austinswamp Posted October 27, 2019 Share Posted October 27, 2019 Good afternoon, I found these here today in Travis county, Texas after a good storm rolled through. I commonly find sea urchin fossils, shark teeth, and oysters from this creek. Thanks Link to comment Share on other sites More sharing options...
grandpa Posted October 27, 2019 Share Posted October 27, 2019 The first photo looks to me like the pyrite deposits typically found in e.g., Shoal Creek. Sometimes they encrust fossils; but this does not appear to be associated with a fossil to me. Now the 2nd photo is really interesting. I'm not sure what that is. It's interesting how it branches at the top and the bottom. Some sort of ichnofossil I'm pretty sure; but what? 1 Link to comment Share on other sites More sharing options...

Randyw Posted October 27, 2019 Share Posted October 27, 2019 When I blow up the second picture it gets fuzzy but they kind of look like crinoid stem pieces to me.... Link to comment Share on other sites More sharing options...
Rockwood Posted October 27, 2019 Share Posted October 27, 2019 The one on the end that is sectioned differently presents a case for a tabulate coral, something like aulopora. Knowing the scale would be helpful. Link to comment Share on other sites More sharing options...
austinswamp Posted October 27, 2019 Author Share Posted October 27, 2019 The second fossil in question is roughly 3 1/2 feet long Link to comment Share on other sites More sharing options...

In this picture they look suspiciously like holes drilled in the rock and filled with loose sediment. Maybe they were drilled in an attempt to split the rock? I could be way off base...

Just getting another train of thought rolling. I agree these appear more like drilled holes (possibly as part of a previous excavation).

Rockwood Posted October 28, 2019 Share Posted October 28, 2019 Wonder how many spare batteries that took. I tried that once but didn't have enough. Link to comment Share on other sites More sharing options...
hndmarshall Posted October 30, 2019 Share Posted October 30, 2019 the pattern looks slightly similar to how something might walk...could they be tracks perhaps?...its a long shot. when a four legged creature walks it leaves a pattern that looks about as laid out as this each mark is not directly in line with the other and it shows a pattern the part where you see them side by side could be where it stood for a moment but then this does not explain the broken off split portion does it?

Mark Kmiecik Posted October 30, 2019 Share Posted October 30, 2019 Tracks of a juvenile T Rex on a pogo stick. That's my line and I'm sticking to it! I've been looking at it for 3 days now and the only thing I've noticed is that the holes seem to be in pairs. Other than that, nada! Possibly just a well-executed prank? Mark.

erose Posted November 9, 2019 Share Posted November 9, 2019 So Travis County is pretty much entirely Cretaceous. But there are many formations spanning a good chunk of the lower to upper Cretaceous. Can you narrow down the location/formation for us? And IMHO those weird holes look man made... Link to comment Share on other sites More sharing options...
austinswamp Posted November 10, 2019 Author Share Posted November 10, 2019 Sure the location is Walnut Creek in austin Texas. Closest to Springdale rd Link to comment Share on other sites More sharing options...

Closest to Springdale rd That would be one if the formations in the Austin Chalk Group, Upper Cretaceous. But I still think we’re looking at man-made holes. The other item does look like one of the typical pyrite nodules. Link to comment Share on other sites More sharing options...
