Jandm27 Posted August 14, 2018 Share Posted August 14, 2018 Found these in the tall pine forests of Northern Arizona, at about 7k ft elevation. Saw the edge of one sticking out if the dirt after a big storm, and it was unlike any other rocks in the area. The second was found within inches of the first. I dont even know if they are actually fossils, but they dont look like petrified wood, and they certainly aren't rock, feel more like glass or porcelain.

JohnJ Posted August 14, 2018 Share Posted August 14, 2018 They look like chert nodules and can be highly variable in shape or color. 3 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 14, 2018 Share Posted August 14, 2018 These look like chert nodules. Sometimes, nodules/concretions can contain fossils, but I am not seeing any fossils on the outside of these. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

ynot Posted August 14, 2018 Share Posted August 14, 2018 Looks like a chert nodule that has been exposed for a long time. 1 Darwin said: " Man sprang from monkeys."

FranzBernhard Posted August 14, 2018 Share Posted August 14, 2018 Sure these look like chert nodules! But I have two questions: 1. Is the location/formation right for chert nodules? 2. In the large photo, there seems to be a stylolite running from lower left to upper right, probably cut at a very oblique angle. But this interpretation can also be total bogus and this feature only a random crack. Franz Bernhard Link to comment Share on other sites More sharing options...
PaleoRon Posted August 14, 2018 Share Posted August 14, 2018 They appear to be chert nodules. Where there is chert there are often fossils. Link to comment Share on other sites More sharing options...
abyssunder Posted August 14, 2018 Share Posted August 14, 2018 I agree that is chert. Try to compare with tripolitic chert.

DPS Ammonite Posted August 14, 2018 Share Posted August 14, 2018 Welcome to the Forum. It looks like chert to me, similar to that from the Permian Kaibab Limestone. Look at my geological maps section of my Arizona Paleontology Guide to find out what rocks are in your area. link What formation is it from? My goal is to leave no stone or fossil unturned.

Jandm27 Posted August 14, 2018 Author Share Posted August 14, 2018 Thank you all for the quick responses! And we hoped we have found the fossils of indominus rex! Still some cool rock formations, I guess the kids can play with them now. Link to comment Share on other sites More sharing options...

Looking at the maps you linked it would either be Basalt or Kaibab Limestone. Where we were at is right on the border of an area that has both.

Any other color and it was most likely the limestone. Both can have cryptocrystalline quartz in them. Darwin said: " Man sprang from monkeys."
