val horn Posted May 5, 2022 Share Posted May 5, 2022 went hunting in virginia triassic looking through red stones in construction zones. Didnt find much, the one thing I found looks like a trace fossil to me, though I dont recognize it. I am open to suggestions, the trace is 8c m by one cm of a looking like series of circular flat disks on a thread. Link to comment Share on other sites More sharing options...
cck Posted May 6, 2022 Share Posted May 6, 2022 This looks more like typical weathering of the layers of siltstone in this piece, but there are plenty of trace fossils in those red rocks, so keep poking around. 2 Link to comment Share on other sites More sharing options...

That was my first thought as well. In the process of excavation and moving rocks around a site, plenty of them gouge each other. 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Rockwood Posted May 6, 2022 Share Posted May 6, 2022 Even in other types of construction heavy objects can be dropped or thrown around. Link to comment Share on other sites More sharing options...
val horn Posted May 7, 2022 Author Share Posted May 7, 2022 It was freshly exposed, and i would like it to be something interesting, but that doesnt make it so Link to comment Share on other sites More sharing options...
Rockwood Posted May 7, 2022 Share Posted May 7, 2022 Dewatering feature would be my second thought then. 1 Link to comment Share on other sites More sharing options...
cck Posted May 7, 2022 Share Posted May 7, 2022 Is this conglomerate? Poolesville member or similar from northern VA? 1 Link to comment Share on other sites More sharing options...
val horn Posted May 12, 2022 Author Share Posted May 12, 2022 i dont think it a conglomerate most of the red rock in the area was smooth and without much texture, it is not "potamac Marble" but beyond that I dont know enough geology. ? what is a dewatering feature?

Rockwood Posted May 12, 2022 Share Posted May 12, 2022 The type I've collected occurred when water from pore spaces in sediments was forced through a less permeable layer. Wrinkling is one aspect of it. 1 Link to comment Share on other sites More sharing options...
