Jellyfish Impression? Found On The Nsr

[Kimmersaurus Tex]

About a month ago I found this fossilized "lime" looking thing on the North Sulphur River.

After doing a little research and based on the photo below from Lance Hall's page, I think it is a jellyfish impression or mold.

(about 2/3 of the way down the page)

Of course, I knew it wasn't a lime, but I had nothing to go on for a while! What do you think? Is it or isn't it a jellyfish mold?

Here is the "bottom" (other side) and cross section. I was fascinated with the crystalized holes in the cross section.

It's hard to tell by the pictures, but it may be coprolite.

Lol, that's not Lance's site, it's mine.. I had that posted before I got the correct ID

on here.. I had several ID's in the past (not on here). I tried to correct it on my

site but I can't even find it.. I must have moved it..

In any case here is a pic for you to compare..

The corrected Id is,

"I believe this is a phosphatic fecal bolus from a marine reptile, possibly mosasaur or crocodile. The pattern is created by peristaltic compaction of a fecal mass in the lower part of the large intestine, basically a "grunt ring" created by muscles of the rectum as they both de-water (squeeze the water from) and move the shrinking fecal mass toward the anus. We have similar coprolites (or enterites) from the Cretaceous and Eocene of Mississippi."

I am not sure about yours but I do see why you think that..

I have seen Kimmer's fossil. It looks exactly like the one on Roz's site.

So what you are saying is: it is not the last dying impression of a beautiful translucent creature, its a sphincter-imprinted reptile turd.

Hee-Hee!! *snort*

Haha! I still like it even if it's not a jellyfish mold! Thanks for the clarifications!

Oh yes, it is a cool fossil and I would think an unusual one..

I still want to find a jellyfish though..

My long time curiosity has been solved thanks to the Forum, can now check off a perplexing question that has haunted me for years. I knew this was the after math of a good meal but couldn't understand the strange impressions in the middle, the spincter mystery is now solved----Thanks Roz for the picture---Tom

Now that is cool.. Must be lots of them in that river..

Very good pics too, Tom...

I want to thank George P. for the identification on here

from another post.. It has come full circle.. I love when

that happens..
