Renee Sterling Posted July 22, 2017 Share Posted July 22, 2017 Both of these were found in Middle Tennessee, not far from Nashville. The area is now a lake, but use to be a river before a dam was built. The first one with the indentations is about 3 inches in length. The one that looks like a bone (but probably isn't?) is about 5.5 inches long and 2.5 inches tall at its tallest point. Any ideas? thanks. Link to comment Share on other sites More sharing options...
abyssunder Posted July 22, 2017 Share Posted July 22, 2017 Welcome to the Forum! The first one is a very interesting find especially by its preservation status. It looks to me the remnant of a crinoid crown (calyx + arms). Just an example of a similar one, in good preservation: pictures from here 5 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

JimB88 Posted July 22, 2017 Share Posted July 22, 2017 I agree with crinoid weathered through for the first. The second seems to be the cast of a burrow or feeding trace (called an ichnofossil.) 2 Link to comment Share on other sites More sharing options...
