A Wealth of Trace Fossils from Saskatoon, Saskatchewan!
Pseudogygites posted a topic in Fossil Hunting Trips
Another day of great finds in Saskatoon! This time, some trace fossils. With my wonderful collaboration with the University of Saskatchewan's Museum of Natural Sciences still continuing, recently I have been very lucky to make multiple trips out to a beautiful site just outside the city of Saskatoon where massive deposits of glacial lake silt are exposed. This silt produces pristine grass and other plant fossils in abundance (I'd like to make a post about them soon as well), but also seems to be teeming with various invertebrate trace fossils. All are very small (under 1 centimetre wide). I've attached some of my best pictures below. 1 - 6: Overlapping Planolites sp. closeups 7 - 11: Edaphichnium sp. 12 - 14: Taenidium sp. closeups 15 - 16: Taenidium sp. wide shots 17: Taenidium sp. closeup- 3 replies

Hi there! First time poster, so I apologize if I'm lacking information. Also, my phone died on my way to the location, so I couldn't take pictures of the area I found them in. I tried to doodle a picture, but I'm no artist. Today I decided to check out a beach I had heard about near Port Angeles on the Olympic Peninsula of Washington State. . On this beach, there is a section of mudstone/sandstone about 60 feet tall and 100 feet long. At the base of the slope was a boulder(also sanstone/mudstone) about 6 feet tall and 4-5 feet around. It must've recently fallen because it was crumbling more and more just from looking at it. Right in the middle of the clump there was some sort of long, lumpy fossil(thought it was, sounds like it's not ;)). I have no idea what it could be. I've googled "lumpy dinosaurs", "lumpy whale vertebrae", and a few more embarrassing amature terms, all to no avail. If anyone could help me identify these, I would be EXTREMELY grateful! I've definitely caught the fossil/rock hunting bug and am really excited about finding these. If any other pictures/measurements would be helpful, just let me know. The largest piece is about the size of a volleyball. Edit** forgot to add, it was found in either lower tertiary sediment, or quaternary sediments. Sort of on the border of the two according to my map Edit #2** Just did a little more researching on the area, and it is part of the Twin River Formation. "Upper member, massive to thin-bedded mudstone and siltstone. Olive gray to greenish gray mudstone, claystone, and siltstone are poorly indurated and contain thin beds of calcareous claystone and a few thin to very thick beds of massive calcareous sandstone. Spherical, cylindrical, or irregular shaped calcareous concretions common"
