Ordovician Maquoketa Shale SE Minnesota I believe I see a Flexicalymene sp. trilobite and a whole lot more pieces of trilobites. Hence I'm including Caleb's trilo ID rock for reference. I thought if I could get a confirmation or two I would post this hunt as it was a beautiful day in early March to fossil hunt. :-) Well, I guess this will be multiple replies as I don't want to reduce the images where you can't see all the parts. :-)

SE Minnesota - Fillmore County Ordovician Decorah Shale These two fossils, along with many others, were found on a hunt I just hosted. This is a well known and prolific site of Decorah Shale which boosts a lot of trilobites. I believe this is a whole one as to me I believe I can identify a pygidium and cephalon, but the thorax doesn't have the distinctive 3 lobes OR the other two are still buried in the matrix. The plainess reminds me of Isotelus, a small one, but it seems too plain even for an Iso. The other fossil is an obvious imprint but I have never seen anything like it in my collecting here! Thoughts anyone? For scale Trilo top Trilo front with ceph Trilo front super cu, a bit blurred. :-( The "fan". Wet Thanks for taking a lot and any thoughts! :-D

Ordovician Galena Formation SE MN A couple of weeks ago I met with Dave and took him out on a fossil hunt and sold him some maps of various fossil sites. We did well that day, but yesterday he showed up at my door with some fossils he found and some of these are terrific! He definitely has an eye for trilos! :-D And these cephs are huge! I snapped some quick shots as he is having trouble posting. #1 #2 #3 #4 Some great cephs and gastropods! A slice of a big horn coral OR??? Thanks for looking and any IDs you may have on these! :-D Any thoughts on IDs would be appreciated!

On a recent geology bus tour the topic of the cabbage rocks of The Big Woods came up. Geologist Jeff Broberg stated that they were giant stromnipoid reefs left over when the surrounding limestone dissolved away. This is the only known picture of them that I can find: There are supposed to be 5 in the Big Woods on state land. About 20 years ago we were on a horseback ride in that area and they are spectacular in the landscape! As there are a couple of thousand acres in this area of intensely rugged terrain, I am currently attempting to get a local to take me in to photograph them. Ordovician, Fillmore County, MN, Galena Formation, there must be something in the literature about these formations. Does anyone have any information? Thank You! Bev :-)
