My family and I found this on the shoreline of Whitmore Lake, Michigan. I am certain it is a “tailbone“. You can see the spinal canal very clearly as well as the classic 3 segments in the coccyx bone. Looking for help identifying and how to connect with a team that could evaluate and possibly carbon date?
Hi Amber, this does have an odd shape, but it is not a fossil. It’s likely either sandstone or ironstone that has been weathered into this peculiar shape by water flowing through it. Bone has a very distinctive porosity, which this lacks. I hope this helps!
<span class=”atwho-inserted” contenteditable=”false” data-atwho-at-query=”@victor”>@vperez</span> thank you for your review. I doubt this last image would change your mind, but I thought I’d attach anyway. I do understand the porosity you mentioned. Do these image change your eval? Just want to make certain before we move on from this find.
One last thing. It is possible the item was brought to the lake from a dig site. We purchased tons of rock from a dig site/Quarry to place on the shoreline behind the house. So we don’t know for sure that it came from the lake as we found it in the rocks that were purchased a few years ago.
