Auspex Posted December 30, 2013 Share Posted December 30, 2013 These are Ptychodus teeth; very nice!

Fossildude19 Posted December 30, 2013 Share Posted December 30, 2013 (edited) These appear to be Ptychodus sp. crusher teeth. Not sure of the age of the sediments in that area, but Ptychodus ranged from the Cretaceous to the Paleogene. Regards, EDIT: Outdrawn by the quickest ID in the east. EDIT 2: I see the Mancos shale is from the Upper Cretaceous.... so there you are.

Pilobolus Posted December 31, 2013 Author Share Posted December 31, 2013 Was kind of hoping these were echinoderm spines or something; although cool, can't take vertebrate fossils from this site... Thanks for the positive ID, however. Link to comment Share on other sites More sharing options...
Pilobolus Posted January 6, 2014 Author Share Posted January 6, 2014 Another unknown imprint from the Rio Puerco site...micro lichens seem to like these impressions as a way to collect moisture, I'm guessing... Link to comment Share on other sites More sharing options...
PFOOLEY Posted May 16, 2014 Share Posted May 16, 2014 Another unknown imprint from the Rio Puerco site...micro lichens seem to like these impressions as a way to collect moisture, I'm guessing... Scaphites sp. impression (possibly whitfieldi; Cobban 1951)...impressions such as these are common in the mid Turonian (Late Cretaceous) aged Juana Lopez Sand Stone member of the Mancos shale. 1 "I am glad I shall never be young without wild country to be young in.

erose Posted September 16, 2014 Share Posted September 16, 2014 Was kind of hoping these were echinoderm spines or something; although cool, can't take vertebrate fossils from this site... Thanks for the positive ID, however. If it's BLM and you know who the manager is ask them (in an unrevealing way, wink, wink) what the status of "common" shark teeth may be. They may have no problem with collecting them at all. And considering how many you found they appear to be "common". Link to comment Share on other sites More sharing options...
