Rockwood Posted January 25, 2020 Share Posted January 25, 2020 I think this looks like bone from the Morrison formation. Link to comment Share on other sites More sharing options...
jpc Posted January 25, 2020 Share Posted January 25, 2020 the blueness also suggests Niger, but there isn't much of that material out there. The blue and the ochre colored coating I see on the second photo suggest South Dakota White River Fm. Not dinosaur, but mammal. 1 Link to comment Share on other sites More sharing options...
Haravex Posted January 31, 2020 Share Posted January 31, 2020 I've seen worn bone fragments this colour also from el mers formation in Morocco so colour is nothing to go by, to id any further a location will be needed. Link to comment Share on other sites More sharing options...
Pemphix Posted January 31, 2020 Share Posted January 31, 2020 In Germany vivianit making the blue colour of some triassic vertebrate fossils (known from Buntsandstein-Formation and upper Keuper-Formation; early and late triassic age). So colour is nothing without location.... There's not much diagnostic signs on this piece, i think ID will be problematic even with location though.....

Rockwood Posted January 31, 2020 Share Posted January 31, 2020 The tags say likely Utah area. Morrison country, no ? Link to comment Share on other sites More sharing options...
