From the album: Durant Pond Site trip November 11, 2023
This site is exposed in the footprint of a shallow pond. The underlying limestone appears to have been exposed in the process of building the pond. The mud in between the exposed limestone is rich in clay and incredibly sticky. -

I have identified the rock as Limestone from the CSX Wauhatchie Yard in Chattanooga, Tennessee. There appears to be some sort of pattern or striations on the outside of the rock. My rock community has deemed it as a fossil of some sort!

Horseshoe Crab with Modest Color Enhancement
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
This piece is supposedly a horseshoe crab ( Mesolimulus walchii) from the Solnhofen limestone of Germany. It is Jurassic and the description says there has only been mild color enhancement. Is this fossil real? Any fabrication? Thanks for the answers!

Hello, I found this rock in an ephemeral stream bed with what I think is an ammonite and crinoid head in the same rock. I'm somewhat familiar with the local geology and fossils but not 100% sure. It was found in Columbia MO in what should be part of the Osagean series of the Mississippian. Most common rocks in the area are limestone, chert, and dolostone; crinoids are extremely common. I'm a lot less confident on what I think is a mold of a crinoid head (second fossil pictured). I just hope it's not a chert nodule. Anyways I would love to hear other opinions to confirm this. Thanks!!!!

Two fossils from Miocene limestone on Yapen Island, New Guinea, Indonesia
David Cothran posted a topic in Fossil ID
Hello, I collected these two fossils on Japen Island, in Cenderwasih Bay on the north coast of West Papua, New Guinea. The site is Miocene carbonate rocks, just above sea level. First and second images are two sides of specimen 1, with a one Euro coin for scale. Third image is a close up of the side shown in image two. Fourth image is specimen 2, again with the one Euro coin and the fifth image is a close up of that. Specimen 1 looks like Syringopora coral to me. Really no good idea about specimen 2; bryozoa? Any help with ID is very much appreciated. Thanks!
