Two weeks ago, I traveled to Central (Devonian) and SE Iowa (Mississippian) for a little fossil hunt. It was very successful and I will complete a trip report soon. In the meantime, it would thrill me to understand a few unknowns from the trip. First of all, the Mississippian, Burlington Formation: 1. and 2. 2. is a brachiopod that I could not find in the lists of brachiopods from the Burlington Formation. 3. There were many of these present in a certain layer of rock. Very circular with longitudinal striations.

The other day I went on a annual trip to a quarry in Iowa. Givetian age rocks. Finds were few this time around, for me at least. This was my best find, although not perfect or complete, still a nice example. It was tricky to prep as I didn't want to destroy the reddish- mauve brachiopod contrasting nicely with the caramel colored E. noorwoodensis. Thanks for looking!

Hi, I have three bones today that need your help to ID. They were found on Iowa River's alluvial deposits. Thank you!

Fossil Plants From Cave Deposits, Near Pella, Marion County, Iowa lepidostrobus Sp. Brongniart- arborescent, 310 Mya old, Club Moss locality, Pella, Iowa Formation, Pella Beds Age Pennsylvanian The Lepidostrobus is the generic name for the cones of arboresent lycopsid. It corresponds closely in structure with the fertile spike of the living Selaginella. The spore-bearing leaves are attached to a central axis in a crowded spiral arrangement, and their outer ends curve over so as to form an imbricated, diagonally arranged pattern, resembling that of the stem i

I read a lot of fossil hunting reports on here, but I don’t post many. I think it’s primarily because it is usually many, many months after I have gone when I finally get everything cleaned up, ID’d and take photos, etc. It just seems too after the fact to me at that point, haha. But this time, due to a wonderful “tour guide” we had, I wanted to get something posted in a relatively timely fashion. Because of that, I haven’t had time to do a lot of research I need to do on specific ID’s but luckily I’m somewhat familiar with most of what we found to make at least an educated guess.

These two finds are stumping me a bit. Both are from the Maquoketa Fm (Upper Ordovician) of Iowa. The first one initially struck me as a 3D graptolite, but it could be a crinoid stem. I couldn't get a good photo of the cross section, but it is rectangular.

This is a tusk I recovered from a river sand bar in Iowa 24 hours ago. The tusk was in somewhat damp sand. It started to degrade right away once it was unearthed. I wrapped the tusk in a towel but it did dry out a bit. I got it home about 5 hours later and re-wrapped it in damp towels. I am writing this post to spell out my plan based only on reading some other posts but not based on any experience. I would appreciate any advise. What am I missing or doing wrong? -Add many zip ties to hold tusk together. Leave crusted-on sand for now. -Wrap with damp towels

I am undecided if this is fossil or dendritic deposits on a rock. It is from Keokuk limestone, Mississippian.

I found this today in the yard while doing some light soil work. No idea where it may have come from. Thinking it might have come up from the frost over the years. Look like sinew or even fat tissue when I saw it buried. After bringing it up and cleaning it up thought it looked like a giant arrow head. Then it even appeared to look as though in the pointed portion on the item it had what looked almost like growth plate lines like we have in our bones. The stub end looks a lot like a joint or knuckle of some point. We are located near the Iowa and English river basin's In Iowa. Any help would b

Another post regarding a specimen I found posted on a Facebook fossil ID page - which no one in the group can ID. This was found in a river in Iowa. Most of what is found in the area is Pleistocene to modern. My first though was part of a turtle shell attachment point? But I am stuck.

Hi, I found this in Pensylvannian glacial till around a reservoir. It’s about 12” long by 5” in diameter. There are coal seams nearby. I think it’s a lycopod part of some kind but it doesn’t match most of the pics I’ve seen. Can anyone tell me more? I’m curious about the layered appearance. I don’t think it was in its original location as it was stacked on a big rock with other specimens. I left it in place due to regulations. Would have liked to keep it! Thanks!

I recently bought this jaw and was wondering if someone can shed some light on it. Seller gave some info on it, but when I received it it’s a little different than expected. Seller states it was found in Iowa. It also seems very light if it’s fossilized, I have no experience with fossil bone so I’m not sure what to expect. Any help is appreciated. Thanks

I found this fossil in Devonian rock in Johnson County, Iowa. I think it is a fossil of a placoderm fish, and I think it has a "fin" next to the quarter in the photo. The fin would be coming out of the placoderm plate at a perpendicular angle, which would make sense, but I have never found a fin before. I will attach a close-up photo of the "fin" below. Am I on the right track or is this something else? Thank you! Ben

I discovered these two rollers in Fayette County , Iowa in the lower Maquoketa, Ordovician. This location is well known for Anatophrus borreaus trilobites. Though the next lower formation changes abruptly to almost 100% Isotelus. Did I find one of each? Rollers make IDs tough on me. Then as long as you "trilo" experts are looking, can you ID the trilo-bits 1,2 and 3 in the next picture? Thanks for helping!!

Due to an upcoming order from our Governor to stay at home, I took the opportunity to fossil hunt last Sunday afternoon before it begins. The ground was white with an unexpected snowfall overnight when I left the house but soon melted. My goal was to look at road cuts for rock slides from the winter's freeze thaw cycle. Digging and splitting would be tough with frost still in the ground. The first spots searched were Ordovician, Galena. Here are a few representative fossils from the Galena of SE Minnesota: From there, I slipped over the border

My wife found this jaw bone on a river sand bar in central Iowa last fall. I think it is a sloth jaw but not certain. The smallish size is what gives me a little bit of doubt. I have not found anything else other than a sloth that fits. Am I missing something? Thank you!

Hey group. I hope you're not getting tired of answering all my questions. Because...... I am requesting your expertise in a few more crinoid identifications. The information (as listed) I have on this specimen is it a Devonian Crinoid Flower from an estate sale collection from the early 1960's. It's listed(?) find location is Iowa, USA. It was originally purchased from Ralph E, Mueller and Son Phoenix, AZ in the early 1960's and was displayed in their store for several years until being sold. Help please!

Collected in northeast Iowa which is part of the Driftless, very rugged with lots of streams and flooding that cut away the earth. Most fossils here are Ordovician. Most are limestone of the Galena Formation. HOWEVER, this area is a hotbed for mammoth and mastodon teeth and bone finds that the locals call "dinosaur bones". That said, there is an area recently rumored to have a lot of "dinosaur bones" just 30 miles southeast east of Spring Valley, MN on the edge of Iowa. No one wants to talk about it for fear the government is going to come and confiscate their finds. Posting for a

Hello fossil folks! I am going through my bone collection from last season and would like to identify the five bones pictured. The most interesting one to me is #5 as I believe it is too long to be a horse. Perhaps camel? All of these bones were collected from a river in central Iowa. So far, my wife and I have found prehistoric bison, horse, sloth, mastodon and mammoth bones from the pleistocene period. I am pretty sure these are either Metacarpal or Metatarsal bones. Sorry but I do not have a metric scale for the pictures. I have labeled the bones 1 thru 5 and noted each
