surfergirlatx Posted September 24, 2011 Share Posted September 24, 2011 (edited) I found this today at Upper Glen Rose Formation, Trinity Group, Travis County, Texas - Creatous Kgr(l). Its about the size of a quarter. .....Any thoughts? Thanks Kim #1 #2 #3 #4 #5 #6 #7 Edited October 10, 2011 by surfergirlatx "The road to success is always under construction." Author Unknown.

Fossildude19 Posted September 24, 2011 Share Posted September 24, 2011 (edited) There were no trilobites in the Cretaceous. They died out at the end of the Permian. I have no idea what that is, but it's cool looking. Any chance of getting it free of the matrix to see the entire thing? Cool looking, whatever it is!

Indy Posted September 25, 2011 Share Posted September 25, 2011 I'm not familiar with the Cretaceous...However, I think there is enough information here in the pictures to figure out what this mystery shape represents Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Bullsnake Posted September 25, 2011 Share Posted September 25, 2011 In an earlier post of mine on a track, dhk had mentioned isopod. When I searched it, I read that they appeared in the Carboniferous so maybe that's a possibility. Otherwise, is it possible that a trilo fossil was exposed then reburied during the cretaceous?

xonenine Posted September 25, 2011 Share Posted September 25, 2011 i'd say a section of a goniatite is what it looks like, very cool fossil, cant wait to hear what this is...

Cole Posted September 25, 2011 Share Posted September 25, 2011 i'd say a section of a goniatite is what it looks like, very cool fossil, cant wait to hear what this is... Goniatite, trilobite, bivalve or perhaps a gastropod is what I was thinking. Lower right side of pic 2 shows some type of spiraling suture/structure.

BobWill Posted September 25, 2011 Share Posted September 25, 2011 (edited) Oddly compressed Trigonia? That occured to me until I noticed the tubercles you usually see on trigonia seem to be holes on this guy. Right Kim, holes, not bumps, in the rows?

Indy Posted September 25, 2011 Share Posted September 25, 2011 Kim... Trying to focus on just 1 feature of the mystery Ignoring the overall shape of the mystery fossil... Wondering if you have seen (in-line) holes like these on any other collected fossil?

Interesting...Since you have a HUGE collection. Couldn't help but notice the limestone. Apparently collected higher up in the section where fewer fossils exist. Less fossils but often in these zones one finds fossils not found in the lower units.

BobWill Posted September 25, 2011 Share Posted September 25, 2011 If that's an impression of a trigonia it would have holes instead of bumps. For comparison you could look in the limestone blocks that make up the capitol building in Austin. They are full of trigonia external molds.

BobWill Posted September 25, 2011 Share Posted September 25, 2011 the bilobite seems to have 3 body segments, while this fossil has only two segments. umm..."tri"..."bi"...yeah sometimes I get goofy when the science eludes me. Haven't heard from tracer lately. I know, it's a poor substitute. Link to comment Share on other sites More sharing options...
