Phylloceras andreae Fossil Ammonite – Callovian, Jurassic – Tulear, Madagascar

About the Fossil:

This well-preserved Phylloceras andreae ammonite fossil originates from the Callovian stage of the Middle Jurassic (~166-163 million years ago) and was discovered in Tulear, Madagascar. Phylloceras is a genus of phylloceratid ammonites, known for their smooth, involute shells with highly intricate and complex suture patterns. Unlike ribbed ammonites, these phylloceratids have a more streamlined and hydrodynamic shell, which may have allowed for enhanced swimming efficiency in Jurassic seas.

During the Middle Jurassic, ammonites like Phylloceras andreae thrived in warm marine environments, where they played an essential role in the oceanic food chain. Unlike many other ammonites, phylloceratids are considered deep-water cephalopods, making them particularly valuable for study and collection. The Callovian-aged deposits of Tulear, Madagascar, are renowned for their ammonite-rich formations, offering crucial insights into Jurassic marine life.

Description

Fossil Ammonite Identification

This listing presents a fossil ammonite identified as Phylloceras andreae (d’Orbigny, 1841), with the additional identification Callovian, Jurassic. The specimen is associated with TULEAR, Madagascar, and comes from the Alice Purnell Collection. Its scientific name and author citation make it an appealing addition for collectors who appreciate formally identified Jurassic fossils and the historical development of ammonite classification.

Geological Context

The Callovian is a stage of the Jurassic Period and forms part of the Middle Jurassic. Ammonites from this interval are especially valued by collectors because they provide a direct connection to Jurassic marine environments and the evolutionary history of extinct cephalopods. Ammonites were marine animals related to modern nautiluses, squid and cuttlefish. Their coiled shells were divided internally into chambers, with the animal occupying the living chamber as it grew.

Phylloceras andreae is presented here as a named ammonite species from the Callovian Jurassic. The combination of the genus, species name, author citation and geological stage gives the specimen strong educational value for fossil enthusiasts, students of palaeontology and collectors building a themed Jurassic or ammonite display. It can also provide an attractive focal point in a cabinet featuring fossils from Madagascar or material connected with the Alice Purnell Collection.

Locality and Collection

The locality information supplied for this fossil is TULEAR, Madagascar. Madagascar is well known among fossil collectors for its diverse geological record and distinctive fossil material. This specimen is specifically described as being from the Alice Purnell Collection, adding collection context to its presentation and making it suitable for collectors who value documented association with a named collection.

Display and Collector Appeal
