My daughter typically finds sponge fossils and crinoid fossils at our home here in Iowa. However, she found this little guy and brought it in the house to keep. We aren’t sure what it is. I thought maybe it had a lot of iron in it so I used a strong magnet and it didn’t show any ferromagnetic properties. it looks like small bones all bunched together to us. However it is so much different than what we usually find that we thought we would ask for advice. Any thoughts? Could this be a fossil or just some mineral deposit? we look forward to your responses.

Hello, I found this at the beginning of 2018 and haven't given it much thought until I saw the post from 2016 about a strange specimen that looked like Native Americans carved. The topic has been linked below. Below is the specimen I found and was curious if its the same process and is also counter septarian? I also thought they might be beekite rings. Any thoughts and ideas would be greatly appreciated. Best regards, Paul

I tend to track some high end auction sites that deal in (sometimes) complete fossil skeletons. One of these is offering a Dire Wolf Skull. Since it is a for sale site, I do not link to it. However, the seller does provide DETAILED Photo enhancement capability, and the writeup is excellent. So, TFF forum rules, can I cut/paste the photos and the text to this TFF thread for all to evaluate? This would certainly fall into fair use of the materials, even if copyrighted, which I doubt. Dire Wolf. Canis dirus. Pleistocene. Nodaway River, Page County, Iowa, USA I think I have a piece of this but not that big of a piece...

I am down to my last few trilobites to label from this summer yet. Am open to suggestions on these less than perfect finds: 1. Found in the Galena/ Ordovician of Iowa. Isotelus? If so, is the species obvious? 2. Found in the Platteville formation/ Ordovician of SW Wisconsin. Flexi? 3. Another Galena/ Ordovician but from Minnesota

I have a little rock, smaller than a marble. It looks like a fingerprint on a rock. Any ideas what it is? That's a marble for size comparison.

I have some fossil elk vertebrae and I would like to display them upright. Any suggestions for stands that can hold these in a stable way? Thanks

I can't seem to find an ID for this find. I believe this may be a siphuncle. What do you guys think? The "V" shaped sutures are really throwing me off. Has anyone seen a straight shelled cephalopod with this "V" pattern? Kinda neat how you can see how this was buried, preserving one side as it weathered the other. Then along came a dozen crinoids or so a used it as a nice base.

Finally got around to posting here after lurking for a few months. I have a science background and have always been casually interested in evolutionary biology. But having to keep ahead of 3 kids obsessed with prehistory has forced me to up my game and sparked my own interest. At this point, I’ve just been purchasing specimens but hope to start collecting for myself soon. Many thanks for the wealth of knowledge and wonderful community that this board provides!

Last Autumn, I found a large favosite coral embedded in quite a bit of matrix. It measured 24cm by 13 cm, which is large for the location it was found in. It was only a coral, but I put quite a few hours into prepping this piece. Finally done!!!!

Hello! I found this mandible yesterday in a creek in Linn County, IA. It reminds me of a modern whitetail deer, but I'm not sure. One thing that stands out to me is that the middle tooth has three labial lobes. I have a modern whitetail doe adult to compare it too (see last picture), but only the end tooth has three labial lobes. Does that mean this isn't a whitetail deer or is that normal genetic variation? Total length of mandible (broken): 83 mm Thickness of mandible: 19 mm Width of tallest tooth: 20 mm Thickness of tallest tooth: 9.4 mm Thanks! @Harry Pristis

In an old collection I found this small tibia. It is missing the proximal end. I believe this fossil came from Lower Snake Creek making it Miocene. I have no idea what this would have been from. Ruler in pictures is in inches.

Mike @minnbuckeye kindly sent me a package of orthocone nautiloids from his area recently. It's one of the taxa that are sparse in my collection so I was happy to accept the offer. I'm posting them to show what a generous guy he is and to elicit more info about them that might be missing... I don't think that big one in the lower right was labeled - Is it the same as the other large one, Elgin IA?

Hey all, I found this slab of rock in a Linn County, IA creek this spring and I'm not sure how these patterns might have formed. Are they trace fossils from something? Did they form for normal geological processes? It's hard to pin down age of rocks in a creek like this, but most of our exposures are Devonian or Silurian. Thanks!

Went out to Iowa for a Devonian hunt. Found a few placoderm teeth and what I'm told is a Dunkleosteus jaw/tooth bit. I'm happy. Can't wait to go back this Fall. I also found some nice crystals, pyrite and partial trilobites. Placoderm material Anyone know what this is from? My best guess is possible shark tooth.....? Dunkleosteus bit (it needs some prep and reconstruction)

Hello, I'm a new member to the Fossil Forum, could someone please help me ID these teeth? I found the larger, blacker tooth this morning on a sandbar of a creek in Linn County, Iowa. My wife found the smaller tooth on the same little sandbar about a year ago. I have found several bison teeth in the many other locations I have walked up and down this river, but these two have been stumping me. These are the only teeth we have found so far that still have roots intact which leads me to believe that they did not travel very far in the creek. These may or may not be from the same animal, but two strange teeth from the same spot makes me wonder if that could be the case. The smaller one has a stylid, but even the small one is thicker than the bison teeth that I have. Two photos compare size to a modern bison jaw. Small tooth: Width: 26mm Thickness at top: 16mm Enamel height: 32mm Large tooth: Width:29mm Thickness at top: 27mm Enamel height: 14mm

I collect in Coralville Iowa frequently and always run across these brachiopods. Yet I am unsure of their name in spite of investigation on line. They are NOT uncommon so the ID should be easy but eludes me. So here I am asking for assistance! They are flat as a pancake if that helps.

So Thursday afternoon i drove 3 1/2 to the Clarion Hotel in Iowa City, Iowa so I could be up bright and early for the start of the show. Like Tucson and other show locations, there is a Hotel Show that takes place inside the Clarion on Thursday thru Saturday nights. I have to admit that I had more fun at the Hotel Show versus the couple hours that I spent at the actual show today. I would guess that there were maybe 30 rooms that were open and that contained mostly fossils, but some minerals. Not all of the vendors at the hotel participate in the actual show. With that said, I was really disappointed in the amount of vendors that showed up today for the show, but I did hear that there was some show taking place on the East Coast, and many of the vendors went there. I will start with a few pictures from the Hotel Show. Here are Pics from the actual Show:

Two weeks ago while I was at the ESCONI Fossil / Mineral Show, I bid on and won a great little piece of rock that was identified as Isorthoceras sociale Cephalopods from the Upper Ordovician - Maquoketa Formation of Graf, Iowa. I did a little research before heading out to the MAPS Show yesterday and decided on my way back home, I would take a 1 1/2 hour detour to Graf and see if I could find this small road cut. I have to admit that this approximately 300 ft long road cut contains what must be some type of mass Nautiloid death bed. There are so many of them that you will for sure go home with your fair share if you ever get a chance to visit the very out of the way place that is hidden among farmland. I will give a couple warnings for this location- there is no shoulder to park on and you have to drive on the grass/dirt area that is muddy. Secondly, people have under cut these Nautiloid beds and there are TONS of rocks above your head in sections of this road cut; It is not a place for young kids nor a place for a Risk Taker. Besides the Isorthoceras sociale that I found, I also found a couple nice Gastropods. This is a place that I will not visit again since I did collect enough loose pieces and blocks that I found around the area. Here are some pics of the area as well as some of my finds:

Mystery here. I found this near home on the banks of the Mississippi River here in east central Iowa. The geology in this area ranges from Ordovician to Pennsylvanian but with lots of glacial erratics and glacial mixing, not to mention the river mixing everything up!! It looks like a fossil concretion kinda like the Mazon Creek ones but is unusually polished, like a celt. Any input would be much appreciated!

I found this tooth in a dry creek bed in NE Iowa. The area I found it in is unique due to the fact that even though it is surrounded by farmland, the sheer rock bluffs and rock overhangs cut by the little creek over the centuries made this area unsuitable for farming. Northeast Iowa was apparently missed by many of the ice advances during the Ice Age so the area as a whole has a much older surface geology than found anywhere else in the state. The tooth is between 1 1/16” and 1 3/16” in all measurements. It looks too old to be from a cow though I’m sure they have been in the area since first settled. The closest thing I’ve found myself online is a tooth from a prehistoric camel. Any help IDing it would be much appreciated!
