Bergaueria elliptica Orłowski et Żylińska, 1996

Description.-The holotype and only specimen is oval in shape with a furrow along the axis. A delicate striation parallel to the furrow covers the surface; the ends of the structure are wrinkled. The border of the structure is clearly delimited, probably corresponding in its course to the irregularly waved surface of the bedding plane. Length is 65mm width 55mm, depth 20mm. The wrinkles may be results of deformation of the burrow preceding diagenesis of the sediment. Convex hyporelief.
