摘要

Two cone-shaped Early Jurassic (Late Pliensbachian) chitino-phosphatic fossils are described from a clay pit near Buttenheim (northern Bavaria, Germany). The chemical composition and microstructure of their black wall corresponds partially with that of Palaeozoic presumed scyphopolyps like conulariids and the genus Byronia MATTHEW, 1899 and show similarities with the circular periderm tube of the modern Stephanoscyphus. A possible relationship to other chitino-phosphatic fossils, like inarticulate brachiopods or anaptychi of ammonites, is excluded. The presence of growth-lines on the tube surface further excludes an interpretation as remains of ecdysozoa (e.g., arthropods). Accordingly, the new findings are assigned to scyphozoan polyps representing a new family Liaporidae, with Liapora neubigi n.g. et n.sp. The new Early Jurassic scyphozoan genus Liopora shortens the gap in the fossil record between the so far youngest known conulariids from the Late Triassic and modern thecate scyphopolyps (Coronatae).
