subdepressus fossil ammonite is a remarkable specimen from the Lower Turonian Stage of the Cretaceous Period, discovered in the Menabe region of Madagascar. Morrowites subdepressus is an ammonite species known for its distinctively flattened, spiral shell. The Lower Turonian marks a time when marine life was thriving, and ammonites such as Morrowites subdepressus were an important part of the marine ecosystem. This fossil offers an outstanding example of ancient marine life, preserved in Madagascar’s rich fossil deposits. Geological Information: Geological Stage: Lower Turonian, Cretaceous (Approximately 94 to 89 million years ago) Depositional Environment: The Lower Turonian period saw the rise of shallow seas that spread across much of Madagascar. These seas were home to diverse marine life, including ammonites like Morrowites subdepressus. The Menabe region is well-known for its sedimentary deposits formed during this period, where marine organisms, such as ammonites, were preserved. The region offers excellent conditions for fossilization, making it a significant area for studying ancient marine life. Biozone: This fossil comes from the Lower Turonian biozone, which was a rich time for ammonites and other marine organisms. The Turonian period is characterized by abundant marine life, including the Morrowites genus, providing valuable insights into the marine ecosystems of the Cretaceous period. Fossil Features: Family: Morrowitidae Super Family: Morrowitoidea Order: Ammonitida Morphology: The Morrowites subdepressus ammonite has a distinctively flattened and spiral shell. The shell is evolute, showing clearly defined whorls, with strongly ribbed surface details. The ribs are prominent and run the length of the shell, creating a texture that is characteristic of this species. The flattened shape and sharp suture lines further define the ammonite, making it a unique specimen for collectors and enthusiasts of Cretaceous ammonites.
