Thirteen species of fossil sponges from limestones of the Garra Formation of late Lochkovian-early Pragian age are described, and their distribution within the lower part of the limestone is recorded. The lithistid genera Garraspongia and Brianispongia, and the calcisponge Radiothalamos are described as new, together with the type species of these genera. The new species Devonospongia garrae, Isispongia monilifera and Astylospongia tarda are also described.--Modified journal abstract.
