The preservation of non-mineralized tissues in the fossil record is extremely rare. The Lower Devonian Hunsrück Slate of Germany has long been known for the preservation of non-mineralized tissues in pyrite but whether or not these remnants represent true soft tissues has been questioned. This is especially true for struetures visible only on radiographs that are too delicate for excavation by traditional methods. Here we report the discovery of well-preserved pyritized tube feet in six fully… 
Pyritized tube feet in a protasterid ophiuroid from the Upper Ordovician of Kentucky, U.S.A.
TLDR
A single specimen of the protasterid ophiuroid Protasterina flexuosa from the Kope Formation of Kentucky exhibits three−dimensionally pyritized tube feet, representing the first report of soft−tissue pres− ervation in an echinoderm from the type−Cincinnatian series.
New observations on some poorly known protasterid ophiuroids from the Lower Devonian Hunsrück Slate of Germany
Four genera and species of protasterid ophiuroids have been reported from the Lower Devonian Hunsrück Slate:Bundenbachia beneckei, Palaeophiomyxa grandis, Mastigophiura grandis, andPalaeophiura
Presumed postlarval pentacrinoids from the Lower Devonian Hunsrück Slate, Germany
TLDR
The Hunsruck Slate report is the first report of pentacrinoids from the fossil record and document that a Palaeozoic sister group to modern crinoids had similar developmental stages.
Taphonomy of diploporite (Echinodermata) holdfasts from a Silurian hardground, southeastern Indiana, United States: palaeoecologic and stratigraphic significance
Abstract A microbioherm-bearing hardground within the middle Silurian (Wenlock) Massie Formation near Napoleon, southeastern Indiana, United States is encrusted by the attachment structures of
Characterizing the branching architecture of drepanophycalean lycophytes (Lycopsida): an exceptional specimen from the Early Devonian Hunsrück Slate, southwest Germany, and its paleobiological implications
An exceptionally large and well-preserved drepanophycalean lycophyte specimen from the Early Emsian Hunsrück Slate exhibits branching morphology and architecture that suggest previously unrecognized
An edrioasteroid from the Silurian Herefordshire Lagerstätte of England reveals the nature of the water vascular system in an extinct echinoderm
TLDR
The first example of preserved tube feet in an extinct group of echinoderms is reported, from the Silurian Herefordshire Lagerstätte, UK, which is assigned to a new genus and species of rhenopyrgid edrioasteroid, HeropyrGus disterminus.
Paleoecology and taxonomy of Schoenaster carterensis, a new encrinasterid ophiuroid species from the Upper Mississippian (Chesterian) Slade Formation of northeastern Kentucky, USA
Abstract. Schoenaster carterensis new species, is an asteroid-like ophiuroid (Echinodermata) from Upper Mississippian (Chesterian) shallow-water carbonates in the Ramey Creek Member of the Slade
Redescription of the cyathocrinid cladid Codiacrinus schultzei Follmann, 1887 from the Lower Devonian Hunsrück Slate at Bundenbach (Germany)
Codiacrinus schultzei Follmann, 1887 commonly occurs in the Lower Devonian Hunsrück Slate of Bundenbach (Germany). Although this cyathocrinid cladid has been studied for almost 125 years, its
A NEW SEA SPIDER (ARTHROPODA: PYCNOGONIDA) WITH A FLAGELLIFORM TELSON FROM THE LOWER DEVONIAN HUNSRÜCK SLATE, GERMANY
TLDR
This new material shows that at least two fossil pycnogonids retained a telson, albeit with very different morphologies, and further supports the idea that a greater diversity of body plans existed among the Palaeozoic pyCNogonid taxa.

Aspects of the feeding biology of the brittle star Ophiura texturata
  • H. Feder

TLDR
Food analyses suggest that O. texturata is a potential predator of meiofauna, recently settled larvae, and small benthic macrofauna and may be more destructive to newly settled young than are specialized predators.
Mechanisms of Fossilization of the Soft-Bodied and Lightly Armored Faunas of the Burgess Shale and of Some Other Classical Localities

Lapworthura: A Typical Brittlestar of the Silurian Age; with Suggestions for a New Classification of the Ophiuroidea
TLDR
In the following paper an account is given of the structure of the Silurian Ophiurid Lapworthura miltoni (Salter), based upon a study of the fine series of this fossil in the Oxford Museum and of models made by the method described by one of us in 1901.
Comparative Morphology of Tube Feet Among the Asteroidea: Phylogenetic Implications1
TLDR
The results of this study demonstrate that the current tube-foot morphology model needs to be reconsidered, as there is considerably greater variation than was previously believed to be the case.
Early Paleozoic starfish

  • Environmental Science, Biology

  • 1951
TLDR
It would seem that starfish arose at a very early stage in the development of echinoderm stocks and arrived in a series of transgressions which began in the Tremadocian and persisted throughout the immediately succeeding beds.
A classification and phylogeny of post-Palaeozoic sea stars (Asteroidea: Echinodermata)

A revised classification and phylogeny at the family level and above are presented for post-Palaeozoic sea stars, with relatively greater emphasis on morphology and arrangement of ossicles and ossicular systems.
