Ptychodus04 Posted July 30, 2015 Share Posted July 30, 2015 I just took a trip up to the Weminuche Wilderness (southwest Colorado) for some camping and high altitude asphyxiation. On the way, we stopped off at the scenic overlook at Molas Pass. Being the rockhound I am, I got bored quickly with the scenic views and began inspecting the rock outcroppings. I found several crinoid pieces, brachiopods, and a few oddities yet to be identified. My question is... does anyone here in the Borg know the age/formation of the limestone at Molas Pass? Marine fossils at 10,899 feet! That's some serious uplift.

Auspex Posted July 30, 2015 Share Posted July 30, 2015 The Laramide Orogeny began ~80 MYA, and ended ~55MYA, and the southern Rockies pushed through/lifted Pennsylvanian & Permian rocks.

Eocenecarnage Posted July 30, 2015 Share Posted July 30, 2015 I was on a fossil trip to McCoy, CO. I found crioid stems, brachiopods, nautiloids, shark teeth (Petalodus), and petrified wood. They are from the middle Pennsylvanian Period, around 300 million years ago. They are from the marine/terrestrial Minturn Formation. I found them in late June 1: Crinoids (Isocrinus?) 2: Brachiopods (Aquaspinifer, Composita) 3: Cephalopod (Pseudorthoceras) Link to comment Share on other sites More sharing options...
ZiggieCie Posted July 30, 2015 Share Posted July 30, 2015 11,000 feet up. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted July 31, 2015 Author Share Posted July 31, 2015 Thanks to all. This helps. Coming from my house at a staggering 556 ft. elevation, Molas Pass was quite different. Stony Pass at 12,650 ft was staggering (literally). I got out of the truck to take a picture and nearly fainted from lack of O2. I felt like Ziggy's emoticon!!!
