Okay, I had originally just thought this specimen was a 'mother nature playing games' kind of rock when I was out exploring on a day that turned out to be filled with lots of trace fossils.
After some online research for Ordovician trace fossils I came across some Flickr photos for Petroxestes pera, bivalve borings, that were once called 'turkey tracks'. The particular photo panel labeled, Petroxestes pera bivalve borings on limestone hardground (Turkey Track Layer, Waynesville Formation, Upper Ordovician; Flat Fork Arm of Caesar Creek Lake, Warren County, Ohio, USA) , looks quite similar to the strange marks I found in this upper Ordovician formation here in southern NM.
Any trace fossil turkey track experts willing to comment?
Thank you in advance, Kato
