Torie Posted July 17, 2018 Share Posted July 17, 2018 Found this little guy about 2-2.5 inches in Northwest Kansas. I was thinking it was some kind of shell maybe on another shell, or perhaps a layred rock. When I found it, all that could be seen was a tip of the darker brown shell, the rest was completely covered in, I believe, limestone. Anyone know what I’m looking at exactly here? I have another piece much larger that looks very similar, but I am still working on cleaning and preparing it. Once it is finished I will also post pictures of that one. I can add more pictures as well. Link to comment Share on other sites More sharing options...

Monica Posted July 18, 2018 Share Posted July 18, 2018 I think I'm going crazy because this piece looks toothy to me...? 1 Link to comment Share on other sites More sharing options...
Monica Posted July 18, 2018 Share Posted July 18, 2018 Where exactly in Kansas was it found? Here's a link to a geological map of Kansas - perhaps you can pinpoint the age of the specimen that you've found? http://www.kgs.ku.edu/General/geolSheetMap.html PS - Welcome to the forum! 1 Link to comment Share on other sites More sharing options...

The faint lines running up the base of the walls. In trying to make the age fit I came across info. which suggests that rudists can look like barnacles however. They would seem a better temporal fit. 3 Link to comment Share on other sites More sharing options...
BuddingPaleo Posted July 18, 2018 Share Posted July 18, 2018 It would be really helpful to see more angles. I see what you're looking at now. I've got a large barnacle collection, and while they're not from the same areas or times even, they appear to hold pretty steadfast. I took close ups of two approx the same size and have been comparing and contrasting general features of the 'petals', are you thinking the area like along the bottom? This is about 3 inches, it's pretty close looking. Wish my eye was that good! 2 Link to comment Share on other sites More sharing options...

BuddingPaleo Posted July 18, 2018 Share Posted July 18, 2018 The bottom picture is great. It does look barnacley from that angle. If you zoom in on it, kinda looks like smaller broken bases. 2 Link to comment Share on other sites More sharing options...

Cowboy Paleontologist Posted July 18, 2018 Share Posted July 18, 2018 Pseudoperna congesta on inoceramids are a common find in the Niobrara chalk, which has exposure through much of Kansas. My own finds of this sort come from Nebraska, but are still Niobrara chalk. 3 Link to comment Share on other sites More sharing options...

My guess is that it is incrusted with that Niobrara Chalk? I will get a good picture once I have cleaned all that off. There are many little Pseudoperna Congesta, I think. Some have been smashed, some seem to almost be perfect. Link to comment Share on other sites More sharing options...
Ramo Posted July 18, 2018 Share Posted July 18, 2018 99.99% sure it is a piece of inoceramus shell with congesta oysters in Fort Hays limestone. 3 For one species to mourn the death of another is a new thing under the sun. -Aldo Leopold Link to comment Share on other sites More sharing options...

That's probably what's holding it together to a great extent. Those shells are almost pure perforation when it comes to breaking. 2 Link to comment Share on other sites More sharing options...

My experience was finding one solid enough to make it home without needing any prep.. Packaging for the backpack is my specialty. It usually costs me a little extra as a guilt fee in the tip for housekeeping. I tend to be messy and in a hurry. 2 Link to comment Share on other sites More sharing options...

Ramo Posted July 18, 2018 Share Posted July 18, 2018 I'm sure it's fort hays limestone, which technically is niobrara chalk, but not the layer most of us think of when we think of niobrara chalk. Very abanduant in Ellis county ( where fort hays is located), much harder than the chalk out west. If you strike it with a hammer, it rings, where the chalk out west " thuds" 3 For one species to mourn the death of another is a new thing under the sun. -Aldo Leopold Link to comment Share on other sites More sharing options...

That’s very cool. I see it everywhere. It was found in Hays, so it definitely makes sense. Thank you so much Link to comment Share on other sites More sharing options...
