Went to Joshua Creek near Mississauga and got bitten by Mosquitoes! This creek yields its treasures very reluctantly. I looked at hundreds of rocks and brought back only six. One is an 'X' shaped burrow. Another has a bunch of wavy ridges through several layers which I presume are either geological or maybe fossil algae that is new to me. Also got a few 'bumpy' bryozoans, which I have taken to calling 'Parvohallopora' until I can figure out what they really are in Georgian Bay formation. Much of the area was packed with trace fossils...intensely detailed, but boring and with no sign of shells or any fossil life forms. The layer can be observed in place, extending for hundreds of meters, with nothing but burrows and little globs. At one point I found, to my surprise, that the broken shale pieces were pressed against a Queenston formation layer with their detailed surface against the flaky shale. That was surprising and unintuitive to me. I visited my traditional tiny outcrops, one with lampshells and the other with large branching bryozoans (flip side of a layer with large wave ripples). Fossil buddies were: toad, frog, cardinal, and 2 woodpeckers.
markjw posted a topic in Fossil Hunting TripsThere is a bit of Georgian Bay formation in my neighbourhood. It is littered with trace fossils and guarded by swarms of mosquitos. This area surrenders its treasures very reluctantly. There are a few little bryozoan pieces and not much else that I can see. The exception is a single outcrop from which I've pulled some sedimentary rock and found shell imprints. Some are quite wonderful, and there are several species. I think they might have these genus names: Ambonychia, Rafinesquina, Zygospira. The rocks also have all kinds of "colonies" in them, but I cannot identify them and they are not easy to make out.
