The Pictured Cliffs formation - Durango, Colorado
Brett Breakin' Rocks posted a topic in Fossil Hunting Trips
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 Cliffs Sandstone, Late Cretaceous, Near Durango, CO.) This was as close as I dared in loafers, on a decent slope, along a busy highway. haha I did find what looks to be an ichno fossil nearby (the paper suggests Thalassinoides and Opbiomorpha ). The Fruitland Formation sits on top of the Pictured Cliffs so it could have come from either I suppose. More exciting finds are around the corner, I wait patiently. Cheers, Brett
