Jrh38654 Posted August 8, 2017 Share Posted August 8, 2017 I found the following samples today in northeastern Mississippi at the Cretaceous park site. I'm curious what the little fossilized designs in item 1 are. And I'm thinking item 3 may be a tooth of sorts? I also found this tooth and was wondering if it was a modern deer tooth, or fossilized something? Does anyone have any advice on how to tell?

Miocene_Mason Posted August 8, 2017 Share Posted August 8, 2017 1 looks like bryozoans. One way to tell if something is fossil or not (at least with bone) is the burn test, but this is destructive. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
ynot Posted August 8, 2017 Share Posted August 8, 2017 1 bryozoan. 2 need more pictures. 3 need more pictures. 4 bovid tooth. The "burn" test- hold a flame to a suspect bone and if it is recent it will smell like burning hair. Darwin said: " Man sprang from monkeys."

Al Dente Posted August 8, 2017 Share Posted August 8, 2017 Number 3 is the root end of a sawfish rostral tooth, most likely Ischyrhiza mira. Link to comment Share on other sites More sharing options...

abyssunder Posted August 8, 2017 Share Posted August 8, 2017 I just see the topic, and I agree with the others. For 2, here are comparative specimens. comparative pictures from here and here Specimen 4 looks to be deer cheek tooth. I would use Harry's gallery picture for comparative reason.

TNCollector Posted August 9, 2017 Share Posted August 9, 2017 3 is base of Ischyriza mira mira rostral denticle. 4 is a modern, unfossilized deer tooth. Link to comment Share on other sites More sharing options...
Wrangellian Posted August 9, 2017 Share Posted August 9, 2017 The bryo piece looks so Paleozoic.. are you sure it's Cretaceous? Link to comment Share on other sites More sharing options...

I'm not sure, I'm just basing it off what the site is known for. It is a creek in northeastern MS that is full of shark teeth from the Cretaceous.

TNCollector Posted August 10, 2017 Share Posted August 10, 2017 The site is in the Cretaceous Demopolis formation. I have found Paleozoic stuff in the concrete/gravel they use to fill the parking lot. Link to comment Share on other sites More sharing options...

Dunnicrinus Posted August 17, 2017 Share Posted August 17, 2017 PLAX hit the nail on the head. There is a rip-rap revetment along the creek you are collecting near Baldwyn, Miss. (and, regrettably, along many streams in MS and elsewhere). The rip-rap is composed of limestone boulders derived largely from limestones of Mississippian age (Paleozoic Era) in NW Alabama, largely the Tuscumbia Fm (or so I am led to understand). That hard, crystalline limestone, which, again, is not native to that specific area, can be abundant with fenestrate bryozoans, including Archimedes. Your rock above looks as though it may have captured a tangential section of an Archimedes colony. Link to comment Share on other sites More sharing options...

We see this type of erosion control here around the Dallas/Ft. Worth area and find things totally out of context with the surrounding deposits.
