Jim, they look similar to a type of Thalassinoides burrow system referred to as Quebecichnus. I have seen similar things, minus the strong, apparent oxidized pyrite rim.

Subject: Paleonet: possible Silurian trace fossils




Attached are some pictures from the Mississinewa Shale (Silurian) near Wabash, Indiana, USA. I would guess these to be fossils, either traces or perhaps some kind of macrophyte algae.



(I know a bit about trace fossils, but mainly those made by big land animals with backbones and nasty teeth.)



Can anybody give me a better suggestion of what these might be?
