Mila15 0 Posted June 26, 2020 Does anyone know if this could be bone or petrified wood? Share this post Link to post Share on other sites
Harry Pristis 5,603 Posted June 26, 2020 Unlikely to be bone or wood. May be an infilled invertebrate burrow, though. Share this post Link to post Share on other sites
Mila15 0 Posted June 27, 2020 Thank you for your knowledge! I hadn’t even thought about their being fossilized burrows as I’m a novice and just trying to soak up any and all info out their. Also, just came across this forum and, wow, its amazing! Share this post Link to post Share on other sites
Rockwood 3,325 Posted June 27, 2020 The context it was found in could help or contradict the burrow idea. If it seems unlikely that the shape could be easily formed by other means, such as a ledge with fractures roughly this shape and a stream flowing over it, the burrow idea gains credence.

The burrow idea is plausible, but I have seen a lot of limestone weathered out in similar shapes. It looks rather large to my eye for an invertebrate burrow if it is sitting on a 2x4 board. A size reference and location information would go a long way. Share this post Link to post Share on other sites
Mila15 0 Posted July 3, 2020 I found this in southern Indiana in a creek at the bottom of a small waterfall. It is about 14 inches long by about 4 wide and is unusually heavy, which is what led me to ask. Share this post Link to post Share on other sites
