Calcari ad aptici e Saccocoma Formation
Geologic formation in Camponocecchio, Italy
From Wikipedia, the free encyclopedia
The Calcari ad aptici e Saccocoma Formation,[1] also known as the Saccocoma Formation (known in English as the Haptic limestones and Saccocoma Formation), is a geologic formation in Camponocecchio, Italy that dates back to the Tithonian (152 Ma) - it was first identified in 1976/1980,[2][3] and was named in 2002.[1] It was probably a marine shale due to the fossil content.[4] Fossils found there include ammonites, cnidarians and the ichthyosaur Gengasaurus, discovered in 1976.[5] Many of the fossils found in this formation are housed at the Spaelaeo-Palaeontologic Museum in Genga.
