Dinosaurs thrived for over 160 million years in Mesozoic ecosystems, displaying diverse
ecological and evolutionary adaptations. Their ecology was shaped by large-scale climatic …

Dinosaurs have attracted varying degrees of scientific and public interest since their initial
description in 1824. Interest has steadily increased, however, since the late 1960s when the …

Dietary preferences of extant reptiles can be directly observed, whereas diet reconstruction
of extinct species typically relies on morphological or dental features. More specific …

When studying living organisms, we are often interested in many different aspects of their
biology, including diet, habitat preference, physiology, growth, and how they fit into the …
