dhiggi Posted August 28, 2019 Share Posted August 28, 2019 Found this piece on a beach near Whitby known for Jurassic marine fossils. Is it anything of interest; wood perhaps, or just inorganic? Thanks Link to comment Share on other sites More sharing options...
TqB Posted August 28, 2019 Share Posted August 28, 2019 It's a piece of calcite cone-in-cone, a diagenetic sedimentary structure that often occurs in some beds around there. Often mistaken for fossils of some sort - a search for "cone-in-cone" will bring up lots of information. 3 Tarquin Link to comment Share on other sites More sharing options...

Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
