Sitia Global Geopark is on the easternmost edge of Crete, in the Municipality of Sitia. It has abundant mammal fossils of the Pleistocene epoch (2,588,000 to 11,700 years ago, last part of the Quaternary Period). The discovery of three fossils of the elephant-like Deinotherium giganteum at the site, its extensive cave systems and the palaeo-shorelines around Zakros are unique to Crete. Abundant karstic structures on the limestone environment of the site constitute its most salient characteristic. More than 170 caves and many gorges have been found in the area.
