Description
Fossil Type & Species:
This listing features a genuine ammonite fossil of the genus Dactylioceras, a highly recognisable and widely distributed ammonite from the Aalenian Stage of the Middle Jurassic Period. This beautiful and scientifically significant specimen was collected from the Isle of Skye, Scotland, UK, and is part of the prestigious Alice Purnell Collection, known for its academically curated and collector-grade fossils.
Geological Formation & Insight:
Dactylioceras is one of the most well-known ammonite genera in Jurassic paleontology. Characterised by its tight coiling, fine radial ribbing, and discoidal shell, Dactylioceras is commonly used as a biostratigraphic marker across Europe and beyond. Though most commonly found in Lower Jurassic strata, occurrences in the Aalenian Stage (~174–170 million years ago), particularly in transitional sequences, highlight the evolutionary persistence of the genus.
The fossil was recovered from marine deposits on the Isle of Skye, one of the most geologically diverse locations in the UK. During the Middle Jurassic, Skye lay beneath a shallow sea rich in marine life. The island’s fossiliferous shales and mudstones yield beautifully preserved ammonites, often retaining intricate shell detail and suture lines.
Skye is a key location for Jurassic research, with continuous sequences offering insight into faunal evolution, paleoecology, and marine biodiversity.
