flyingpenut Posted November 23, 2020 Share Posted November 23, 2020 Here are some pictures of my latest fossil hunting trip. I have been going to post oak creek a lot for shark teeth and wanted to try something new out. I found a steep embankment on a river in Tarrant county with several partial ammonites sticking out. After climbing down the embankment I found an assortment of fossils. I am not sure of the period or the formation in Tarrant county but there was quite a variety. Picture 2 is a conglomeration of marine fossils. Picture 3 is a nice ammonite I went back and chiseled away later. I will post that picture later but it was a very nice enact one. Pictures 4 and 5 are of a nice ammonite that unfortunately broke as I was removing it from the matrix but I was able to piece it back together. It was also interesting to see the internal structure of it as well. The rest are just closeups of common fossils except for the last 4 pictures 13-16 I have no idea what they are. Any ideas? 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 7 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted November 23, 2020 Share Posted November 23, 2020 Nice finds. Gotta love those little echinoids. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

NWARockhound Posted November 24, 2020 Share Posted November 24, 2020 Good stuff! My favorite place to fossil hunt is in Tarrant county by my folks' place. It's just non-stop in the marl. Those are some really great echinoids! Link to comment Share on other sites More sharing options...
Darktooth Posted November 24, 2020 Share Posted November 24, 2020 Looks like you did well! I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted November 24, 2020 Share Posted November 24, 2020 4 looks like a Dipoloceras cristatum ammonite, rather rare. It is a cosmopolitan biostrat marker. Great find. 6 Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...

I have heard you can find one variety at the North Sulphur River but have never had any luck. Then I find all these in about 5 minutes haha. 1 Link to comment Share on other sites More sharing options...

I found all of this in less than 15 minutes where im used to spending all day and finding just a few fossils. Link to comment Share on other sites More sharing options...

GPayton Posted November 25, 2020 Share Posted November 25, 2020 You may already know this, but picture 13 is a partial cross section of a coral - Parasimila sp. if I remember correctly. I've found many specimens that look almost identical in the Comanche Peak formation down here in central Texas. However, after looking at a geologic map of Tarrant County it doesn't seem like there's any of that formation exposed - mostly just Goodland, Woodbine, Kiamchi, etc. so I'm not entirely sure which of those formations you were actually hunting in. Next time you go back to that location you can pull up the Pocket Texas Geology map that the USGS offers on your phone to find out exactly what you're dealing with, but I suspect it's one of those three I already mentioned.

Planko Posted November 25, 2020 Share Posted November 25, 2020 Need to add I am a little jealous of that Dipoloceras cristatum ammonite. What a cool find. Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted November 25, 2020 Share Posted November 25, 2020 I think he’s hunting Goodland, and the echs are Pliotoxaster whitei. 5 Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
