Malone Posted February 13, 2018 Share Posted February 13, 2018 Hi, I found this West of Pueblo not sure what it is. It's approximately 6 inches long. Any ideas? The whole piece is filled with smaller creatures. Any suggestions on cleaning without damaging the small ones? Thank you! Link to comment Share on other sites More sharing options...

JohnBrewer Posted February 13, 2018 Share Posted February 13, 2018 Well it looks interesting whatever it is. Get some pictures up from different angles and put a ruler in at least one image. Got a more accurate location? Maybe show on a map then members can work out the era. That helps a lot as certainly fossils only existed at certain times. Google ‘mass extinctions’ and have a read.

Malone Posted February 13, 2018 Author Share Posted February 13, 2018 This is the back side with a bunch of indistinguishable creatures in it. Is there a way to dissolve the rock and leave the fossils? 3 minutes ago, JohnBrewer said: Well it looks interesting whatever it is.

The berriasian layer. I also saw a video on tv. The iridium layer and all that. I found it West of Pueblo in a debris pile. Probably from the rock canyon anticline.

I think first you need an ID. You need to post pictures of the potential fossil from lots of angle including close ups. And a scale! Don’t use a coin use a ruler. I don’t know the size of anything than British money. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
ynot Posted February 13, 2018 Share Posted February 13, 2018 I think it is a mineral filled crack. Maybe selenite. The overall rock looks like a limestone. (Does it fizz with vinegar?) There are some fragmented fossils in it (maybe whole inside). If the fossils are insoluble in acid, then You can dissolve the limestone to free the fossils. 1 Darwin said: " Man sprang from monkeys."

Malone Posted February 13, 2018 Author Share Posted February 13, 2018 With the addition of the ruler the picture will not load. I tried with several pictures. It seems to add to much information. It measures 6 inches from tip to tail in a straight line. Link to comment Share on other sites More sharing options...

Malone Posted February 13, 2018 Author Share Posted February 13, 2018 Also I don't have any vinegar. Never had a use for it till now. I'll pick some up. Would I just soak the rock in vinegar till it was just fossils left? Link to comment Share on other sites More sharing options...

Would I just soak the rock in vinegar till it was just fossils left? Oh, no, don't do that! You want to be careful with vinegar. As the fossil in limestone will also be composed of calcium carbonate, a far too long soak will dissolve the fossil as well. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
ynot Posted February 13, 2018 Share Posted February 13, 2018 First You need to make sure it is limestone. Do this by taking a small chip off . Crush the chip into powder and add a drop or two of vinegar to see if it fizzes. Then do the same to a piece of a fossil from the rock. If they both fizz then dissolving the limestone with acid will not work to free the fossils. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

JohnBrewer Posted February 13, 2018 Share Posted February 13, 2018 The only time to use lots of vinegar is on proper British fish and chips. With salt of course 2 John Map of UK fossil sites Link to comment Share on other sites More sharing options...

PFOOLEY Posted February 13, 2018 Share Posted February 13, 2018 I would guess...inoceramid inaconcretion. @Malone, I've had some small successes with sledges, hammers and chisels on similar concretions. If there isn't a particular specimen I'm after, smashing it open with a baby sledge can be rewarding. Always wear safety glasses. 1 "I am glad I shall never be young without wild country to be young in.

Ludwigia Posted February 14, 2018 Share Posted February 14, 2018 Continuing along with PFOOLEY's advice, try to remove some of the matrix below the red lines in the first 2 photos and/or give the block a whack with a hammer under the red line in the last one. If there's any shell substance there, then that should at least expose some of it. That would make the identification a lot easier than it is at this point......Sorry. I had to edit this since I noticed that I put the line in the wrong place in the 2nd photo... 2 Greetings from the Lake of Constance.
