Montana8 Posted November 30, 2019 Share Posted November 30, 2019 I found this short-stemmed mushroom-looking thing on my favorite fossil beach in New Zealand. Any identification pointers would be much appreciated. It is very hard. The stem looks and feels agatized (or something like that) to me. I can't tell if the cap is really petrified or just really hard. A couple weeks later I found a similar mushroom-shaped thing on the same beach -- the caps are super similar, but the second one has a very long stem. I"m posting pictures of the long-stemmed one in a separate thread. Thanks for any thoughts. Link to comment Share on other sites More sharing options...
Rockwood Posted November 30, 2019 Share Posted November 30, 2019 It's an interesting shape. I can't see any features that are not consistent with it's being a fragment of a concretion though. Link to comment Share on other sites More sharing options...
