Looking for current information for fossils that aren't in all of my available references
Mediospirifer posted a topic in Questions & Answers
I'm putting together a bunch of entries for Collections, and I keep running across fossils for which I can't find some important pieces of data--like "Author Citation"! For example, I have one example of a tiny brachiopod listed as Cyrtina recta in my Linsley1 fossil guide. It doesn't appear at all in my Wilson2 guide, nor is it listed in Fossilworks. I did find it in Hall's Palaeontology of New York v. 43 as Cyrtina hamiltonensis var. recta. The plates used by Linsley are taken from Hall. Here's a set of photos of my specimen: Pedicle valve. 9mm x 5mm: Hinge side of pedicle valve: Brachial valve. 9mm x 5mm: Side view (Hinge at left): Now, Cyrtina hamiltonensis is listed in Fossilworks, as well as the Wilson guide, but that is a distinctly different shape. On this specimen, I'm looking for the correct Author Citation (Hall 1867?) and the current nomenclature. Example #2: Acrospirifer duodenaris, according to Linsley. Not listed in Wilson, Hall, or Fossilworks. Acrospirifer murchisoni appears in Fossilworks, but that's Lower Devonian according to Linsley (and isn't listed in Wilson or Hall, either). Here's some photos (9mm (if it weren't missing a tip) x 5mm): Pedicle, brachial: Again, I need an Author Citation and current nomenclature. Thanks for any help with this. I have more! 1. Linsley, D.
