Maculicorpus is a genus of fossil placozoan from the Middle Triassic of Germany, and the first placozoan known from the fossil record. It comprises a single known species, Maculicorpus microbialis.[1]
Discovery
[edit]Maculicorpus is known from a microbialite bed discovered in the Troistedt Quarry near Weimar, as part of the Meißner Formation. The microbialite has been dated to the late Anisian to early Ladinian.[2]
Description
[edit]The specimens referred to Maculicorpus appear as flat patches, brown to ochre in color, varying between 1 mm (0.04 in) and 5 mm (0.20 in) in diameter. The outline is irregular and varies in overall shape from circular to elongate, fan-shaped or multi-lobed. The holotype, 4.5 mm (0.18 in) in length, is constricted in the middle, appearing as an aggregate of a larger, irregularly rounded portion and a smaller elliptical one.[1] Maculicorpus is larger than any modern-day placozoan.[3]
