connorp Posted January 19, 2020 Share Posted January 19, 2020 It would help to know where it was found. Link to comment Share on other sites More sharing options...

iliafes Posted January 19, 2020 Author Share Posted January 19, 2020 Location is north New Mexico. Link to comment Share on other sites More sharing options...
Shamalama Posted January 20, 2020 Share Posted January 20, 2020 Looks like a fossil reed to me, but a more detailed location would be helpful. A county, or nearby town. North New Mexico is a large area and covered with lots of rock from different ages. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

iliafes Posted January 20, 2020 Author Share Posted January 20, 2020 It is Chama river canyon near Abiquiu. Link to comment Share on other sites More sharing options...
Shamalama Posted January 21, 2020 Share Posted January 21, 2020 Ok, That narrows things down a bit. Below is a geologic map of the area from Google Earth and the USGS. The light blue/teal colored rocks are Oligocene Santa Fe Group. The Dark Purple near the top is Paleogene aged units. The greeninsh tan areas are Chinle group which is Triassic aged. And the red areas are Morrison formation which is Jurassic in age. Does the area you found that rock in fall into one of those rock units? -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Kato Posted January 21, 2020 Share Posted January 21, 2020 Given the wild geology and the probability you found it near the river bottom the specimen could have washed in from anywhere. Did you find the actual formation itself? I know the canyons can get quite deep in places with hundreds of feet of exposure. From the photo, I get more of a calamites vibe for the biggest fragment.

iliafes Posted January 21, 2020 Author Share Posted January 21, 2020 This region is a little bit to the west from Abiquiu. Here is the surrounding map. Close to the road. Likely deep in Triassic. Far from the river flood-affected area, so could not be washed from the older sediments. Link to comment Share on other sites More sharing options...

Shamalama Posted January 22, 2020 Share Posted January 22, 2020 Here is the paper you found with a link: Sphenophytes from the Carnian (Upper Triassic) of Lunz am See (Lower Austria) CHRISTIAN POTT, HANS KERP & MICHAEL KRINGS I would go with the Chinle group for the local geology which is Middle Triassic. Neocalamites might be a good match as that exists from the Permian to the Jurassic. There is a paper called An Upper Triassic upland flora from north-central New Mexico, U.S.A. that may be of interest, but it is behind a paywall. Keep in mind that the upper slopes of that area is Jurassc aged rock (dark green and magenta). 2 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.
