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

Was found while paddle boarding in lake water. Just curious what it could be? Never used this site before but any help would be greatly appreciated. Spherical in shape all the way around. Both horizontal and vertical lines around it but mainly the really close horizontally striped lines all the way down and around the piece

Hi again everyone! I have a small fossil from a unit of lacustrine laminated silt from here in Saskatoon from the very late Pleistocene or early Holocene. The unit directly overlays a unit of till from the Wisconsinan glaciation. The unit contains carbonized plants stems, some of which are filled with wood boring beetle larva frass, diatoms, and burrows similar to Cruziana. In one of these hollowed-out burrows, I found this fossil, which is approximately 0.5 mm in length. It is composed of many extremely small carbonized plant fragments, all arranged horizontally from longest to shortest. I have no suggestions to explain how such an arrangement could occur through abiotic means, and the fossil bears a striking resemblance to caddisfly larva cases, many of which are composed of plant fragment arranged horizontally. I have attached some photos taken through a microscope lens on an iPhone. In hopes of accounting for the rough image quality, I have included numerous angles and degrees of brightness to help illuminate the arrangement of plant fragments. Any help confirming the caddisfly diagnosis or directing me from my incorrect guess to a correct one would be greatly appreciated!

Hello! I registered to get the privilege to see pictures, thought I should introduce myself. I live on about 6 acres in the Texas Hill Country- which means- lots of limestone. Jonestown is about 30 miles from the city center of Austin- really a suburb of Austin, at this point. I do find lots of mollusk shells in the rocks, and I'm interested in learning techniques that may help my searches be more fruitful, both on my own property and when I hike around the area. Most recently, I've been interesting in walking over the exposed lakebed of our local reservoir/lake, Lake Travis, which has been at historic lows, even though it has risen a few feet in recent weeks, I'm sure in the 70 or so years since the lake was built, many things have had the opportunity to wash down from the surrounding hills. I figure I'll mostly be a lurker/observer, but I will try to share some of my more interesting finds. Matt
