Ludwigia murchisoni Ammonite Fossil | Aalenian, Jurassic | Isle of Skye, Scotland UK | Alice Purnell Collection | Genuine with Certificate

Description

Fossil Type & Species:

This listing features a genuine ammonite fossil of Ludwigia murchisoni, a classic Middle Jurassic ammonite species from the Aalenian Stage. This well-preserved specimen was found on the fossil-rich coastlines of the Isle of Skye, Scotland, United Kingdom, and is part of the renowned Alice Purnell Collection, known for its rare and scientifically valuable British fossil specimens.

Geological Formation & Insight:

Ludwigia murchisoni is a species within the family Graphoceratidae, which is characterised by moderately involute shells with fine ribbing and occasional nodes. It is one of the most important biostratigraphic index fossils for the Aalenian Stage of the Middle Jurassic, dating to approximately 174 to 170 million years ago.

The Isle of Skye is one of the most geologically diverse fossil localities in the UK and represents a window into Jurassic marine and coastal environments. The Aalenian strata on Skye are primarily composed of siltstones and sandstones deposited in a shallow sea environment, where ammonites such as Ludwigia thrived.

These ammonites are thought to have been nektonic, free-swimming cephalopods that played an important role in the Jurassic marine ecosystem. Their fossilised shells are often preserved in limestone nodules or siltstone beds, frequently displaying excellent ribbing and coiling.
