Hi guys I found this trace fossil some days ago and I find this fossil a bit puzzling. I have no certainty as to what creature could have made this. This fossil is from Mimico Creek, Toronto, Georgian Bay Formation, Humber Member, late Ordovician.

I see some sort two parallel burrows. What do you guys think?

They are arthrophycid burrows.  This paper has a few figured examples of Palaeophycus for comparison.
