Ramo Posted March 13, 2008 Share Posted March 13, 2008 My wife found this in the Bluehill shale of central Kansas. I have showed it to a lot of people, and nobody can ID it. Any guesses?

Flagponds Pirate Posted March 13, 2008 Share Posted March 13, 2008 It looks like barnacles to me. Link to comment Share on other sites More sharing options...
Ramo Posted March 13, 2008 Author Share Posted March 13, 2008 Sorry about the title of this post, I guess it should have said "unknown cretaceous marine fossil", instead of "What is this".

marnixR Posted March 13, 2008 Share Posted March 13, 2008 it wouldn't be some eroded remains of some colonial coral ? I don't have to know an answer. I don't feel frightened by not knowing things; by being lost in a mysterious universe without any purpose — which is the way it really is, as far as I can tell, possibly. It doesn't frighten me. ~ Richard Feynman Link to comment Share on other sites More sharing options...
MOROPUS Posted March 13, 2008 Share Posted March 13, 2008 I`t resembles to the trace fossil known as Palaeodictyon (Meneghini), Known from the Ordovicic to the Tertiary.The animal that did it is still unknown (possibly a worm). It looks as if the matrix of it has eroded away. I hope this can help you. Link to comment Share on other sites More sharing options...

Xiphactinus Posted March 13, 2008 Share Posted March 13, 2008 My wife found this in the Bluehill shale of central Kansas. I have showed it to a lot of people, and nobody can ID it. Any guesses? I think it's a small, eroded example of a rudist clam, Durania. http://oceansofkansas.com/Invertebrates/durania.jpg Link to comment Share on other sites More sharing options...
Guest N.AL.hunter Posted March 13, 2008 Share Posted March 13, 2008 OK I know this is not correct, but it "looks like" some mud that has fallen of the bottom of my work boots!! Link to comment Share on other sites More sharing options...
Members geofossil Posted March 13, 2008 Members Share Posted March 13, 2008 Looks like a chunk of eroded croc scute... I also think croc Croc..not sure if scute or some of the honeycomed bits of the the skull Link to comment Share on other sites More sharing options...
PrehistoricFlorida Posted March 13, 2008 Share Posted March 13, 2008 While everyone's guessing... I'll guess fish mouth plate. www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...
Members geofossil Posted March 13, 2008 Members Share Posted March 13, 2008 These are scutes. (my collection) They are common finds in our Cretaceous deposits Often the bottoms are eroded and this leaves an open honeycomb effect. Thes second photo (not from my collection) is from the top of a skull. The bone often erodes leaving segments as in bowkills specimen. We frequently find exterior skull bits.

If that's croc scute from Kansas, that is a very, very rare find!!!! Link to comment Share on other sites More sharing options...
Ramo Posted March 13, 2008 Author Share Posted March 13, 2008 X-fish, The edges are 6 sided. I showed it to Mike Everhart, and he didn't know what it was. Where it was found there are lots of what the locals call "Thunderbird eggs" (Serpentine concretions). Here is a side photo that shows that it is crystaline inside. It could be part of a concretion, but I have never seen anything like it before. (I wet it to get the crystals to show up better) 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...

There's papers on the Cretaceous croc Dakotasuchus (spelling?) and others. Link to comment Share on other sites More sharing options...

Maryland Mike Posted April 17, 2008 Share Posted April 17, 2008 I don't claim to be an expert, but that looks suspiciously like a Petoskey Stone (Hexagonaria Percarinata from the Devonian period about 350 million years ago), a fossilized colony coral found most commonly in the Northwestern part of Michigan, but also elsewhere around the Great Lakes. I've seen some very porous stones that looked something like that. Hope this helps. See the attached image. Or possibly Favosites, also colony coral. Here are a couple of links to photos http://www.paleoportal.org/index.php?globa..._section=search http://www.lakeneosho.org/Miss41.html I found mention that Favosites had been found in Johnson County, Kansas.

Guest solius symbiosus Posted April 17, 2008 Share Posted April 17, 2008 It is not one of the Rugose ar Tabulates, they became extinct at the end of the Paleozoic. I'm thinking it is a structural component of lithification. Probably a septarian concretion. They are common in certain beds of the Bluehill. http://www.kgs.ku.edu/Publications/Bulleti...89/09_meso.html Link to comment Share on other sites More sharing options...
