JUAN EMMANUEL Posted September 14, 2014 Share Posted September 14, 2014 Is this trace fossil a rusophycus or something else? I also wonder what animal could've made it because I doubt it that any trilobite could have made it. Late Ordovician, Georgian Bay formation, Mimico creek, Toronto, Ontario.

Herb Posted September 14, 2014 Share Posted September 14, 2014 (edited) I don't think so, maybe feeding traces??

JUAN EMMANUEL Posted September 14, 2014 Author Share Posted September 14, 2014 A second take with a different orientation (I almost forgot about this) : Hope this helps. Link to comment Share on other sites More sharing options...
Auspex Posted September 15, 2014 Share Posted September 15, 2014 There is an alternating 'chevron' pattern discernible; the markings are very sharp edged, in contrast to the smooth surface. My speculation is that these marks may have been left by some creature in the water column, foraging in the fine mud surface.

As a bivalve locomotion trail, all the Protovirgularia I can find, look more like these examples: figures from: Buatois, L.A., & Mángano, M.G.

JUAN EMMANUEL Posted September 16, 2014 Author Share Posted September 16, 2014 There's plenty of bivalves from the formation where this came from, so it explains why it could be a protovirgularia. Link to comment Share on other sites More sharing options...

It looks nothing like Protovirgularia. Take a look at the examples posted above. Link to comment Share on other sites More sharing options...
