BLT Posted August 12, 2018 Share Posted August 12, 2018 Hello, I am hoping somebody will tell me whether or not this is a fossil. It was embedded in layers of a larger rock (from my yard in middle Tennessee) and appears to be a different color than the surrounding rock. It broke away from the area circled in the last picture.

GeschWhat Posted August 12, 2018 Share Posted August 12, 2018 Unless it sticks to your tongue, I'm guessing a chert nodule. You would have to crack it in half to know for sure.

Rockwood Posted August 12, 2018 Share Posted August 12, 2018 The stain (?) near it makes me wonder if it could be an iron rich carbonate nodule. Link to comment Share on other sites More sharing options...
ynot Posted August 12, 2018 Share Posted August 12, 2018 Just to be clear... most fossils are rock. I agree with the others, some type of mineral nodule. Darwin said: " Man sprang from monkeys."

Auspex Posted August 12, 2018 Share Posted August 12, 2018 Concretions sometimes nucleate around organic material, through the action of bacteria. So, it is possible that it contains a fossil. 3 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

That would make sense, since there are so many chert nodules in other rocks around here. 1 hour ago, Fossildude19 said: +1 for concretion or nodule.

That’s another one I had to google. Maybe so? Thanks! 48 minutes ago, ynot said: Just to be clear... most fossils are rock. I agree with the others, some type of mineral nodule. Gotcha.

I guess I will have to break it to discover whether it does or not. 1 Link to comment Share on other sites More sharing options...
