Material.— One tooth (MWGUW/Ps/13/2) from the upper Tournaisian, Czatkowice, sample A.
Description.— The tooth of Jalodus from Czatkowice has two cusps fairly well preserved, but the third cusp is broken at the base and reveals a relatively large pulp cavity. The base is slightly abraded and therefore the size and shape of the orolingual button is unknown.
Remarks.—Generally, the tooth is similar to those called by Ginter (1990: pl. 1: 7–10) Phoebodus (now Jalodus ) australiensis Morphotype 2, found in a neptunian dyke at Dalnia, Holy Cross Mountains, Poland, associated to a mixed, latest Famennian to earliest Tournaisian conodont fauna. Comparable teeth are also known from the Famennian– Tournaisian boundary beds of the Dapoushang Section, China ( Wang 1989: particularly pl. 29: 3, as Cladodus sp. ). Because the typical specimens of Jalodus australiensis (Morphotype 1 sensu Ginter 1990) are usually found lower in the Famennian ( Palmatolepis expansa –Early Palmatolepis praesulcata conodont zones), the tooth from Czatkowice may represent a younger, only slightly different, species.
