So most of the Christmas decorations--at least the outside ones are down! and I got sidetracked again when I went into the garage to put the decorations away. Started to move fossil boxes around and found myself looking in the dang things...I was thinking some of this stuff needs to go in a case and started to photograph some of it and make sure the labels were with them. I've still got some work to do but thought I'd show you much of it...could be a few pieces on the other side of the garage but here's the bulk of what I have from Germany... This collection started many years ago and as I've never been there to collect personally my distant relatives immigrated from there and another good friend influenced me with her German collections so thru Gifts, trades and purchases here you go. Hoping there is something in here you havent seen before. File names have Genus and location. Some small vertebrates... An amphibian and similar sized small fish. Most of a dragonfly Some crustaceans from Solnhofen Some plants Some belemnites

Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 111: " Cup small, low and cone-shaped. The long and slender, non-pinnulated arms divide three to four times isotomously above the sixth to ninth primibrach in variable positions. The anal sack is slender and elongate and composed of several vertical rows of plicate plates. The stem is round with pentangular proximal elements." Of the 5 species described, P. zeaeformis has a relatively truncated cup. The anal sack has the appearance of a cob of maize (long and mostly curved). Identified by oilshale. References: W.

Regulaecystis pleurocystoides DEHM, 1932 Lower Devonian Emsian Bundenbach Hunsrück Germany Length 4cm -
Taxonomy from Fossilworks.org. Description (Südkamp 2017, p. 100): "The flattened theca is angular and trapezoidal in outline. The large angular anal field is positioned in the centre of one side of the theca (the anal), allowing it to be distinguished from the other (the abanal). The delicate plates are organized in large arcs across the abanal side. The peripheral rim is flat. The stem is very long. The body-oriented part consists of alternating simple and large collar ring-like elements. The more elongate distal elements are barrel-shaped. The long and slender uniserial brachiales are in the exothecal projections for food-gathering. Name meaning: Regula = Leiste, pleuro = to the side, lateral. Identified by oilshale.

Synonyms of Urasterella asperula are Protasteracanthion primus and Roemeraster asperula. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 127: "Urasterella is the most common asteroid in the Hunsrück Slate. The small disc is composed of a hexagonal central plate surrounded by five hexagonal radial plates, and a further ring of small plates. The small mouth is built of only triangular flat plates. The dorsal surface of the round narrow arms is composed of at least three rows of plates (radials, adradials and inferomarginals; the last were pushed upwards). All plates of the dorsal side bear paxillae with spines. The plates of the oral surface are arranged in two double-sided rows (ambulacrals ans adambulacrals). Mostly, only the large disc-shaped adambulacrals can be recognized, as the opposing subrectangular ambulacrals can only be seen by the wide-opened arm furrow. The adambulacrals bear a transverse ridge carrying long spines." Name derivation: Ur = old, Aster = star. Identified by oilshale. References: Roemer, C. F.

Chotecops is the most abundant trilobite in the Hunsrück Slate and due to the excellent preservation, often soft tissue such as antennae and legs have been preserved as a thin sheet of pyrite.

Loriolaster was a slow-moving low-level epifaunal detritivore-suspension feeder. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 132: " Loriolaster is related to Cheiropteraster and differs by the following features. The smooth skin forms a wide U-shaped area between the arms. The mouth frame consists of the mouth angle plates together with only the enlarged second ambulacrals. Loriolaster has wide ambulacrals and spoon like laterals. Their margin bears three rather short spines as well as one larger spine." Loriolaster mirabilis is more common than the more slender Loriolaster gracilis. Identified by oilshale.

The old name for this very common Ophiuroid is Taeniaster beneckei. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 135: "The mouth-angle plates are slender and abut to form a characteristic V-shape. The disc is constructed of oval-shaped scale-like plates held together by a reticulated pattern of granular skin. The interradial margin is concave or rounded and lacks marginal plates. The proximal ambulacral furrow is broad. The five arms taper evenly into long whip-like tips. A finely granular skin covers the dorsal surface of the arms. The ambulacrals are alternating, unfused and boot-shaped. The foot is only slightly longer than the top of the boot. The laterals are crescent shaped and ear-like. They bear up to five groove spines and five evenly tapering vertical spines, the oral-most one is the longest. The vertical spines decrease in length distally along the arms. Identified by oilshale.

Euzonosoma was a brittlestar genus that existed during the Devonian period. This E. tischbeinianum is from the Bundenbach slate of Germany. The slate was quarried for use in the roofing industry for many years and, at least in some parts of Germany, you can still see houses covered by Bundenbach slates. Unfortunately, roof-slate mining in Bundenbach came to an end in 1999. The fossil has been replaced by iron pyrite or ''fool's gold''. The brittlestar already started to become decomposed at the tip of the arms. Taxonomy from Fossilworks.org. Alternative combinations: Aspidosoma tischbeinianum, Encrinaster tischbeinianus. Description from Südkamp 2017, p. 132: " The quite large disc is composed of large and irregularly polygonal plates. The disc has a concave margin and is bound by blocky rounded marginals. They have in the middle part their largest size. The mouth-angle plates are small and stumpy and have a broad proximalgroove. The five elongate arms are the broadest just outside of the disc edge, taper strongly and end whip-like. The ambulacrals alternate over the midline and are rectangular dorsally. They form transverse ridges that are groove-like and, especially within the disc, deeply sunken. Orally the ambulacrals are boot-shaped. The tall laterals are blocky, rectangular and bear short groove spines." Identified by oilshale. References: Roemer, C. F.

Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 139: " Furcaster is a very abundant ophiuroid with opposing fused ambulacrals. These vertebrae are elongate and wing-like. The five narrow arms are high and taper to whip-like extremities. Each ambulacral pair has a pronounced median dorsal oval cleft. The ambulacral plates are essentially flat and plastron-like orally (plastron is the lower shell of a turtle). The round small disc is granulated. The mouth frame is petaloid and the mouth-angle plates are sub-triangular in outline. The ambulacral groove is open. The laterals are blocky to barette-shaped. They bear a tuft of vertical needle-like spines, and leaf-like groove spines." Lehmann (1957) listed three species: Furcaster palaeozoicus, F. decheni and F. zitteli. F. decheni is the largest and more robust than F. palaeozoicus. The disc incorporates about seven arm segments. Identified by oilshale. References: Stürtz, B.

This arthropod is a Marrellomorph, a clade of strange looking stem-group arthropods known from the Cambrian Burgess Shale and the slightly older Kaili Fauna in China (Marella), the Silurian Herefordshire Lagerstätte in England (Xylokorys), the Ordovician Basal Upper Fezouata Formation (lower Arenig, or lower Floian), north of Zagora in southeastern Morocco and the Caradoc (Upper Ordovician) in Bohemia (Furca) and the Devonian Bundenbach Shale in Germany (Mimetaster and Vachonisia). Marrellomorphs lacked mineralized hard parts, so are only known from areas of exceptional preservation, limiting their fossil distribution. The head shield has two pairs of long rearward directed spikes. Marrellomorphs possessed two pairs of antennae, one long and sweeping, the second shorter and stouter. The two dozen segments each have a pair of six segmented leg / feathery gill structures. There is a tiny, button like telson at the end of the thorax. The best modern guest is that Marrellomorphs are moderately evolved primitive arthropods descended from a common ancestor of the major later arthropod groups. Reconstruction of Mimetaster hexagonalis Reconstruction of another Marrellomorph - Marrella splendens - from the Cambrian Burgess Shale in Canada. A thorough re-investigation of Marrella splendens based on over 1000 specimens was recently published by D. García-Bellido and D. Collins: “A new study of Marrella splendens (Arthropoda, Marrellomorpha) from the Middle Cambrian Burgess Shale, British Columbia, Canada” in Can. J. Earth Sci. 43(6): 721–742 (2006). The overall form of Mimetaster and other Marrellomorphs suggests that it was a soft-bottom dweller. The wide carapace border would have prevented sinking into unconsolidated sediment. Mimetaster hexagonalis is the most abundant non-trilobite arthropod from this Lagerstätte. They are considered to live in groups of several individuals; two, three or even more species on one slab are not uncommon. A thorough reinvestigation of Mimetaster based on 123 specimens was recently published by G. Kühl and J. Rust in Paläontologische Zeitschrift, volume 84, number 3, 397-411.

What I Bought At The 2014 Ny/nj Fossil, Gem And Mineral Show
Shamalama posted a topic in Member Collections
So I have had time to sit and edit my pics of the fossils I purchased at the show this past weekend. Three Triarthus trilobites clinging to some branching algae. The association is what made me pick this piece up. It really looks like the trilos may have been feeding or trying to shelter on the algae. Seeing the little legs and antennae are really cool too. I could have bought a specimen with a larger trilobite but this piece just spoke to me. I kept the photos big so you could enjoy the detail... more in the next post.

Bundenbach Display At 2014 Ny/nj Fossil, Gem And Mineral Show
Shamalama posted a topic in General Fossil Discussion
Hi all! So I uploaded a bunch of photos over in the main thread regarding the 2014 NY/NJ Fossil, Gem & Mineral show but I wanted to post separately about the display of fossils from the Bundenbach area of Germany. The show had four display cases of fossils that were found in the slates from the quarries around Bundenbach with most of them being Crinoids or Starfish. The fossils were impressive but some specimens lacked tags telling you what they were. Interestingly there were a few fossils that were featured in a booklet that was displayed next to them. The author was set up as a dealer nearby and I got his autograph on a copy of his booklet. First off are pics of the cases: More to come...
