Waterloo Bay is an area of foreshore in Larne, Northern Ireland.

Contents

The site is of interest to geologists because it provides an unusually clear, complete and accessible example of the sequences from Upper Triassic to Lower Jurassic, when the rock types changed from land to marine.

Protected StatusEdit

In 1995, Waterloo Bay was designated an Area of Special Scientific Interest for its geological importance.

In 2007, it was a candidate for Global Boundary Stratotype Section and Point (also known as a GSSP, or 'golden spike') to mark the base of the Jurassic system and Hettangian stage. although the Kujoch in Austria was chosen instead.

Early investigationEdit

Joseph Ellison Portlock studied the Triassic and Jurassic rocks of Ireland in 1843 as part of his engagement by Ordnance Survey Ireland.

In 1864 Ralph Tate made an investigation of the Triassic rocks of Co Antrim, which he reported to the Geological Society of London.

The 'Larne Sea Dragon'Edit

In 1999, an ichthyosaur, also popularly known as the 'Larne Sea Dragon' or 'Minnis Monster' was found in the Langport Member strata by Brian McGee. Remains were found of the backbone and rib cage, scattered pieces of the front limbs, the lower jaw, and several teeth. These were uncovered by fossil preparator Andy Cowap and put on display in the Ulster Museum.

From 2007-9, while the Ulster Museum was undergoing refurbishment, the ichthyosaur was exhibited in Larne Tourist Information Centre.

Public right of wayEdit

The promenade, a footpath between the foreshore and the low cliffs at Waterloo, is a public right of way.
