Hi! Amateur hour here! I know nothing, but I love attempting to locate and identify marine fossils, especially in places far away from any body of salt water.
I made a trip to New Mexico this past week and found some awesome fossils! Driving east on I-40 from Santa Fe, I stopped in Santa Rosa. Southeast of the city, there is Highway 156, and there are some great pull-offs a couple miles from the Interstate. I attached a picture of the fossil site guide I was using and a couple pictures of the fossils I was hoping to identify. The fossils were on the ground, no digging was done. No water nearby. The closest identifiable large rock seemed to be limestone (I think), but this was found amongst a ton of rock litter of different types.
Santa Rosa is a city in and the county seat of Guadalupe County, New Mexico, United States. It lies between Albuquerque and Tucumcari, situated on the Pecos River at the intersection of Interstate 40, U.S. Route 54, and U.S. Route 84. Elevation is 4,616ft.
