Description
Fossil Identification
This listing features Ptychophylloceras (Ptychophylloceras) subptychoicum (Neumayr, 1875), a fossil ammonite identified as Oxfordian, Jurassic. Ammonites were extinct marine cephalopods that lived in the oceans during the Mesozoic Era. Their fossilised shells are valued by collectors for their scientific importance, distinctive coiled form and connection to ancient marine environments.
The supplied identification places this specimen within the genus Ptychophylloceras and records the species as Ptychophylloceras subptychoicum. The author citation “(Neumayr, 1875)” forms part of the listed scientific name. This makes the piece an engaging addition to a fossil collection focused on ammonites, Jurassic palaeontology or historically documented marine life.
Geological Context
The specimen is identified as Oxfordian in age, a stage of the Jurassic Period. The Oxfordian belongs to the Late Jurassic and represents a time when marine environments covered extensive areas and supported diverse communities of cephalopods and other organisms. Ammonite fossils from Jurassic rocks are especially important in geology because their distribution and evolutionary changes can help researchers study ancient seas and establish relationships between rock layers.
The listed locality is Tulear, Madagascar. Madagascar is well known for its geological diversity and fossil-bearing regions, making specimens associated with the island attractive to collectors interested in world palaeontology and regional geology. The locality information provides useful context for displaying this ammonite alongside other Jurassic fossils or specimens from Madagascar.
Collection Information
From the Alice Purnell Collection. This provenance wording is supplied with the specimen and adds a documented collection association for collectors who value the history and presentation of individual fossils. The ammonite is suitable for a private fossil cabinet, educational display, geology study area or natural-history themed interior.

The photograph shows the actual specimen you will receive. Full sizing is shown in the photographs. Please review the images carefully for the complete visual presentation, visible shell features, surface character and overall appearance of this individual fossil. As with any natural fossil specimen, the photographs provide the best reference for its exact form and display presence.
Display and Collector Appeal
This Ptychophylloceras fossil ammonite offers a strong combination of named scientific identification, Jurassic age, Madagascar locality and collection association. It can be displayed as a standalone ammonite fossil or incorporated into a broader arrangement of Jurassic fossils, cephalopods, Madagascan specimens and geological curiosities. Its documented identification also makes it a useful conversation piece for collectors, students and anyone interested in palaeontology.
The specimen’s Oxfordian designation connects it to a significant interval of Jurassic marine history, while the named species gives the piece a more specific collecting focus than an unidentified ammonite. It is an attractive choice for fossil enthusiasts seeking a scientifically labelled Jurassic ammonite with certificate documentation and a stated collection background.
