Ptychophylloceras sp. Fossil Ammonite – Callovian, Jurassic – Tulear, Madagascar

About the Fossil:

This beautifully preserved Ptychophylloceras sp. ammonite fossil originates from the Callovian stage of the Middle Jurassic (~166-163 million years ago) and was discovered in Tulear, Madagascar. Ptychophylloceras is a genus of phylloceratid ammonites, known for their smooth, involute shells with complex suture patterns and highly distinctive morphology, making them an intriguing species in the ammonite fossil record.

During the Middle Jurassic, ammonites like Ptychophylloceras sp. inhabited warm marine environments, where they played an essential role in ancient marine ecosystems. Unlike other ammonites, phylloceratids such as Ptychophylloceras are believed to have been deep-water species, with their streamlined shell structure suggesting enhanced swimming capabilities. The Callovian deposits of Tulear, Madagascar, are well-known for their ammonite-rich formations, providing valuable paleontological insights into the evolution of Jurassic cephalopods.

Description

Fossil Ammonite Identification

This fossil is identified as PTYCHOPHYLLOCERAS SP Fossil Ammonite and is recorded as Callovian, Jurassic. The specimen is associated with Tulear, Madagascar, providing an appealing connection to the fossil-bearing regions of Madagascar and the deep geological history of the Jurassic Period. Its identification makes it a distinctive addition to fossil collections focused on ammonites, Jurassic life and natural history.

Ammonites were extinct marine cephalopods related to modern squids, cuttlefish and nautiluses. Their fossils are especially valued because the coiled shell form is instantly recognisable and ammonites are important to the study of ancient marine ecosystems. The Callovian forms part of the Jurassic Period, an interval noted for diverse marine life and significant developments in the fossil record. This geological age gives the specimen strong educational interest for collectors, students and anyone fascinated by prehistoric life.

Geological and Collector Interest

The combination of Ptychophylloceras identification, Callovian Jurassic age and Tulear, Madagascar locality creates a compelling subject for display. It can complement collections featuring Jurassic fossils, ammonites, Madagascar material or specimens arranged by geological period. The fossil is also suitable for educational displays exploring extinct cephalopods, geological time and the way fossils preserve evidence of life from ancient environments.

Its labelled identification allows it to be presented as more than a decorative natural-history object. It offers an opportunity to discuss ammonite evolution, Jurassic marine environments in a general educational context and the value of locality and age information when documenting palaeontological specimens. The period and locality details make it particularly well suited to a cabinet display, classroom collection, study shelf or geology-themed interior.
