Dinosaurs’ Secrets Might Be In Their Fossilized Poop

Rapid Burial

Rapid burial conditions play a crucial role in the fossilization of dinosaur feces, known as coprolites. Karen Chin explains that rapid burial, along with the right water and chemical conditions, can lead to mineralization within weeks 1. This process is more common in environments like lakes, where burial happens quickly, making coprolites from such settings less rare 2.

   

Mineralization

Mineralization of coprolites faces challenges, especially with herbivore feces due to low phosphorus content. Karen Chin notes that herbivore diets lack phosphorus, requiring external sources for mineralization 2. Additionally, identifying coprolites involves examining chemical composition and evidence of biotic material, such as chopped plants or bones 3.
