Dinosaurs occupied a range of trophic positions within ancient ecosystems, from primary producers to apex predators. Herbivorous dinosaurs, such as sauropods and ceratopsians, likely played a key role in shaping vegetation patterns and nutrient cycling. Carnivorous dinosaurs, such as theropods, played a top-predator role, regulating herbivore populations and maintaining ecosystem balance.

: By studying "hard tissues" (bones and teeth), researchers reconstruct dinosaur locomotion, posture, feeding habits, and reproduction. The Living Legacy

While comprehensive, the text is not without minor flaws.

Dinosaur paleobiology is the study of dinosaurs as living organisms, using fossil evidence to reconstruct their biology, behavior, and evolution. This guide outlines the core scientific concepts and practical resources for studying this field. Core Concepts in Dinosaur Paleobiology geokniga-dinosaur-paleobiology.pdf
