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

I was recently sent pictures of something that I am having a hard time identifying online. It was found in a creek bed of Cretaceous age, shallow marine limestone and marl on the west side of San Antonio, TX. It has a section that looks like it was attached to something. It does react to HCL and my initial thought was some sort of coral, but it has a very strange texture. I have seen a number of different types of coral, but never something like this and can't find anything similar. Any ideas? The closeup images of the texture were taken with a USB microscope.
