Abstract

A new lingulate brachiopod assemblage has been found in the early Middle Cambrian Týřovice Greywackes of the Skryje-Týřovice area (Central Bohemia, Czech Republic). A new species, Lingulella agaue sp. n., a minute indeterminable lingulid, a ceratretid Almohadella braunae Streng, 1999, and an acrotretid Treptotreta? sp. have been ascertained in the fauna. Four species in one bed is the most diverse lingulate fauna in the area. Associated faunas indicate a shallow marine nearshore environment with a simple trophic structure dominated by an eoorthid Pompeckium kuthani (Pompeckj, 1896), and a few other epibenthic low suspension feeders, as well as uncommon scavengers and browsers. The presence of Almohadella braunae Streng, 1999 is the first incidence of a ceratretid within territory of the Perunica terrane.
