sentences:  "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.
