ACCESS: ♦♦♦♦ – There is a good car park and a short walk to the shore, this location is easy to find and is north of the lighthouse at St Mary’s Island.

FOSSIL HUNTING

Fossils at Seaton Sluice are found mostly in the rocks and shale on the foreshore. The grey coloured non-marine rocks contain plant remains and bark, and the sandy orange coloured rocks contain the marine fossils such as corals and bivalves. There is plenty to be found here.

Fossil bark is also quite common, and pieces of bark can be collected along the foreshore loose. We recommend splitting the shale as often, you will find fossils inside.

SAFETY

Common sense when collecting at all locations should be taken and knowledge of tide times should always be noted. The tide can easily cut you off at Seaton Sluice so please double check tide times. The rocks can also be very slippery so please take extra care.

EQUIPMENT

The best tools to take at this location are a chisel pick and safety glasses. These are ideal for splitting the rocks, which contain fossils. You will also need plenty of paper to wrap your finds, as some of these can be fragile, especially the plant remains.
