garyc Posted December 10, 2020 Share Posted December 10, 2020 Here’s a strange little fragment I found on the Brazos River. I’m not 100% sure it’s bone.... maybe wood. However, it has a different outer texture than I’m used to. Also, the inside appears to have two distinct chambers. I considered antler, but I’ve not seen a broken antler time that has these chambers inside. Link to comment Share on other sites More sharing options...
