Locally, graptolites are very common in the Maquoketa/ Ordovician rock. They present themselves as 2 dimensional creatures on certain bedding planes. Below the Maquoketa is our Galena. It has graptolites but uncommon. Again, they present themselves as 2 dimensional. The "unknown" specimen from the Galena, presented today, is obviously 3 dimensional and I venture a guess that it is a Graptolite. But I thought I would seek opinions in that I have seen thousands of local graptolites but never one that is 3 dimensional. Could it be something else??
Hi all, I don't know much about brachiopods beyond general recognition. Since I found that little unidentified echinoid(?) I have decided to prep some of the loose brachs that I found on a recent trip to Fillmore Co., MN. The complete brachiopod here appears to have been attached to another brachiopod shell. So here are my questions. 1. Can anyone identify the brachiopod? (I am assuming they are the same species) 2. Would this be considered an unarticulated brachiopod? 3. I haven't finished prepping the interior of partial brachiopod. I wasn't sure what to call it so I referred to it as the host shell in the photo. It has what almost looks like an open crack. Any idea what might have caused this? There are little black specs surrounding it. Could this have been caused by another brach pedicle? When I was prepping it, it kind of reminded me of a burrow lined with tiny fecal pellets - but my imagination does tend to get the best of me. As always, thanks for your help! @minnbuckeye @Bev @Tidgy's Dad
Ordovician Galena Formation: Stewartville or Prosser member Fillmore County, MN For Scale Rock Rock for scale Trilos for comparison: Raggedy Man and Laura are over here hunting this weekend and I was showing them this interesting rock I found with lots of crinoid stems and parts that I picked up a couple of days ago. Any idea on what species of trilo this is? Thanks for looking!
It all started with Raggedy Man coming over from Wisconsin to fossil hunt SE Minnesota Bluff Country on Labor Day weekend camping out by the trout stream in my yard. He was after the other parts of the rare trilobite he had found here on his last hunting trip. And he FOUND a large part of it! I will leave it to him to post the picture. :-) The next day Fossilized6s showed up to hunt and we had a blast hitting various sites, I got tired and they went out until dark. I am posting some of the highlights of the trip, the full trip and lots more pictures are here: http://www.bluffcountryfossils.net/blog/labor-day-2016-with-tff-friends/ I had salmon, rebaked potatoes, and garden beans on the grill for them when they got back as Charlie had set up his tent also. The next day PapaDave joined us! R-L: Raggedy Man, PapaDave, and Fossilized6s comparing notes and where to go. After pouring through some of Sloan's book (THE BEST for Minnesota) we decided to head out and hunt some sites off of my new Forestville Fossil Hunting sites map and see the famous Rifle Hill Quarry. All three of these guys were focused on trilobite hunting, so I set them up with the most likely trilobite sites. Rifle Hill Quarry is famous in the fossil literature from the 1800s, so we just had to see that. My thinking is that in the 1800s they were excavating through the shale layers at the top of the quarry which is very fossiliferous, not so much today. We over-viewed a couple of sites and then hit 3 sites, and that is when Charlie came up with a trilobite! "Finding this makes the trip worthwhile!" he said. :-) Then we went to a site where I had found a trilobite last time Raggedy Man was here and had given it to him. PapaDave found this beauty! Old Bev was getting tired by then, so I convinced them to go to the premiere gastropod quarry in Minnesota - my personal favorite. I wish I had some pics of the finds, maybe they will post them in replies, but Raggedy Man came up with a nice big Maclurites sp. (an index fossil for the Ordovician) and PapaDave came up with some beautiful cephs and gastropods. Here are several of PapaDave's finds from that hunt: Cephalopod Continued...
