sharkysaurus Posted December 23, 2021 Share Posted December 23, 2021 I found these two neat little fossils in La Junta, Colorado. I'm not sure what they are but I have two guesses what they might be: barnacles or fish scales. I think it's from the Morrison formation but I'm not 100% sure! Any help would be appreciated Link to comment Share on other sites More sharing options...
Rockwood Posted December 23, 2021 Share Posted December 23, 2021 Are you quite certain it is in the rock ? I suspect it is a lichen, on the rock. Link to comment Share on other sites More sharing options...

Top Trilo Posted December 23, 2021 Share Posted December 23, 2021 La Junta is late Cretaceous, with formations such as the Niobrara formation, Carlile shale, greenhorn limestone, and Graneros shale. Those formations contain cretaceous marine fossils such as ammonites, shark teeth, marine reptiles, bivalves, etc. The nearest Morrison formation exposure is 20 miles to the south. 1 “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

I always thought its Late Jurassic, since the area I was fossil hunting at has footprints from allosaurus, apatosaurus and othe late Jurassic dinosaurs.

If you found this in the same area, than there is a good chance it is Jurassic. Here is a geologic map of the area. The yellow areas are recent Holocene deposits along the Arkansas River. The green area is Cretaceous, further south, the light blue is Jurassic Morrison Formation, purple is Triassic. The red dot is where known Jurassic dinosaur footprints have been found. If you are in that area (in the valleys and canyons) than you are right, it is the Morrison formation. 1 “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

Yes it is in the rock! I tried scraping it off and nothing came off. Link to comment Share on other sites More sharing options...
