Rocks n Relics Posted June 18, 2021 Share Posted June 18, 2021 hello everyone, I'm a newbie here and with fossils and hoping y'all's experience can help me out...I live in Globe, Az and I find some awesome rocks and minerals...however I know nothing about fossils...I found this HUGE rock last year and everyone that see's thinks it might be fossils? I do know the area was underwater "back in the day"...so we have lots of limestone conglomerates that formed. The first picture is of a oval shape something that might be a fossil... it's roughly 4" by 2" width. It has lots of texture to it. The parts I'm asking about that might be bone fossils is at it's tallest is 1 1/2 foot tall and roughly 4-5" wide at the top. There are two of the "bones" one in from of the other and they are the same shape and size. The rock itself is roughly 1 1/2 by 1 1/2 feet tall/wide Weighs roughly 150 pounds. Thank you in advance for help! Sheena Globe, Az. Link to comment Share on other sites More sharing options...
Opabinia Blues Posted June 18, 2021 Share Posted June 18, 2021 Nothing you have there looks like a fossil. Someone more well-versed in geology might be able to tell you what sorts of rocks/minerals you have there though. 1 1 “The worse the country, the more tortured it is by water and wind, the more broken and carved, the more it attracts fossil hunters, who depend on the planet to open itself to us.

Fossildude19 Posted June 19, 2021 Share Posted June 19, 2021 Looks like chert nodules in sandstone or limestone. I agree, no fossils. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

jpc Posted June 19, 2021 Share Posted June 19, 2021 The pictures after the cute cat are limestone with chert inclusions. These things can take all sorts of weird and pseudofossily shapes. Excellent example of the stuff. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted June 19, 2021 Share Posted June 19, 2021 (edited) Welcome from Scottsdale. Chert in limestone. The acid rain hits the chert, drips down and selectively dissolves the limestone next to the chert leaving a trough. The formation of the limestone and chert cannot be easily determined without good fossils. Devonian Martin Formation, Mississippian Escabrosa Limestone and the Naco Formation occur in the area. It appears that you might have some green copper mineralization such as malachite on one piece. Most of the richest ores occurred in the limestones. Edited June 19, 2021 by DPS Ammonite 2 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

I live in Globe,az. And my husband works at the copper mine! So it makes since you see possible malachite and such! You guys on here are amazing with your knowledge! Can't thank you enough for a good direction now to start my research! 12 hours ago, Opabinia Blues said: Nothing you have there looks like a fossil.

I honestly have never heard of chert nodules and even after doing Google lens and other resources..no one gave me the correct answer till now! Thank you so much and have a awesome weekend!

Thank you for the information and a funny story about the cat.... he isn't ours, he is a known local stray....I was cleaning up the yard and he wondered onto the property, played down and spread out and took at nap right there lol!
