ziggycardon Posted May 31, 2023 Share Posted May 31, 2023 Hi everyone, I recently purchased a collection from a retired fossil collector. Including in this collection was a box with Brachiopods from the Eifel region. Unfortunately it is harder than expected to ID them all. So here is the first batch of photo's of Brachiopods which I all believe to be Spiriferid. 1) A couple of small Spiriferid brachiopiods which seem to be from the same species: After some google searching and comparisons my best bet is "Hysterolites hystericus" 2) A larger well preserved Spiriferid Looks like a Cyrtospirifer sp. to me 3) Another larger and well preserved Brachiopod: Pretty sure this is a "Spinocyrtia ostiolata" 4) A larger Brachiopod Another Cyrtospirifer? 5) A larger Brachiopod (same species as nr 4) Another Cyrtospirifer? 2 Interested in all things paleontology, geology, zoology, evolution, natural history and science!

ziggycardon Posted May 31, 2023 Author Share Posted May 31, 2023 6) Quite an high arched one, not really finding any nmatches for it. Could it also be a Hysterolites hystericus? 7) Extremely high arched one (almost pyramid shaped) Closest thing I could find is "Cyrtina heteroclita" 8) Not sure about these ones, Arduspirifer?

ziggycardon Posted May 31, 2023 Author Share Posted May 31, 2023 9) A weirdly pressed or Pathological one, also Arduspirifer? 10) another Spinocyrtia ostiolata? 11) And the last ones from this batch, some Brachiopods which I suspect to be Undispirifer undiferus 1 Interested in all things paleontology, geology, zoology, evolution, natural history and science!

Tidgy's Dad Posted May 31, 2023 Share Posted May 31, 2023 Just a side note, Ken, but spiriferid is an informal name for the group, so should not be capitalized, One uses capitals for the formal clade such as Spiriferida. It's the same as saying trilobite or Trilobita. Spiriferids are very hard without knowing the exact location or statigraphy, but I''ll have guess based on the hope that they may come from the same location or near to wherever the other brqchiopods you posted were found. 1) I think the first photo may show two species, the ones with the wider hinge lines / wings could be Arduspirifer supraspeciosus. The other, more rounde ones, where the wings look to be in the midline of the shall might be Quiringites sp. The two are often found together. 2} Could be Cyrtospirifer, but would probably make it Frasnian or Famennian if found in Germany. 3} Yes, I reckon Spinocyrtia ostiolata is a good id. These are found in the Eifelian of the Eifel region. 4 and 5) Could be another species of Cyrtospirifer, there are a lot and they can be quite different looking, 6) No, but I don't know what it is, maybe a species of Cyrtinopsis? 7) Yes, lovely Cyrtina heteroclyta. Note the correct spelling of the specific name. It is a spiriferinid, not a spiriferid. 8) Maybe Arduspirifer. 9) Could be. 10) 11) I'm going with Rhenothyris renitens for these. Lovely fossils, mate. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Will make photos of all the other species in the coming days 1 Interested in all things paleontology, geology, zoology, evolution, natural history and science!
