I found this beauty yesterday in a gravel in central Poland, so it's an ice age gift from Baltic Sea or Scandinavia, Ordovician or Silurian in age. Any ideas? I'm thinking... maybe a billingsellid of some sort? I'm not good at Palaeozoic brachiopods.

These were collected at DSR during the TFF hunt last year. I am just getting around to processing the specimens. It's amazing that the diversity of bivalves I acquired was greater than the brachiopods! First, a picture of the site: Now the brachiopods (scale in mm):

Paleo Society access to Treatise on Invert Paleo
Wendell Ricketts posted a topic in Questions & Answers
Though I have a feeling I'm going to be embarrassed for asking what turns out to be obvious, but: I was hoping someone would be willing to give me a hand getting access to the 2007 Suppl. to Part H (Brachiopoda), Vol. 6 of the Treatise. The archives only appear to go back to 2010. Do Paleontological Society members not have access to earlier volumes? Thanks! Wendell -

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies

I found this apparently silicified pedicle valve as an erratic boulder. The age is unknown, but presumably Ordovician or Silurian. Provenance of Baltica (found in Poland, but in gravel parking lot). Any clues on the order? The rest of the shell is hardly preserved. Can you help to verify my anatomical identifications?

First trip of the year today to the "Fossil Gardens" at Paulding, Ohio. This is quarry spoil of mid-Devonian age, Silica Formation. There was not a cloud in the sky, and temps were relatively warm at 43 deg. F. I was the only one there for most of the day, and it was extremely peaceful. What a great day. Here are pics of some of the finds. These are "farm fresh" and haven't even been washed yet, but I did take time to polish some horn corals and get some acetate peels (couldn't wait). A large Cystiphylloides rugose coral.

Thanks to @minnbuckeye who gave me a site suggestion to an Iowa Devonian locality when I was on my way to the White River Formation of Nebraska, I was able to satisfy my palaeozoic fix this past June. Here are my finds (scale in photos is cm/mm): Orthospirifer cf. O. cooperi Strophodonta sp. Cranaena sp.
