Does anyone have any idea what kind of brachiopod this could be? I'm sure we can't identify the species, but maybe the family or even the genus? Carboniferous Serpukhovian Bear Gulch Montana

Hi I broke open a rock in southwest Wisconsin, and I found this collection of brachiopods. Can anyone try to tell me what genus they are? Each of them are around 2 cm long.

I've had some difficulty narrowing down the identity on some assorted brachiopods. The diagnostic features may not be preserved but I figured I'd post them here to see if anyone knew. @Tidgy's Dad Any ideas? The first is a single large valve from the Warsaw Formation in Fenton, Missouri (The old Meramec Bridge site). I've been able to track down most species reported from here and identify everything else but this one is harder. The wear doesn't help. The second are a couple o Echinoconchidae valve casts in chert from a creek in Lincoln County, Missouri. It

Request for feedback on fossil field guide visual layout
pefty posted a topic in Questions & Answers
I'm working up a series of fossil field guides for various formations. I'd like to provide a visual indicator of which fossils are rare, which are common, and which are abundant, without getting in the way of the visual layout of the fossils & identifying information. The complete set of categories I am working with is {Abundant, Common, Rare, Very Rare, Common to Abundant, Rare to Abundant, Rare to Common, Present, and Questionable}. Has anyone seen a good way that a field guide of any kind has provided such a visual indicator as a page-wide element of visual layout? Attached is my first- 13 replies

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 com

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?

This is a plate of Productus brachiopods with spines collected from marine sedimentary brown-red clay shale, which sits on a bed of breccia limestone. Location is slope above rest-stop on east side of Highway 89 N about two miles north of Riceville Rd. in central Montana. Was collected on Jan 21,2019. Prep work was done by collector David C. Powers.
