Well with the last year of moving and renting and moving again, I haven't had much time to do much of anything on the fossil front. The Pictured Cliff Sandstone formation, Late Cretaceous near Durango, Colorodo. Spotted these large rock faces with ripple marks and decided to be a geology nerd and scramble as far up the slope as possible to snap a few photos. These ripples were likely deposited at the edges of the Interior Seaway, Late Cretaceous. In 10m of water. At least, that's what the paper suggests. (Depositional Environments of The Pictured Clif
Is this even a fossil? Ichnofossil? I'm stumped by this weird pattern. I found this ironstone in my parents' gravel driveway. Gravels were recently obtained from the local sand pit company here in Salina, KS., so I'm pretty sure this stone was transported in the river from Kiowa or Dakota formation (Albian) before being deposited.
Is this a burrow ? I'm sort of leaning toward it being a fluid or gas venting feature myself. It was found on the shore of Moosehead Lake just south of where the fossiliferous, upper Silurian, Forks turbidite crosses it. The breaks are likely caused by the thrust of ice as it forms and expands against the shoreline in that spot. Car sized boulders can be displaced several feet by the force. The blue line indicates roughly the position of the hole. It passes all the way through, with a slight bend and constriction in the center.
Just got back and am beat from a day at Arkona. This one is a bit strange. Just when I think I've seen every odd pattern, ichnofossil, mineralization, and concretion type in the Widder shale, I get a curveball. Or should I say a snowflake?. specs: Mid Devonian (Widder Fm). Arkona, Ontario. About an inch. I can't seem to find it, so this pic was taken in the field. I might have lost it.
