Today I drove the great distance of 10 whole miles to collect along a creek. I have known about this location for many, many years but did not know the exact location. I first read about it in the old 1964 Edition of "Fossils in America" written by Jay Ellis Ransom. Though i was only 3 years old when this book came out, it must have been a great edition for any fossil collector in the United States. It does it's best to give the location of fossil collecting sites in every state by County. For the fossils that I was after today, Tentaculities oswegoensis, it mentioned that they were found in Kendall County, and this area is the only location that this species is found at. As luck would have it, I received an e-mail from a fossil buddy who mentioned that he had been out there collecting some and he was able to pin point the location for me. It was along a nice creek, but due to the constant rain that we have been receiving, the creek was high and running fast, but I was able to collect a few examples. I do not know if this is a location that I will visit again, maybe when the creek is down, but it was very close to home and I did have fun.

 

These fossils are supposed to be Upper Ordovician in age and from the Maquoketa Group (446-440 MYO)

 

@Peat Burns / @Tidgy's Dad / @Monica you might enjoy this post.

 

Here are some pictures of the creek and the exposure-

Here are some pictures of my finds, first as I picked them up and later with a 1 cm scale cube.

There are also brachiopods to be found there, here are a couple examples.

This rain has been brutal this year. I've had rivers running through it all year. Got to love the clay soil the glaciers dumped in my back yard.

Sweet!! :wub: Thanks for sharing!

And thanks for the locality pics, too. I like this environment very much, these creeks are so similar to some of the larger creeks around me.

And my closest fossil sites are a little less than 10 miles away, both miocene and devonian sites. Well, for the closest devonian sites I have to drive through some traffic-jammed suburbs... 

Thanks again!

Yes that is nice, on Monday I am driving 5 1/2 hours to go collecting and once there, I will have more driving hitting road cuts, it will make for a long couple days.

Thanks for the report and congrats on the finds. Nothing like a bit of detective work to increase the chances of success!

Cool!  Looks like the Tentaculites found in the Larson Quarry near DeKalb.

Very nice, Ralph. 

Those Tentaculites are lovely and the brachiopods rather interesting as well. :)

Thanks Adam and to think that they are only a few miles  from my house- and welcome back.

Awesome finds! I have never seen curved Tentaculites before and those are some big examples too. Thanks for sharing!

I just ordered a used copy of that book for $7 from Abe Books.  I think it's the 1970 edition.

Quite a neat location! I had never heard of this site (nor Tentaculites) but found it after a little detective work. Found quite a few Tentaculites as expected, as well as a few bryozoans and brachiopod fragments (sorry for the lack of scale cube, don't have it with me right now).

You can find Tentaculites at the old Larson now Vulcan quarry in DeKalb.

Nice finds- Looks like the river was running fast.

From what I have been able to gather, the outcrops along this creek are part of the Brainard Formation, which is a member of the Maquoketa Group as suspected.
