Pseudogrammoceras striatulum Ammonite Fossil | Aalenian, Jurassic | Isle of Skye Scotland UK | Alice Purnell Collection

Description

Fossil Type & Species:

This listing features a genuine ammonite fossil of Pseudogrammoceras striatulum, an elegant and scientifically significant ammonite species from the Aalenian Stage of the Middle Jurassic Period. Collected from the rugged and fossil-rich Isle of Skye, Scotland, United Kingdom, this rare specimen is part of the respected Alice Purnell Collection, curated for its academic and collector value.

Geological Formation & Insight:

Pseudogrammoceras striatulum is part of the Graphoceratidae family, characterised by its thin, discoidal shape, tight coiling, and finely striated shell ornamentation. It is a classic ammonite used in stratigraphic correlation across Europe, particularly marking key intervals in the Aalenian (~174–170 million years ago).

This specimen was discovered in the marine sedimentary rocks of the Hebrides Basin, deposited during a time when the area was submerged beneath a shallow Jurassic sea. These beds — part of the Great Estuarine Group and equivalent to other Lower-Middle Jurassic formations across the UK — often yield well-preserved cephalopods, including ammonites, belemnites, and bivalves.

The Isle of Skye is a globally recognised geological site, renowned for exposing continuous Jurassic sequences and for yielding high-quality ammonites in hard shales, mudstones, and limestone nodules. Specimens from this region often show beautiful detail and preservation, as seen in this Pseudogrammoceras fossil.
