This color contrast, arising from the fossilization process and mineral absorption, allows for the discrimination of these specimens from the surrounding environment.
-
Manganese Dioxide Deposition
The dark coloration of fossilized teeth is often attributable to the deposition of manganese dioxide (MnO2) from surrounding sediments. Over geological time, manganese ions in groundwater precipitate onto the tooth enamel and dentin, forming a dark brown to black coating. This process is particularly prevalent in anaerobic conditions, where manganese is more soluble. Areas with high concentrations of manganese in the soil and groundwater tend to yield darker specimens, facilitating easier identification against lighter backgrounds.
-
Phosphate Mineralization
In addition to manganese deposition, phosphate mineralization contributes to the alteration of tooth color. Apatite, a calcium phosphate mineral, is a primary component of both tooth enamel and bone. During fossilization, apatite can recrystallize or be replaced by other phosphate minerals, altering the tooth’s original color. The resulting color can vary depending on the specific mineral composition and the presence of trace elements. The dark hues from phosphate mineralization often present a greater contrast to its environment.
-
Substrate Contrast Enhancement
