Shamalama Posted April 9, 2009 Share Posted April 9, 2009 I have an odd couple of fossils I found in Mississippian rocks in Kentucky a few years back. It comes from the Brooks Hill Road cut in rocks from the Borden Formation. I kept finding these strange dark streaks on the rocks that look like overly large Graptolites or maybe a sponge, but I can't find anything to give me a good ID on what they may be. Any suggestions are welcomed. Thanks! Dave -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Auspex Posted April 9, 2009 Share Posted April 9, 2009 Definitely something... Unfamiliar to me, though.

ashcraft Posted April 10, 2009 Share Posted April 10, 2009 In my opinion, it is a mashed and poorly presreved archimedes. Of course, my opinion and 50 cents will get you a soda in the teachers lounge. Brent Ashcraft ashcraft, brent allen Link to comment Share on other sites More sharing options...

Of course, my opinion and 50 cents will get you a soda in the teachers lounge.Brent Ashcraft I can see the general shape of archimedes, but it seems too large... although it's difficult to tell the actual size from the pics. Was leaning toward calling it a poorly preserved cephalopod, at a guess, since it appears to have chambers... but my opinion will need more than 50 cents added to get the soda. Shamalama, I too have quite a few mysterious items in my collection, and I refer to them as UFO's.

ashcraft Posted April 10, 2009 Share Posted April 10, 2009 I know that most archs you see are small, but they can get quite large. I have a plate with two overlain, one is about 8" long and .75" wide. There is another on the paleolist photo page that is measured in feet (maybe 6 feet? can't remember) Brent Ashcraft ashcraft, brent allen Link to comment Share on other sites More sharing options...

I'm going to have to check that out. thanks for cluing me in!

Amazing! (Brent, I also happened to see a very nice Favosites specimen on that site and was admiring it, when I noticed that you are the one that posted it there!)

ashcraft Posted April 10, 2009 Share Posted April 10, 2009 Yes, I am an equal opportunity annoyer. I annoy anybody, anytime, anywhere. The favosites (if that is what it is) is a student's, who, of course, remembered that I had it and came back and got it. I will try to post a picture of my arch, I have a new lens and have been looking for a reason to break it out.

ashcraft Posted April 11, 2009 Share Posted April 11, 2009 Here is an archimedes of fair size, cut out of the Meramec river bottom, near St. Louis. Warsaw formation, Mississippian. This material is full of silicon spicules and is awful hard to work with. This specimen needs to be gone over with a blaster with HARD grit.

I like that Thanks for posting your specimen, I think it's awesome exactly as it is. After seeing your pic I did some reasearch and found that Arch. is often significantly larger than I'd realized, as you pointed out... would love to see one of the larger-size specimens with the fronds preserved on it!

Shamalama Posted April 13, 2009 Author Share Posted April 13, 2009 Cool pics and links, but I don't think it's an Archimedes as there are no equivalent lacy bits nearby. In fact I don't see any other fossils, hard or soft shelled. The size of the mystery stain in the pics is about 3" long each. I'm leaning toward a sponge or water plant of some kind myself. Thanks for the ideas though! Dave -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Guest solius symbiosus Posted April 13, 2009 Share Posted April 13, 2009 I don't think that it is fossil. To me, it looks like a hard ground is exposed through the over laying matrix. Link to comment Share on other sites More sharing options...
