ID please? Ordovician (possibly), Southern Ontario, Canada

5.thumb.JPG.fcc2ac9f196a7c474c8740a38075f2d6.JPGHello. The attached photo shows two rocks found in Toronto, Southern Ontario, Canada, at Mimico Creek. I juxtaposed the two because it seemed to my amateur eyes that the one on the left might have some similarity in structure to the two "mallet-shaped" structures in the rock to the right.

 

Any help in ID'ing these would be greatly appreciated.

Welcome to the Forum. :)

 

These appear to be trace fossils of some type. 

I found this picture of an Ordovician aged specimen online, with similar structures.  :)

Dumbbell-shaped burrows are referred to the ichnogenus: Bifungites 

 

Here is an excellent paper:

Bifungites cf. halli from the Ordovician (Caradocian) Trenton Limestone of the Quebec City Area.

Thanks, this is very helpful, if also somewhat mysterious, these burrows ...
