oh_joy50 Posted August 11, 2019 Share Posted August 11, 2019 Hello. My name is Joy and I know I will find this forum very useful. I am learning about how to spot fossils and may need help from time to time. I found this today here in Katy in a pile of rocks near a flower bed and would really like your input on what I am looking at. Thank you for your time and expertise.

caldigger Posted August 11, 2019 Share Posted August 11, 2019 Joy, would you mind taking a shot of it straight on and not at an oblique angle? I am getting a Karst ( cave formation ) feeling on this. Link to comment Share on other sites More sharing options...
grandpa Posted August 11, 2019 Share Posted August 11, 2019 Hello Joy and welcome to TFF from Austin, Tx. Other pictures may prove me incorrect, but from what I can tell, I believe what you have is a piece of banded chert showing an erosion pattern which results from the bands being different in hardness and thus some eroding faster than others. BTW, you've come to the right place to ask such questions and again, Welcome! 2 Link to comment Share on other sites More sharing options...

grandpa Posted August 11, 2019 Share Posted August 11, 2019 Thanks for the additional photo. I'm still of a mind that we're dealing with a piece of chert. 2 Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted August 11, 2019 Share Posted August 11, 2019 I would like to see the sides, all four, and the bottom. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

grandpa Posted August 11, 2019 Share Posted August 11, 2019 Still liking my odds. Those half-moon shaped divots along the right edge of the specimen in the 1st photo of your latest round of photos say conchoidal cleavage to me - again a feature of chert. 1 Link to comment Share on other sites More sharing options...
FossilNerd Posted August 11, 2019 Share Posted August 11, 2019 Unfortunately, I don’t think you have a fossil. I’m not up enough on my geology to say for sure what it is (although I do like grandpa’s assessment of banded chert) but it’s a cool geological piece to be sure. Just not a fossil. Oh... and...

FossilizedJello Posted August 11, 2019 Share Posted August 11, 2019 Hey, i am not exactly sure what type of rock but I have seen it before. As others said maybe chert, maybe a sandstone of sorts. Link to comment Share on other sites More sharing options...
