This ichnofossil consists of an accumulation of tentaculites, probably of the genus Styliolina. Dr. M. Poschmann (General Directory of Cultural Heritage Rhineland-Palatinate in Koblenz) mentioned in a personal communication that accumulations of tentaculites / styliolites from the Hunsrück Slate are known, also in the State Collection in Mainz such pieces are found. Tentaculite accumulations can occur in quite different forms, among them those which are probably to be interpreted as coprolites due to their shape and rather irregular arrangement. Cylindrical assemblages of tentaculites / styliolines with orientation of the shells transverse to the long axis (as in this case) are also known and have been interpreted as agglutinated housing tubes of polychaetes worms. At the University of Bonn a diploma thesis on this topic has been done in 2010 - unfortunately no results have been published until today. Identified by Dr. M. Poschmann.

Normally this sandstone is filled with bivalves and snails of various species in the loosely consolidated. The "rust" color almost always is a biological marker in this sandstone. All of the bivalves and gastropods have that coloration. This specimen was found when a smallish piece of sandstone was separated in half. This half has the "head" I think, the other part has most of the cast of the body (this whatever it is, is bilaterally symmetrical). The only paper I have does not mention annelids. Anyone want to take a guess what this is, sending it to a "real" paleontologist to get an opinion.

I would like to know whether this specimen in a Mazon Creek nodule is the polychaete worm Esconites zelus (incomplete, distal part of the body - as suggested by the "tail-like" structure at one end) or a millipede (or something else)? (I also considered Acanthotelson, but there are too many segments in my specimen). The legs are comparatively long, but badly preserved (and only on one side of the specimen). I know this specimen is no beauty. The total length of the fossil is 20 mm, the width (without legs) about 2,5 mm. Picture 4 shows the counterpart (without legs). Thanks, araucaria1959
