| Summary: | Unique finds of a fossil discinid with a bodily preserved pedicle are described. They prove that soft parts can be pyritised in the Hunsrück Slate. The generic assignment of Orbiculoidea mediorhenena FUCHS, 1915 is in doubt. A reconstruction has been attempted. |
| Reaction 1: | In the Treatise on Invertebrate Paleontology, revised Version of Part H: Brachiopoda, Volume 1: Introduction (1997) the find of this brachiopod with soft parts and bodylike preserved pedicle is mentioned and visualized with a photograph (A. Williams, M.A. James, C.C. Emig, Sarah Mackay and M.C. Rhodes in the chapter: Anatomy on the pages 62 and 63). |
| Reaction 2: | M. Otto has drawn one of the both finds in the Paläontologische Zeitschrift 74, 2000, 79-89 in his article: "Supposed soft tissue preservation in the Hunsrückschiefer (Lower Devonian, Rheinisches Schiefergebirge): the example of brachiopods" and informed about his new investigation. He confirms, that the assignment to the genus Orbiculoidea is doubtful and interprets the find as a trace fossil accidentally brought into contact to the brachiopod shell. |
| Reaction 3: | BARTELS & POSCHMANN (2002) described in "Linguloid brachiopods with preserved pedicles: Occurrence and taphonomy (Hunsrück Slate, Lower Devonian, Kaub Formation, Rhenish Massif, SW Germany"), in Metalla, Nr. 9.2, pp. 123-130, three further lingulid brachiopods with pedicles preserved. The first ones, from discinid brachiopods, were discovered by SÜDKAMP. OTTO (1998, 2000) interpreted these as a coincidence of unrelated structures. BARTELS and POSCHMANN concluded, that conditions favourable for the preservation of brachiopod pedicles were present in the Hunsrück Slate and that the interpretation from Otto of the discinid pedicles is improbable. |
| Reaction 4: | In the article: "New finds from the Devonian of the Hunsrück", M. POSCHMANN (in: FOSSILIEN 6/04) presents two important slabs with fossils. One of these are, after the discovery discinid brachiopods with a preserved pedicle by SÜDKAMP (1997, the first lingulid brachiopods in such a preservation from the Hunsrück Slate. |
| Reaction 5: | Baliński & Sun (2013) in their paper "Preservation of soft tissues in an Ordovician linguloid brachiopod from China" (Acta Palaeontologica Polonica 58(1): 115-120) describe the first pre-devonian linguloid brachiopod with a three-dimensional, pyritized pedicle. Interestingly, the pedicle is provided with a terminal short bulb (as in Südkamp 1997). As an example of specific preservational conditions after the Cambrian Südkamp (1997) is mentioned. |
