hydroweaver Posted February 14, 2015 Share Posted February 14, 2015 Hello ! Thank you for having a site out there for wanderers like us . Can you identify these consecutive grooving patterns ? Are these fossils or just my imagination ? I've posted these pictures online on google+ here : The four "fossils" (Excuse the hair ;-p) And if it helps, I found them here at the banks of Ramganga river in India (Jim Corbett Park), here : Where I found them... It would be amazing to know the truth at least. Quote Link to post Share on other sites
fossilized6s Posted February 14, 2015 Share Posted February 14, 2015 I'm not 100% sure, but these could be feeding traces or tracks (ichnofossil). I'm sorry i can't help more. 1 Quote Link to post Share on other sites
hydroweaver Posted February 14, 2015 Author Share Posted February 14, 2015 at least it's something ! thank you !...waiting for more Quote Link to post Share on other sites
fossilized6s Posted February 14, 2015 Share Posted February 14, 2015 If you search Echinoderm trace fossil there are pictures that look similar. I just worry about the veining in your rocks. Usually metamorphic and igneous rocks will not house fossils. 1 Quote Link to post Share on other sites
hydroweaver Posted February 14, 2015 Author Share Posted February 14, 2015 you're right ! http://sci.waikato.ac.nz/evolution/FossilCenozoic.shtml#Specimen105is strikingly similar ! wow ! Quote Link to post Share on other sites
Sacha Posted February 14, 2015 Share Posted February 14, 2015 I may be way off but it also looks like snails scraping the mildew from the outside of the stones. The stones are metamorphic so intact fossil remains wouldn't be found. Quote Link to post Share on other sites
Auspex Posted February 14, 2015 Share Posted February 14, 2015 I may be way off but it also looks like snails scraping the mildew from the outside of the stones. The stones are metamorphic so intact fossil remains wouldn't be found. My thought exactly Quote Link to post Share on other sites
BobWill Posted February 14, 2015 Share Posted February 14, 2015 Could you give us a measurement across the traces for scale? Does anyone know the geology of the site? Quote Link to post Share on other sites

Cluros Posted February 14, 2015 Share Posted February 14, 2015 I've seen very similar markings on rocks in Boston harbor from marine snails. Quote Link to post Share on other sites
hydroweaver Posted February 15, 2015 Author Share Posted February 15, 2015 so if these are traces, and these are metamorphic rocks, then are these or are these not fossils ? Quote Link to post Share on other sites
hydroweaver Posted February 15, 2015 Author Share Posted February 15, 2015 Could you give us a measurement across the traces for scale? Does anyone know the geology of the site? These were found on giant rocks, I dont have a scale, however, each of these were atleast an index finger in length, if that helps. Quote Link to post Share on other sites
fossilized6s Posted February 15, 2015 Share Posted February 15, 2015 Here's a quick test, I would take a scrub brush to them. If they wipe clean they're obviously not fossils. Quote Link to post Share on other sites
hydroweaver Posted February 15, 2015 Author Share Posted February 15, 2015 they were definitely engraved, these were huge stones on the river bank, you cant wipe them off, thousands of years of river flowing didn't do that ! Quote Link to post Share on other sites
Sacha Posted February 15, 2015 Share Posted February 15, 2015 $10 says a spray of clorox and water makes them disappear. Quote Link to post Share on other sites
BobWill Posted February 15, 2015 Share Posted February 15, 2015 What does Clorox do to a non-fossil? Quote Link to post Share on other sites
squali Posted February 15, 2015 Share Posted February 15, 2015 I think he's referring to the bleach removing algae Quote Link to post Share on other sites
Auspex Posted February 15, 2015 Share Posted February 15, 2015 Gastropods can etch hard rock in the process of feeding; their radula is amazing. Quote Link to post Share on other sites
Rockwood Posted February 15, 2015 Share Posted February 15, 2015 A large excavator is even more effective though. Could this be machine placed rip rap ? Quote Link to post Share on other sites
Auspex Posted February 15, 2015 Share Posted February 15, 2015 A large excavator is even more effective though. Could this be machine placed rip rap ? It is a classic snail feeding track: Quote Link to post Share on other sites
Sacha Posted February 15, 2015 Share Posted February 15, 2015 What does Clorox do to a non-fossil? I am suggesting that this non fossil is mildew, which clorox will remove along with the pattern. I don't believe that the pattern is etched into the structure of a metamorphic rock. It's location near a body of water supports both the snail and the mildew supposition.

Rockwood Posted February 15, 2015 Share Posted February 15, 2015 It is a classic snail feeding track: Maybe so, but it's also the shape left by hardened steel chattering across a rock. Given the title of the post I think context is important. Quote Link to post Share on other sites
hydroweaver Posted February 15, 2015 Author Share Posted February 15, 2015 It is a classic snail feeding track: Can you re-post this picture ? It's not pointing to anything now Quote Link to post Share on other sites

I don't believe that the pattern is etched into the structure of a metamorphic rock. It's location near a body of water supports both the snail and the mildew supposition. dont know much about the snails and all, but here's a look at the river bank where these huge rocks lie, might give you an idea...(all from google, the resort where I stayed...https://www.google.co.in/search?q=ramganga+resort+jim+corbett&es_sm=93&source=lnms&tbm=isch&sa=X&ei=V_XgVMLfNIG_uASl04JA&ved=0CAgQ_AUoAQ&biw=1280&bih=671#imgdii=_&imgrc=BsDa2W9OSB_6SM%253A%3BVPz_hUhTGvf43M%3Bhttp%253A%252F%252Fmedia-cdn.tripadvisor.com%252Fmedia%252Fphoto-s%252F05%252Fa1%252F0a%252F24%252Fcorbett-ramganga-resort.jpg%3Bhttp%253A%252F%252Fwww.tripadvisor.in%252FLocationPhotoDirectLink-g1152784-d303026-i94439972-WelcomHeritage_Corbett_Ramganga_Resort-Jim_Corbett_National_Park_Uttarakh.html%3B550%3B412) Edited February 15, 2015 by hydroweaver Quote Link to post Share on other sites
Auspex Posted February 15, 2015 Share Posted February 15, 2015 Can you re-post this picture ? It's not pointing to anything now It looks fine from here; how 'bout now? 1 Quote Link to post Share on other sites
