0lderthandirt Posted August 2, 2017 Share Posted August 2, 2017 Near grand canyon caverns, Arizona. I just found this, looks to me to be a gastropod fossil, or possibly two? Will your next answer to my question be no? Link to comment Share on other sites More sharing options...
ynot Posted August 2, 2017 Share Posted August 2, 2017 Sorry I do not see a fossil in this rock. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Miocene_Mason Posted August 2, 2017 Share Posted August 2, 2017 I agree, it's limestone deceptively worn into the shape of a snail, but there are gastropods to be found there, keep looking! “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
0lderthandirt Posted August 2, 2017 Author Share Posted August 2, 2017 Is it possible to post a short video clip here? Will your next answer to my question be no? Link to comment Share on other sites More sharing options...
Kane Posted August 2, 2017 Share Posted August 2, 2017 Probably would be best to post it on YouTube and then post a link here. With a file size limit of 3.95 MB per post, a video could easily smash that. If you don't wish it to be made too public, there is a setting to make it unsearchable. If you make it entirely private, you won't be able to share the link, however. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Yeah I guess viewing just a flat image doesn't show the perfect raised spiral, or I guess the curved opening and how the smooth side matches. I also don't think I can capture all the tiny creatures embedded around the spiral with my camera anyways. Will your next answer to my question be no?

Arizona Chris Posted August 2, 2017 Share Posted August 2, 2017 That top image looks like the cast of the outside of the gastropods center parts, you are in the Mississippian there I believe and the gastropod that is big like that is called Straparollus. The material look like a brownish chert. ---------------------------------------------------------------------------------------------------------------------------- Arizona Chris Paleo Web Site: http://schursastrophotography.com/fossiladventures.html Link to comment Share on other sites More sharing options...

One is because of a question from @WhodamanHD, I can now stand in the spot that to my north is grey dirt, a few feet deep then solid grey limestone, very few fossils, to my south is soft red dirt that I can easily dig down at least 14 feet and its fossil rich (on surface) The other thing I've learned is there is a context to identifying fossils, giving someone like myself -even though I'm admittedly the least knowledgeable here- an unfair advantage of recognizing... I guess . Like a rock at the bottom of a hill that I can say is a shell only because I've seen the rock at the top of the hill with both weathered and pristine shells still attached, even though I couldn't tell you what the shell is called. Or not Will your next answer to my question be no? Link to comment Share on other sites More sharing options...
Kane Posted August 2, 2017 Share Posted August 2, 2017 We all have to start somewhere! The more you learn, the more you'll want to learn more. You're in an enviable position to have fossils right in your backyard! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
