Another hunt recently with more E KS ‘glacial’ material. Posting this on behalf of my hunting partner. My novice guess is equus, but I’m not sure. If it is equus, got any species ideas? Thank you so much, I really appreciate the help!

A short post today, just wanted to upload this interesting Rhizocorallium (?) I found on my most recent fossil hunting trip! It’s still the dead of winter here in Saskatoon, but we had a warm snap recently and I was able to hike out to a local glacial silt exposure and found it. Hoping to return to this site soon and hopefully find more!

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

Found by a friend on a Southern Minnesotan river gravel bar. Sediments in the area include everything both glacial till deposits and cretaceous sea mudstone and sandstones. although, I suspect this is modern.

Hello! Thank you all for taking the time to read this and (hopefully!) help me identify a very interesting find from Saskatoon! I was on a fossil hunting trip to a local exposure of Pleistocene glacial lake sediments in Saskatoon, and I took home a few samples of it to review later. While looking through one piece (the material is silt but breaks like a rock and is somewhat laminated), I saw this very strange shape. Attached are a few images, some simply in situ, others through a microscope. My apologies if the image quality is not ideal, I do not currently have any better equipment. There are a few images with my fingernail in frame to give you a sense of scale; this thing is very small. It is a kind of dome shape adorned with concentric rings of linked “nodes.” When looking at it, I knew it couldn’t be a pebble or partially buried rock. The thing it reminded me the most of was a Ptychodus tooth or other fish tooth plate, but the “dome” the nodes sit upon is penetrated open in one spot and is hollow. While I suppose this doesn’t rule tooth out, it does make me doubt that possibility. In addition, the nodes appear to resemble fish scales, especially ganoid scales, as some are rhomboidal in shape and all have the glassy coating those scales tend to have. There is also what appears to be a bone fragment near the dome. This is where my own suggestions end, I have no other ideas as to what this weird thing might be! Simple confirmation of the nodes as fish scales would probably satisfy me, but identification of them as ganoid would be even better. Please let me know if I can provide any extra clarification! Thank you!

Hi, I'm geologist from Poland, and I found trilobite fossil at work. Pygidium length and width are about 1,5 cm. It is from glacial aggregate; from Sweden (maybe Gotland). Fossil is from Cambrian - Silurian limenstones (perhaps Ordovician). I can't identify this kind of trilobite. Pygidium is little different. Pleura furrow is double in half or less length. The right pleura is further in limestone, and is longer 2-3 mm. Last axial ring seems like connect with upper axial ring. Thanks for any help and suggestions. Right pleura:

My only true "questionable" find whether it is something or not. I love learning about geology, that said after we purchased 3 acres on land which was under glacial units (Puget lobe in WA state, possibly Pleistocene) I dug a hole near what would have been a bank however many thousands of years ago (16,500 years ago would have been glacial outwash). I crack rocks open to see mineral composition. This was found slightly above (maybe 1'-2'), what I would label the alluvial line, but I am very much an amateur when it comes to defining specifics. Google fish fossils and there is nothing like it, I personally see clear and distinct fin outlines. BUT that is why I would LOVE to hear your feedback and any thoughts! This "fish outline" is small, 3.5" x 1". But if a fish i would think pretty rare find based on our locations climate/environment. Thank you for your time!

Hi! My dad and I went to look for shark teeth on the beach, we found a few. My dad picked up this rock which we both find very interesting, but I just can't seem to place it. It was found on melkbos beach where pleistocene fossils are found. Any help would be appreciated. Thanks.

Found on river gravel bar in Sothern Minnesota. I know its a partial tibia - any ideas on species? Sus maybe? Sediments in the area range from cretaceous to holocoen with a good amount of Wisconsin lobe glacial till. Previously we have found bison, mammoth, and ancient horse...

Any ideas as to what this might be? Thinking could be wood remnants, maybe petrified or partially so? Northwest PA, lots of glacial debris in area.

Did subglacial meltwater create Martian channels and valleys?
Oxytropidoceras posted a topic in Geology
The below article is discouraging as far as the possibility of Martian fossils. Early Mars was covered in ice sheets, not flowing rivers, researchers say University of British Columbia, August 3, 2020 Summary: "A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new research.'

Hello folks. I'm back after an extended break. I've found some really cool fossils on my land in southern Missouri, Texas county, USA. Just a few miles south of cabool. A seasonal stream flows through my land exposing some cool finds, not to mention- the heavy rains are washing the topsoil away. From the hundreds of artifacts I've collected, this spot must have been an indigenous settlement. My best guess is that this item was in the hands of those early Americans. I can see why, this is my 2nd most favorite of the collection. Please help me identify what this is. Any help would be greatly appreciated. FYI, I have overcast skies at the moment and very limited internet access. These pics are the best I can do. Mm measurements are roughly 66mm x 38mm x 25mm

July 23,2019 Its been so hot working outside all week that today's fossil hunt in 70 degree temps felt cool. It was quiet in the stream (besides the sound of wildlife) when I got there in the AM and stayed that way all day. I didnt want to disturb the scene with me pounding on rocks so I surface collected and covered a large area of the stream. Along the sides of the stream are glacial erratic boulders, stones, and gravel. The tabulate corals (Chonostegites clappi, Favosites winchelli, Favosites sp.) I pictured in this post were found among these glacial rocks. In one gully off the stream I noticed a large boulder of Waterlime. I have found parts of Eurypterids in these displaced Silurian rocks before. Today I found a partial Eurypterid on one of these boulders but had to leave it where I found it. Too big and way too far to haul back. Happy Collecting, Mikeymig

Howdy all! I found this and was hoping to put a name to it. This was found in a drainage ditch in South bend Indiana and is glacial till. Thank you for all you do!

Would you be able to ID this for me. It was found in South Bend Indiana so chances are it isn't from around here but dropped off by a glacier a few years back. Also, I wet it down so the features can be better seen. Any ideas? Thank you.

This was found in an esker near Bingham, Maine. Most of the rocks in the line of glacial scour are mid Devonian and below, marine formations. It looks like the left side of a cephalon, labeled as a librigenea in the morphology section on Wiki .

This was found in South Bend Indiana in a storm water ditch. This was probably dropped off by a friendly glacier from up north. It is 6 cm long and 4 cm wide at the top and 3 cm at the bottom.

Please help identify the fossil below. It was found in glacial till/drift in South Bend, Indiana. Approximately 8cm across and 4cm wide. Please note the hangnails in the third picture. I've never had a manicure but I am now debating. Thank you for your help and understanding.

I was wondering if someone could help me identify this fossil found over the weekend. It was found in South Bend Indiana. Because it was found in Northern Indiana, the fossil isn't from around here and was probably deposited by a glacier from somewhere up north. It is approximately 12 cm at its longest point and about 4 cm wide. Thank you for your help!

I found this in a gravel pit at the south east end of Moose Mt. in Maine. The fossils I find there have been exclusively marine invertebrates so I was trying to see perhaps scaphopod traces. The dark edges were hard to explain until I realized that this is what the plants that I find up in far north eastern Maine look like except in isn't flattened. Ya think ? oops end view pending.
