V1100km Posted March 7, 2022 Share Posted March 7, 2022 Hey y’all. What are these, how old could they be? These were found in the Pflugerville area of Travis County central Texas. 6”/150mm scale next to them for reference. Any insight would be appreciated, TIA!! 1 Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted March 7, 2022 Share Posted March 7, 2022 Yup, fossil oyster shells. Very common find in Texas. You have some really nice specimens there. 1 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

Based on where you found them, roughly 70 to 80 million years old. 3 1 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
BobWill Posted March 7, 2022 Share Posted March 7, 2022 Yes, the species is Exogyra ponderosa s.s. Roemer, 1849. Yours are good examples of the left valve. Watch for right valves, a thinner version, small enough to fit over the concave side. There will be many other mollusks where you find these plus echinoids and maybe even shark teeth. 1 1 Link to comment Share on other sites More sharing options...

Very cool, I’ll keep a look out when I’m in these areas again. I found these by chance just being conscious of my surrounding while at work. Not really a hunter but I may have to start!

Thanks. I thought they were pretty cool so I picked them up. My coworkers thought I was nuts for even paying attention to them(just another rock in there eyes). But to me still a cool conversation piece of history. Link to comment Share on other sites More sharing options...
