Denis Arcand Posted June 20, 2022 Share Posted June 20, 2022 (edited) Can anyone tell me if these are actual fossils or just geological formations, although they look like fossilize plants to me, it would be very surprising to find fossilized plants from the late Ordovician period. both rocks were found in the Nicolet River Formation on the banks of the Richelieu river Edited June 20, 2022 by Denis Arcand Link to post Share on other sites
Kane Posted June 20, 2022 Share Posted June 20, 2022 I would say these are infilled burrows. I sometimes bumped into burrow layers in the Nicolet. 1 1 Link to post Share on other sites

Thanks!, that makes lots of sense, which brings me to another question, the burrows appear to be much larger than any type of brachiopod or bivalve I've ever found to date, what kind of other life form could dig such burrow in the Ordovician era?

abyssunder Posted June 20, 2022 Share Posted June 20, 2022 Maybe something close to Trichophycus? 1 Link to post Share on other sites

Denis Arcand Posted June 20, 2022 Author Share Posted June 20, 2022 I found this interesting link on trace fossils, and learn that trilobite also make burrows, so maybe that is what I found http://www.georgialifetraces.com/tag/trichophycus/ 1 Link to post Share on other sites
