Radiolarian fossils are here reported from clasts of pelagic chert in the Quaternary gravel beds along the River Euphrates in and around the Ghanem al-Ali, Ar-Raqqa, Syria. The gravel beds generally include clasts of silicified rock, felsic tuff and tuffaceous sandstone, rhyolite, quartzite, chert, plutonic rocks, metamorphic rocks and basalt. Minor amounts of sandstone, mudstone, limestone, gypsum etc. may also be present. Sixty-one percent of the chert samples include abundant radiolarian fossils of Middle Jurassic to Early Cretaceous age. This is a clear indication of the existence of Middle Jurassic to Lower Cretaceous radiolarian chert in the eastern Taurides, upriver regions of the River Euphrates. Such exposures have not previously been reported in the eastern Taurides.
