aggie1997 Posted January 6, 2019 Share Posted January 6, 2019 Hello: My father in law had these specimens in a drawer and we were trying to identify. He worked all over the country so there is not telling about the location. My internet sleuthing says rugose coral? Thanks for any input. Link to comment Share on other sites More sharing options...
Rockwood Posted January 6, 2019 Share Posted January 6, 2019 It's not identifiable as coral. There may be some kind of fossil inside the piece on the left though. It looks like concretion, which sometimes nucleates on fossils . My thought on the other one is perhaps vesicular basalt. 1 Link to comment Share on other sites More sharing options...
Kane Posted January 6, 2019 Share Posted January 6, 2019 I agree with Rockwood's assessment. A rugose coral would be displaying some very key diagnostic features that this piece does not have. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
supertramp Posted January 6, 2019 Share Posted January 6, 2019 I agree with Rockwood and Kane, it looks like some weird concretions with a square hole running down the length of the center we discussed here ciao 1 Link to comment Share on other sites More sharing options...
