Yoda Posted January 11, 2019 Share Posted January 11, 2019 Hi, prob a newby question. But while I was trawling on the net, I noticed that Trilobites from different regions of the world are different colours. For eg: Morocco - black Russia - sandy brown China - sandy brown Is there a reason for this? MotM August 2023 - Eclectic Collector Link to comment Share on other sites More sharing options...
Darktooth Posted January 11, 2019 Share Posted January 11, 2019 It depends on what minerals were present during fossilization. 4 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Kane Posted January 11, 2019 Share Posted January 11, 2019 Setting aside the more rarefied scenario of chromatophores, much of the colour of the trilobite is contingent upon the specific mineral replacement of where it was deposited. For example, pyritized trilobites speaks to anoxic conditions with a suitable availability of sulphides in the mud. 5 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
DeepTimeIsotopes Posted January 11, 2019 Share Posted January 11, 2019 A lot of it has to do with what minerals they were fossilized with and the environment where they died. Some are replaced with pyrite making them gold/brass colored, some hematite making them black, or even blue and green from chlorite in some. 2 Each dot is 50,000,000 years: Hadean............Archean..............................Proterozoic.......................................Phanerozoic...........
