Thomas.Dodson Posted December 3, 2020 Share Posted December 3, 2020 It mostly boils down to the minerals it picked up during fossilization from the surrounding sediment. Iron-rich sediments produce more orange/red/brown stuff, phosphate produces the rich black stuff. Link to comment Share on other sites More sharing options...
hemipristis Posted December 4, 2020 Share Posted December 4, 2020 hello! Very nice teeth! Who's your dentist? lol The bluish tooth is indeed Galeocerdo, but I would venture G. cuvier. G. aduncus tends to be smaller and not nearly as robust. An excellent tiger. 'Those who cannot remember the past are condemned to repeat it.'
