Collections of dissociated echinoderm sclerites from the Muschelkalk of the Mecsek Mts yielded different crinoid assemblages. Because they are strongly resembling crinoid assemblages from the Muschelkalk in Upper Silesia in composition and stratigraphic position, the zonal scheme of 4 crinoid biozones established for the Muschelkalk in the eastern part of the Germanic basin can be transferred to the Mecsek Muschelkalk. These biozones are: Dadocrinus zone, acutangulus zone, dubius zone, silesiacus zone (Lower Anisian to Lower Illyrian). The same community sequence or zonal scheme corresponding to a similar vertical facies sequence from soft grounds to shelly and firm grounds is observed in distant sections of the western Tethys realm during Lower Anisian through Lower Illyrian times. Significant crinoid assemblages were covering wide areas of the western Tethys during Early Middle Triassic times.
