Hi all, I found this specimen from a rotary borehole (window sample) at 5.4mbgl within the upper Whitby Mudstone Formation. I’m leaning towards a shell eating fish, but still unsure from the shape of the rest of the the samples which looks more like a coral? The site location is Dundry, Bristol, England. Reported geology: Whitby Mudstone formation Palaeoenvironment: Shallow marine environment Reported age: 174 -183 million years old Any suggestions would be greatly appreciated! Regards Reinier

Hi everyone. I found this extruding from a hillside on Green Mountain near Golden, CO. It is in the Green Mtn Conglomerates formation. Lots of little petrified wood around. Color or is white with some slight red marks. There are small pores but different than what I see with a lot of pet wood. Any help would be great. https://imgur.com/tpVtjNR https://imgur.com/tfv8lO3 https://imgur.com/qFxG2c7 https://imgur.com/FKz5Mr0 https://imgur.com/wwYlheE geology info: https://imgur.com/tiAh2ok
