Innocentx Posted January 19, 2019 Share Posted January 19, 2019 Interesting find! The part that sort of looks like a tooth or arrowhead, appears to be limestone (you would need to run some tests to make sure). The rest are crystal growth (my guess, calcite). Funny how rocky things can end up looking so much like something else. 2 "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
Rockwood Posted January 19, 2019 Share Posted January 19, 2019 The shape is common when small chunks of a layer (or crack fill) of harder mineral breaks off with some of the softer surrounding rock and is subjected to wear. 3 Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 20, 2019 Share Posted January 20, 2019 I agree with Dale's assessment. This look geological in origin, rather than biological. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
