Mississippi Cretaceous period

Recommended Posts

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?

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.

Happy hunting,

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.

Will Rogers said: " Some of them didn't spring far enough."

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.

2 looks like a gastropod operculum

3 is base of Ischyriza mira mira rostral denticle.

 

4 is a modern, unfossilized deer tooth.

The bryo piece looks so Paleozoic.. are you sure it's Cretaceous?

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.

could be a paleozoic river transported erratic but if the rocks right we do have bryozoa in the eastern cretaceous.

The site is in the Cretaceous Demopolis formation. I have found Paleozoic stuff in the concrete/gravel they use to fill the parking lot.

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.

Excellent explanation, welcome to the site and hope to see you here often.

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.
