isurus planus hook makos

A silly question.

All come from the same sandy level or belong to different sandy levels with different hues?.

I know that these tones come from the minerals present in the surrounding matrix, but always I've been intrigued with the great variety of tones that show the enamel on STH.

Thanks in advance

All basically come from the same bone layer. The minerals surrounding the teeth give them the great colors. Iron, the reds and oranges, maganese the blues and grays. Thanks for the interest.
