ynot Posted November 11, 2015 Share Posted November 11, 2015 It looks like they are in / on a marble. Do not see that they are "crystallized" Tony Darwin said: " Man sprang from monkeys."

Auspex Posted November 11, 2015 Share Posted November 11, 2015 It looks like they are in / on a marble. Do not see that they are "crystallized" Tony Dolomite, maybe?

piranha Posted November 11, 2015 Share Posted November 11, 2015 These are typically found in Silurian exposures across the Midwest. Here are some other examples of trilobites with dolomite crystals: Link to comment Share on other sites More sharing options...
Xiphactinus Posted November 11, 2015 Share Posted November 11, 2015 Those look like the ones found around Grafton, Illinois. Did you find them in Texas? Link to comment Share on other sites More sharing options...
Auspex Posted November 11, 2015 Share Posted November 11, 2015 Those look like the ones found around Grafton, Illinois. Did you find them in Texas? Given that this inquiry is in the "Is It Real?" forum, I think that "found" in this case may not mean collected in situ.

piranha Posted November 11, 2015 Share Posted November 11, 2015 They are certainly not Texas trilobites. Besides Grafton, there are numerous Silurian localities with dolomitic (calymenid) trilobites. Link to comment Share on other sites More sharing options...
fossilized6s Posted November 11, 2015 Share Posted November 11, 2015 I agree, these are dolomite trilobites. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

Twinlukers Posted November 12, 2015 Author Share Posted November 12, 2015 Thank you all for your expertise. I asked this because I've never seen them like this. They are from Wisconsin. Link to comment Share on other sites More sharing options...
ZiggieCie Posted November 12, 2015 Share Posted November 12, 2015 Here is link to my post on Trilobites I found that were replaced with Dolomite. No shell material left, just a perfect cast. http://www.thefossilforum.com/index.php?/topic/57248-a-weekend-trip-you-dream-of;-a-dream-come-true/ Link to comment Share on other sites More sharing options...
