Hoosier Hound Posted September 3, 2019 Share Posted September 3, 2019 Hi, I found this concretion near a Bloomington construction site associated with a pile of limestone rip-rap. It was already broken and I didn't find any other pieces in the area. It looks like it might contain a fossil. What do others think and how should I proceed with it?

grandpa Posted September 3, 2019 Share Posted September 3, 2019 I believe this is a chert infill in a limestone pocket. I think it is a geological occurrence, not a fossil. Good eye to notice that this stands out from the usual material in the rip-rap. Next time that good eye will lead you to a fossil. Link to comment Share on other sites More sharing options...
Hoosier Hound Posted September 3, 2019 Author Share Posted September 3, 2019 Thanks! Of course I will keep looking. It reminded me of some of those Mason Creek, Ill. concretions with fossils. Link to comment Share on other sites More sharing options...
Plax Posted September 3, 2019 Share Posted September 3, 2019 Maybe one of out trilobite experts will have a look at this. Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 3, 2019 Share Posted September 3, 2019 What is the size of the item? Not really seeing anything fossil-ish in this, however.

Hoosier Hound Posted September 3, 2019 Author Share Posted September 3, 2019 sorry, the size is about 3 and 3/4 inches long, and 3 inches by 2 and a half inches for the oval cross section. Link to comment Share on other sites More sharing options...
Hoosier Hound Posted September 3, 2019 Author Share Posted September 3, 2019 Oh that's Mazon Creek, Ill., not Mason, I mean. Link to comment Share on other sites More sharing options...
