DVL Posted August 9, 2021 Share Posted August 9, 2021 Hi All- This was found in a creek bed in Northern NJ (not Big Brook). 3 1/4 inches long. Bedrock is early Jurassic but a mastodon or mammoth tusk was found a few miles away (I assume Pleistocene material could be found just about anywhere?). It resembles some teeth I've found online (mastodon and gomphothere). Interesting crystal structure. Thank you- Dwight Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 9, 2021 Share Posted August 9, 2021 Not a tooth - no enamel present. This looks like quartz or calcite. 1 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Tidgy's Dad Posted August 9, 2021 Share Posted August 9, 2021 Quartz / calcite and a bit of banded agate / chalcedony by the looks of it. 1 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
DVL Posted August 9, 2021 Author Share Posted August 9, 2021 Thank you both! I'll keep looking; I've yet to find anything from the Pleistocene. Link to comment Share on other sites More sharing options...
val horn Posted August 9, 2021 Share Posted August 9, 2021 The crystal on the surface certainly looks geologic. And it does not look like a tooth. but what is internal area with that spongy and tubular structure . It looks more patterned than simple iron stone Is it coral? Or even my most favored wood tempskya? 1 Link to comment Share on other sites More sharing options...
DVL Posted August 9, 2021 Author Share Posted August 9, 2021 Thank you Val- that spongy texture threw me off too. Coral might be a possibility; I've found coral in the area before (deposited by glacier), but it was in a slab of limestone and doesn't look anything like this specimen. I don't believe any petrified wood has been found there. Quick question for you or anyone else: is the crystal/quartz replacement not possible in a Pleistocene fossil? I'm obviously not an expert.

val horn Posted August 9, 2021 Share Posted August 9, 2021 i have never seen it, but that says more about my limits than anything else. 1 Link to comment Share on other sites More sharing options...
