0lderthandirt Posted December 25, 2019 Share Posted December 25, 2019 The last few pics have rhizoliths and the round buttons in the last one are crinoids Will your next answer to my question be no? Link to comment Share on other sites More sharing options...
Scylla Posted December 25, 2019 Share Posted December 25, 2019 I used to collect these near Tucson, AZ. There are all sorts of fossil and geological oddities in these rocks. I have some with very clear rugose corals (horn corals) in red on a grey background. The red is silified material and the grey is a limestone/marble so the grey weathers away over time leaving the quartz behind. 2 Link to comment Share on other sites More sharing options...
