Discover the fascinating world of fossilized dinosaur poop, also known as coprolites, and its vital role in understanding ancient ecosystems. Learn how these unique fossils reveal insights about the diets and lifestyles of dinosaurs, offering a perspective often overshadowed by bones. Explore the meticulous process of identifying and studying coprolites, which unveil surprising dietary diversity among these prehistoric creatures. Uncover the evidence linking modern animal behaviors to their ancient counterparts through the ancient remnants of dung.
Fossilized dinosaur dung, or coprolites, provides critical insights into ancient diets and ecosystem interactions beyond what traditional fossils reveal.
Identifying coprolites involves meticulous analysis of their chemical composition and organic remnants, distinguishing them from ordinary rocks for ecological understanding.

The Significance of Coprolites in Paleoecology
Fossilized dinosaur dung, known scientifically as coprolites, plays a crucial role in understanding ancient ecosystems. Unlike traditional dinosaur fossils, which mainly provide insights into the physical traits of dinosaurs, coprolites offer evidence of animal behavior and dietary habits. By analyzing these remnants, scientists can gather valuable information about what dinosaurs consumed and how they interacted within their environments. Thus, coprolites serve as a window into the ecological dynamics of prehistoric life, shedding light on food webs and nutrient cycling.
Identifying Dinosaur Fossils vs. Coprolites
Determining whether a fossil is a coprolite or merely a rock can be a challenging task for paleontologists. Various characteristics are examined, including chemical composition and the presence of organic materials such as plant or bone fragments. This analysis can reveal feeding behaviors of dinosaurs, as coprolites may contain remains of other organisms they consumed, such as crustaceans or plant matter. Therefore, careful scrutiny and a detective-like approach are required to accurately classify these fossils and understand their implications for dinosaur diets.
Insights into Dinosaur Diets and Behavior
Research on coprolites has revealed unexpected dietary practices among dinosaurs, including the consumption of rotting wood. This finding suggests that some herbivorous dinosaurs may have ingested more diverse food sources to meet increased protein needs, perhaps during reproductive periods. Additionally, evidence of animals like dung beetles interacting with dinosaur feces indicates a complex ecosystem of decomposition and nutrient recycling. Such insights highlight the importance of these fossils in reconstructing the behaviors and diets of ancient creatures, offering a more nuanced picture of dinosaur life.
To gaze upon a full T. rex skeleton is to be transported back in time. Dinosaur fossils are key to understanding what these prehistoric creatures looked like, how they moved, and where they lived.
But there’s one type of dinosaur fossil that’s sometimes overlooked: poop. Its scientific name is coprolite. These fossilized feces are rarer than their boney counterparts, but they’re key to better understanding dino diets and ecosystems.
This all raises an important question: How scientists know if something is fossilized dino poop or just a rock?
At Science Friday Live in Boulder, Ira talks with Dr. Karen Chin, paleontologist and professor of geological sciences at the University of Colorado, Boulder to answer that question and much more.
