I found this partial curved cephalopod at the famous cephalopod beds (Maquoketa Fm, Upper Ordovician) at Graf, Iowa last year. It is the only non-Isorthoceras cephalopod I have found from here in my several trips. The only other cephalopod I have seen described from this site is Beloitoceras, but I don't believe that is what my specimen is. Has anyone come across anything similar? Thanks for your thoughts.

Found this tooth in Central Iowa in the river. We have had a drought for 2 years, and our rivers are very low, which let's my friends and I find artifacts, rocks, and fossils in the river that we normally couldn't access. We find lots of bison teeth, but this tooth seems different. Sorry, no metric ruler. 2.54 cm in an inch.

Yesterday found me exploring multiple Galena/Ordovician road cuts in northern Iowa. Finds for the most part were good but just the common fossils found in this rock formation. However, one rock I examined contained a positive and negative relief of something I do not recognize. Hopefully someone can put an ID to these pictures!!!!!! Positive front Positive back Positive from the side negative imprint Both positive and negative together

Hello, I found this possible fossilized bone in the creek on my friends 26 acre Farm in poweshiek County, Iowa. The farm is located on Glacier land. The farm has very sandy soil and large Hills that slope down to the creek. I have found many easily identifiable fossilized bones such as jaw, femur, pelvic and teeth but this one looks very odd but seems to have the correct pores and texture. Any help will be appreciated thank you.

Hello I'm new to the fossil forum and hopefully I provide enough information. I found this fossil egg looking Rock in poweshiek County Iowa. One of my close friends owns a farm and we have been finding several possible fossils in the creek and near the surface on the hillside. The farm is 26 acres and located on Glacier land which is very Sandy with steep hills down to the creek which starts about two miles away from me natural spring and never dries up. This one was found about two feet below the water, sand and mud. It appears as if the little rascal was hatching, that is if it's an egg. Thank you

Last Sunday, our rock club took part in Morrison, Iowa’s Pioneer Craft Fair, with a goal of educating the children in various topics of paleontology and mineralogy. I took the opportunity to discuss ancient sharks and show a variety of specimens that I have accumulated. Even the adults had a hard time grasping that one of my display of teeth were actually from Iowa. The children then had the opportunity to split open some “rocks” revealing sharks teeth within. It was a hit and I enjoyed it more than the kids!!!!!!!! I did have the opportunity to explore a few fossil sites before the fair. My first stop was Bird Hill in Floyd County which is Cerro Gordo, Devonian. Brachiopods abound here. Hopefully, I can get a post of that hunt soon. The second location provided more Devonian finds but from the Solon Member, Cedar Valley Formation. My purpose was to collect some nice spirifers, Platyrachella iowensis. The wings of the spirifers are fragile so the specimens were left in the matrix for the trip home. Last night, while a few spirifers were extracted from a piece of matrix, I encountered two odd things. Oddity #1 The brachiopods were mostly PINK! The spirifers were not. What would cause this???????????? Preservation was obviously poor. Here is a piece of matrix where you can see where the spirifer was attached (The shiny white area). Oddity #2 On the other side of the above pictured matrix, a root beer colored polished object was peeking out. A dremel was used to expose it more. I would say it looks manmade, but knowing it had spirifers next to it, I am without an explanation. It is for this reason that I ask for help. Actually, it reminds me of a piece of Green River Formation that I found containing glass like scales of a gar. Could this also be gar? Any explanations for the unusual find would be appreciated, as this has me stumped and in need of an answer. The final picture shows there is structure in spite of the surface appearing smooth as glass.

Just looking for a group of like minded folks. Then I came by this lovely group when browsing bones on internet, and the rest will be historic! Looking forward to getting some opinions on fossils i have collected.

Hello, I just joined- always been a fossil junkie but just learned about this site. I'm from Iowa and do some hunting here, but the bulk of my hunting is in Wyoming each summer. I'm working on displaying some of my finds from there and will be submitting some items for identification soon. Looking forward to learning with you

A little over a week ago I moved to Louisiana. On the way down I tried to set aside a little time to stop at a few places and collect. I made a couple short stops at roadcuts south of Minneapolis to some success (brachiopods, rugosa, Flexicalymene, etc.) but the most impressive stop was the Fossil and Prairie Park outside of Rockford Iowa. It's surely well known by collectors in Iowa but I found it by accident while researching my route down. A town that owns it's paleontology history is always nice and the town was beautiful. I wish I had more time to hang around and try the bar on Main. Outside Rockford is the Fossil and Prairie Park, the site of an old quarry. The Visitor's Center was unfortunately closed while I was there but there's lots of history and information online. Fossils were absolutely everywhere and it was hard to pry myself away after only an hour there. Easy collecting. The trails looked nice but again I did not have time to check them out. I still haven't had time to go through and identify and catalog everything but I have a general idea on what most are. I felt like if I didn't get around to posting this stuff this week I was never going to. Bad pictures, need to set up a light area here. I also didn't think to pack any of my scale references apparently. A very nice place for sure and occasionally people turn up rarer things such as cephalopods. Still, the diversity is impressive even among the brachiopods.

From the album: Devonian
One of the most complete teeth of this kind I've found so far (intact root, just missing two of the cusps). It's remarkably similar to Orhacanth shark teeth from the Permian, being tri-cuspid with the little "button."-

Yes, sharks used to have spines! Xenacanth sharks in the Permian and Hybodont sharks did as well. This is the only shark spine I've seen from the Devonian - if you've got one, would love to see it.-

I'm new, both to the forum and to fossil collecting in general. As with my new rock hounding hobby, I'd like to keep my collection constrained to specimins I've collected myself as much as I can. Thus far, I have a couple of moderately-sized brachipods (fingernail-sized), several crinoid stem segments, and at least one as-yet unidentified.

I had previously posted this in a Post on a fossil hunting excursion to a Devonian site in Iowa. Since then, the bone has been cleaned up and substantially more bone exposed. I am hoping someone might ID the bone. But probably just a bone chunk! You don't know if you don't ask!!! Mike

Greetings, all! After exploring outcrops and spoils piles from Quebec down to Florida, we are heading west from Delaware to Crawford, Nebraska and back this fall. Planning to stop by Sylvania, OH and Clear Lake, IA. Probably Richmond, IN. Any other suggestions? Thoughts on these three?

Russell Wildlife Area (Oskaloosa, Iowa) Blastoids
minnbuckeye posted a topic in General Fossil Discussion
I visited the Russell Wildlife Area in Oskaloosa, Iowa yesterday. It is a series of old mine pits of Pennsylvanian, Pella rock. Reportedly, blastoids are found here. After spending 4 hours looking, I came up empty, at least in regards to the blastoids. Plenty of other marine finds. I am wondering if anyone has possibly visited the area and stumbled onto any blastoids? Is it a needle in the haystack, or was I looking in the wrong rock structure? Just curious in case a return trip ever occurs. @squalicorax, I noticed you hunted the area. Mike -
I picked up this crinoid filled matrix to put in the children's fossil pit. But as I examined it, I am "imagining" a crinoid crown, albeit, disarticulated. Any thoughts? Am I seeing things? Wishful thinking? Thanks Mike

Hello. There are so many smart members here & I'm just hoping you can put up with someone who didn't listen in science class posting pictures for ID. I've always picked up rocks & what not that look interesting to me & have been content just admiring their beauty. Looking forward to trying to learn at least some basic identification.
