Hello, Roommates! I received this little trilobite as part of my Secret Santa package, and, though i know the eyes are missing, and parts of the pygidium etc., am rather fond of the little fellow. The label with it said Illaenus americanus and it was said to be from the Galena Limestone, Upper Ordovician nr, Postville, North East Iowa, a quarry or a roadcutting. Now the first thing I discovered, and please correct me if I'm wrong, is that the name is no longer valid and this is now Thaleops laurentiana. And on looking closer, it doesn't seem to be it at all. The lack of axial furrows and general effacement led to me to think Bumastoides sp. so i then read up on the paper https://www.researchgate.net/publication/257656692_A_systematic_revision_of_the_Upper_Ordovician_trilobite_genus_Bumastoides_Illaenidae_with_new_species_from_Oklahoma_Virginia_and_Missouri?enrichId=rgreq-42948ac4406fefc77dead768950eae0b-XXX&enrichSource=Y292ZXJQYWdlOzI1NzY1NjY5MjtBUzo5NzE0MzExMzEyNTg5NUAxNDAwMTcyMTMxNjE4&el=1_x_2&_esc=publicationCoverPdf and so on. I also discovered this (second item down, left hand margin : http://www.robertcharleswolf.net/newsletter942186.htm So it could actually be Maquoketa Formation, Elgin Member. The specimen seems to have 10 segments in the thorax so I'm thinking B. porrectus or B. beckeri. Any help greatly appreciated, here are a few photos:

Thanks to @minnbuckeye who gave me a site suggestion to an Iowa Devonian locality when I was on my way to the White River Formation of Nebraska, I was able to satisfy my palaeozoic fix this past June. Here are my finds (scale in photos is cm/mm): Orthospirifer cf. O. cooperi Strophodonta sp. Cranaena sp.

As much as I've looked through books and the internet, I haven't run across any possible places to find ammonites in the midwest. Any suggestions of locations? I'm in Illinois. My wife's keen to hunt one of these down.

Last Sunday I had the opportunity to travel to East Central Iowa to collect Devonian fossils. It was a nice foggy morning drive to the quarry. Upon approaching the quarry, there was a house burning down- a odd, surreal scene. At the bottom of the quarry could smell the smoke from the house. No pics of the quarry were permitted which is too bad as it is a geologically fascinating place. Devonian Cedar Valley formation, lower Solon exposed as well as Pennsylvanian karsts. Here are a few of my finds. Hexagonaria Trilobites. Eldredgeops peeking out from the rocks Acleistoceras sp And last, but not least, this nice crystal. Thanks for looking. Cheers

Found this fossil at Rockford, Iowa, last week with a student group, and it didn't show up on our identification sheets. It's about the size of a quarter. Can anyone tell us what it is? Thank you.

Again, this was a surprise found in the Burlington Limestone while looking for the ever present crinoid. It is hollow and of a color that I had never seen. Any thoughts are welcomed. Mike

This was discovered while hunting in the Burlington Limestone in no other than Burlington, Ia. If anyone has hunted this formation, they would know 90% of the rock is made up of light colored crinoidal debris. Occasionally a brachiopod s encountered and they may be darker than the crinoids, but pale against this. I know there is a fish layer in the Burlington and am hoping that this may be the ID.

I apologize that I didn't take a better picture. I realize that you don't have much to work with but I'm wondering if anyone can help me ID the largest fossil that's visible in this rock. I didn't put anything in for scale. The rock is sitting on a paper towel (not the best reference for size). I believe it is surrounded by straight cephalopods. I was with my cousin when she found this fossil on her private property in Epworth, Iowa. I'd like to know more about this fossil. I am a science teacher and I'd like to share this picture with my class and I'd like to know more about it to answer any questions that may arise. The actual fossil is still in Iowa at my cousin's house. I may be able to have her take additional pics.

Cephalopods and a few Questions for thee experts.
fossilized6s posted a topic in Fossil Hunting Trips
I drove about 4hrs west to find trilobites, came home with cephs. I did happen to find some pretty neat trilobites, but they need prepping, so i won't post them. Hunting more for trilobites this year i come across a lot of other fossils and i find it exceedingly hard to leave a neat looking cephalopod behind, so i grab em. Most of these will be left outside, but some are nice enough for display. Here are some nice ones. I love the contrast and size on this piece. The isotelus cephalon and worm burrows don't hurt either. Continued....- 15 replies

Hello all, I am looking for good reference material to identify fossils I picked up at Rockford, IA. I haven't been able to find a really good publication that covers the majority of what is find-able in Iowa's Devonian deposits and I'm hoping you can point me in the right direction. Thanks!

Hello, I am new to fossil hunting and was wondering if I could get any pointers on localities in my area. NW Iowa, NE Nebraska, SE South Dakota, SW Minnesota. I know sometimes people like to keep these things secret but if you could point me in any direction it would be much appreciated, thanks and happy to be on the forum.

Found this piece in Iowa yesterday while hunting trilobites. I've never seen anything like it. The six point symmetry with it's bulbous tips are very strange. And the fact that it is very water-worn doesn't help with an ID. I'm thinking holdfast or possibe starfish. What do you guys see? Scale in mm/cm

A recent trip to Coralville, Iowa provided me with these coral specimens, each unique in their own way: 1. I posted this a few weeks ago prior to removing most of the matrix from it This rugosa coral was huge!! Check out the scale. 2. The next coral might be mistaken for a mushroom: Oops, I meant this one:
