As I've been cataloging my Devonian finds, in my research I've come across both mucrospirifer and mediospirifer. I'm not certain of the characteristics that would set the two apart. Can anyone provide some clarity or point me towards a resource that could?

Since we both had the day off, my daughter and I spent a couple of hours at the Deer Lake site (Schuylkill County PA). It was a beautiful sunny day in the mid 50s! A good start to this years fossiling adventures...

Took a few college friends out to the Deer Lake region today. Was the first time fossil hunting for one of them and the first time finding non shark teeth for another. Checked out a couple different outcroppings, everyone took a few things they enjoyed. Here is my haul from the day (feel free to correct if I miss IDed)... 1x Eldregeops 3x Mucrospirifer 1x Leptodesma

Hello fossil experts! I have a background in geosciences but know very little about fossils. I found the below fossils along the Rouge River near Detroit (Michigan). Doing some quick research, I think these are from the Mucrospirifer order, probably of the Thedfordensis species. Do you agree? (longest is about 1.5 inch / 4 cm) The thing I'm most puzzled about is from what strata they are from. The interweb tells me these Mucrospirifer here are mostly from the Middle Devonian (Antrim shale, Traverse Group), while the location where I found these (as well as all of the upstream terrain) has younger bedrock, from the early Carboniferous/Mississippian (Coldwater Shale). This Coldwater Shale is a pretty thick deposit so a river/glacier can not puncture it easily. I used the Bedrock Geology map from www.esrs.wmich.edu/mgs/webmgs/migis.html Thank you very much for your insight! Jazz

This looks similar to Mucrospirifer, especially the growth lines, but the interarea doesn't look right to me. I thought perhaps Brachyspirifer, but not sure if they exhibit growth lines like this. This is from the Middle Devonian Bell Shale. Scale in cm/mm. @Tidgy's Dad

After Monica's recent post looking for HH IDs I'm prompted to solve a couple uncertainties of my own from that spot, if anyone can help me... This coral was labeled 'Favosites (poss. alpenensis)'... Can anyone confirm or suggest a better fit? I don't know what all the species of Favosites are at that place but I know there are more than one. Second, I know there are 2 types of Mucrospirifer, one being more elongated than the other. I believe I have some of both here but some seem ambiguous. Are there any surefire distinguishing features of either species other than the (possibly variable) elongation?

I know this is a long shot, but I was hoping someone could identify these two fossils I know almost nothing about. Back in the 1970s and 1980s, my mother owned a lapidary and rock shop in Southern California. Her customers would sometimes give her samples of rocks and fossils they had dug. I believe that is how she got these. When she retired she packed everything up and moved it to her home. I inherited some of it when she passed away. That’s about all I know of them. The brachiopod looks like it might be a Mucrospirifer sp., but I really don’t have any idea about the ammonite. Perhaps something from the Goniatiida order? I know some of you will want to know the rock formations they came from. I’m not a geologist so I don’t really know. I can only tell you I found them in the Cardboard Box member of the Spare Bedroom formation, within the Old House group. (I thought I might apply to register those names with the USGS Geologic Names Committee).
