About Gunn Point Lobster Fossils

These fossil lobsters are Late Pleistocene to Early Holocene in age. It is believed that they were rapidly buried during events such as intense cyclones and the original exoskeleton of the lobster was replaced with calcium carbonate, strontium and iron creating a fairly hard mineral. They are found enclosed in hard, calc-lutite concretions formed during the lithification of calcareous clay around the encapsulated animal. These concretions are washed out of the fossil beds by aggressively heavy seas and onto the beach where they are then collected.
