Agkistrodon Posted October 11, 2017 Share Posted October 11, 2017 Found this bone eroding out of a shale layer near a creek in the Lockatong-Formation on Montgomery county Pennsylvania. It measures roughly 10cm long, not sure about this one, any suggestions would be greatly appreciated. Thanks in advance! Link to comment Share on other sites More sharing options...
ynot Posted October 11, 2017 Share Posted October 11, 2017 Looks more plantish to Me. Like Your scale. Link to comment Share on other sites More sharing options...
Plax Posted October 11, 2017 Share Posted October 11, 2017 a good sharp close up shot of the broken end would help. Good to see someone prospecting the Lockatong! Section must have been very weathered. That rock is almost if not actually argillite which is hard as heck. Link to comment Share on other sites More sharing options...
Fruitbat Posted October 11, 2017 Share Posted October 11, 2017 Welcome to The Fossil Forum! I agree with ynot...looks more like plant material than bone material. -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
Agkistrodon Posted October 11, 2017 Author Share Posted October 11, 2017 Thanks very much for the swift responses. I'll try to get clearer images of the broken ends posted later today. Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 11, 2017 Share Posted October 11, 2017 I am in the plant camp as well. My first impression was root cast. But, this view looks like it may have striations down the length of it, which could indicate a cast of something from the Equisetites. group. Can this be cleaned, any further, and pictures taken outside in bright sunlight? Also, pics of both ends and all 4 sides would be good. Prop it up on a flat surface, rather than holding it in hand - this can reduce blur caused by shaking hands. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

Agkistrodon Posted October 11, 2017 Author Share Posted October 11, 2017 Little by little I'm cleaning it but the matrix is very hard so it's taking some time. Thanks for the photo advice, will do. I appreciate all the help, I'm new to the Lockatong -Formation and look forward to a thorough education! Link to comment Share on other sites More sharing options...
Jeffrey P Posted October 11, 2017 Share Posted October 11, 2017 An Equisetites that big that isn't flattened would be a very impressive find. Plant material is very rare in the Lockatong Formation where I collect. Link to comment Share on other sites More sharing options...

ynot Posted October 11, 2017 Share Posted October 11, 2017 Try cropping the picture rather than reducing the file size. Link to comment Share on other sites More sharing options...
Agkistrodon Posted October 11, 2017 Author Share Posted October 11, 2017 Trying to find the fine line between cropping enough but not so much that the picture gets blurry. Link to comment Share on other sites More sharing options...

Plax Posted October 12, 2017 Share Posted October 12, 2017 starting to look like a burrow structure to me now but not a definite ID. Are those crystals in the cross section? have a pic of the outcrop by any chance? 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 12, 2017 Share Posted October 12, 2017 I'm leaning towards burrow or root cast, myself. Just not seeing enough detail on the item to say much else.

Agkistrodon Posted October 13, 2017 Author Share Posted October 13, 2017 No crystals but it does look that way from the photo. This was somewhat of an unexpected find so I didn't have a camera on me. Thank you to everyone for the suggestions, good to have a better idea of what I'm working with here. Link to comment Share on other sites More sharing options...
