Rare Baculites Fossil Ammonite Kossmatia tenuistriata Upper Valanginian Specimen Cretaceous From Alice Purnell Collection

Description

Identification and Geological Age

This listing features a rare Baculites fossil ammonite identified as Kossmatia tenuistriata. The supplied geological identification places it in the Upper Valanginian of the Cretaceous period, providing an important time context for collectors interested in Mesozoic palaeontology, ammonites and fossil invertebrates. The associated location information supplied with the specimen is Italy.

Baculites and Ammonite Fossils

Baculites is widely recognised as a group of extinct ammonites with a distinctive straight or gently curved shell form, unlike the tightly coiled shells associated with many other ammonite fossils. Ammonites were marine cephalopod molluscs related to modern squid, cuttlefish and nautiluses. Their shells were divided into chambers by internal walls called septa, while the suture patterns formed where the septa met the outer shell.

These chambered shells played an important role in buoyancy and movement in ancient marine environments. Fossil ammonites are valued by collectors not only for their visual appeal, but also for the information they provide about ancient seas, evolutionary history and the changing distribution of marine life through geological time. The Upper Valanginian belongs to the Early Cretaceous, making this identification relevant to collections focused on Cretaceous fossils and stratigraphic palaeontology.

Collector Interest

Kossmatia tenuistriata is the supplied identification for this fossil specimen. It is suitable for fossil collectors, ammonite enthusiasts, geology students, museum-style displays and educational collections. The combination of a Baculites identification, the named Kossmatia tenuistriata designation and Upper Valanginian Cretaceous age gives the piece strong appeal for anyone building a themed collection of ammonites or marine fossils.

This specimen can be displayed as a conversation piece or used to support learning about ammonite classification, chambered shells, Cretaceous marine ecosystems and the geological timescale. It also makes a distinctive gift for collectors interested in palaeontology, historical geology and natural history.
