CAIRO — A team of Sudanese geologists from the Regional Geology Department of the Sudanese General Department of Geological Surveys at the General Organization for Geological Research recently unearthed a marine sedimentary formation in Sudan dating to the Cambrian period. They have named it the Al Barda and Abu Talih formation.
The General Organization for Geological Research explained in a statement published on its Facebook page on Sept. 28 that “the age of the sedimentary formation has been determined thanks to a fossil belonging to the phylum of sponges called Archaeocyatha, which are an extinct reef-building species that live in marine environments. These species existed in the early Cambrian period but eventually became extinct, meaning that they date back to over 500 million years ago.”
