Furca mauretanica MarellomorphDescription: This is a fine example of an Ordovician marellomorph known thus far as Furca mauretanica. The Marellomorpha are a small group of rare, primitive arthropods. The order was named after the Burgess Shale genus Marella (see my other offerings) and also includes Mimetaster (again, see my other specimens). The genus was first known from specimens found in Bohemia (Furca bohemica). In 2004 a new species was been found in the Upper Fezouata Formation deposits near Zagora, Morocco. The cuticle of specimens is typically preserved as a deep red or reddish-brown mineralization. Most specimens consist primarily of the cephalic shield and a trunk would project out between the posterior pair of extensions. Very few examples are offered, but new ones occasionally come to light. When this one was found several details not often seen were also observed: several pairs of walking limbs. The specimen split unevenly, with the posterior portion completely buried within the matrix. I asked if it could be resplit to expose the abdomen, but was told with this type of matrix such an attempt would be doomed to failure. It was with some trepidation that I requested that the lower half of the one side be sacrificed to have at least one half of the specimen completely exposed. This was done with great skill, affording the specimen seen here. I have been advised by the describer of the taxon that it will most likely be placed in a different genus, hence the quotation marks around the current genus.
