Abstract
A new macrofossil genus and species from the Late Vendian of the Urals is described. Fossils are found on a bedding plane between the sandstone and mudstone and are represented mainly by casts on the sandstone surface. The casts are negative and flat-bottomed, covered with numerous, closely spaced uniform indentations and rimmed by a small, low, narrow, flat flange. This fossil can be reconstructed as a disk consisting of two layers. The top layer was less resistant and probably unstructured. The bottom layer was denser and was structured (either with a tuberculate surface or consisted of loosely packed spherical elements). Kuckaraukia multituberculata gen. et sp. nov. could be interpreted as a unitary organism or as a colony of motionless benthic organisms.
