Albumares instance of fossil taxon
Albumares brunsae is a tri-radially symmetrical fossil animal that lived in the late Ediacaran seafloor.  It is a member of the extinct group Trilobozoa.Occurrence
Fossils of the Albumares brunsae are known from deposits on the Verkhovka formation on the Syuzma River in the Onega Peninsula of the White Sea, Arkhangelsk Region, Russia. There are reports about Albumares sp. from the Rawnslay Quartzite, Flinders Ranges in the South Australia, but photographs or description of these fossils have not yet been published.Reconstruction and affinity
Albumares was originally described by Mikhail Fedonkin as a free-swimming scyphozoan jellyfish. The branched furrows on the fossil were interpreted as imprints of a system of internal radial canals and tentacles along the outer margin of the fossil, with the three oval ridges described as imprints of mouth lobes or gonades.Later, with the discovery of the closely related Anfesta and with their seeming affinities to Tribrachidium, Fedonkin appointed these animals to the Trilobozoa , an extinct group of the tri-radially symmetrical coelenterate-like animals that only superficially resembled cnidarians. Originally, Trilobozoa was established as a class in the phylum Coelenterata, but since Coelenterata has been divided into two separate phyla, Cnidaria and Ctenophora, Trilobozoa itself has been promoted to the rank of phylum.According to the latest research, Albumares was a soft-bodied benthic organism that temporarily attached (but did not adhere) to the substrate of its habitat (microbial mats). This fossil typically displays as an imprint of the upper side of the animal's body, and often some elements of its internal structure can be discerned. The branched furrows on the fossil are imprints of radial grooves on the surface of  the animal, while the three ridges in the central part of the fossil are imprints of cavities within the body. Presumably, this system of grooves and cavities could be related to the collection and digestion of food particles.
