truceburner Posted April 23, 2012 Share Posted April 23, 2012 This weekend I walked a section of Walnut Creek in Austin (where last I found an ammonite), and came across this colorful little bivalve. Ain't she a beauty? I'm particularly interested in the chevron-shaped bore holes - what causes those? Any info you can provide would be greatly appreciated.

lordpiney Posted April 23, 2012 Share Posted April 23, 2012 they look like worm borings to me. are you sure that shell is Cretaceous in age? looks modern to me. Link to comment Share on other sites More sharing options...
Carl Posted April 23, 2012 Share Posted April 23, 2012 I agree, with Piney - it looks very modern. Link to comment Share on other sites More sharing options...
truceburner Posted April 23, 2012 Author Share Posted April 23, 2012 Thing that went through my head when I found this: Cool Cretaceous bivalve! Thing that did not go through my head when I found this: Any reason to think this is actually Cretaceous? I presumed it was Cretaceous because that's mostly what I find on this creek, but it could certainly be much more recent. Thanks for pointing that out.

erose Posted April 23, 2012 Share Posted April 23, 2012 I think you found someone's lunch. I've got a heap of those next to my compost pile. They were good too! The preservation just seems wrong compared to the local Cretaceous oysters. Link to comment Share on other sites More sharing options...
Tarheel59 Posted April 23, 2012 Share Posted April 23, 2012 (edited) I agree too modern. I live close to the coast of NC and while digging in and around my yard I pull out a handful every now and then. Instead of the garbage they threw them out into holes here, even some in my gravel driveway from 20-30 years ago..There they probally threw in creeks or rivers. Nothing like a couple pounds of smoked oysters or a campfire... Anyone hungry now. Jeff Edited April 23, 2012 by Tarheel59 Link to comment Share on other sites More sharing options...
erose Posted April 23, 2012 Share Posted April 23, 2012 Just need a lemon or two, some tobasco and some fresh horseradish... Always wondered if those big Exogyras were good eatin'. Link to comment Share on other sites More sharing options...

Carl Posted April 24, 2012 Share Posted April 24, 2012 Whenever I find scads of Pycnodonte steinkerns, I picture all the lost oyster meat... Just need a lemon or two, some tobasco and some fresh horseradish... Always wondered if those big Exogyras were good eatin'. Link to comment Share on other sites More sharing options...
