Michelle Sawicki Library Posted April 20, 2017 Share Posted April 20, 2017 I picked this up today and am wondering if it is a fossil or just an odd shaped rock? Link to comment Share on other sites More sharing options...

EMP Posted April 20, 2017 Share Posted April 20, 2017 Looks crystalline, almost like a geode of some sort. I've heard of crinoid fossils preserved like that, and the last photo shows an intriguing pattern, so maybe it is a fossil. Link to comment Share on other sites More sharing options...
ynot Posted April 20, 2017 Share Posted April 20, 2017 This looks geologic to Me. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Bozark Posted April 20, 2017 Share Posted April 20, 2017 I've found a few pieces of concretion like this in Cretaceous marine sediments, it will usually be gypsum and sulfur deposits between cracks. There is another possibility though. Quite often there are worm burrows around belemnite or baculite shells. Given how worn they are, it could be it's one of those shell fossils with a few burrows just heavily eroded. Do you have the age and location?
