Avian fossils are the preserved remains of birds that lived in the past, providing critical evidence for understanding bird evolution and diversity. These fossils include bones, feathers, and even traces of behaviors like nesting and feeding, allowing paleontologists to reconstruct the lifestyles and habitats of ancient bird species. By studying avian fossils, researchers can trace the evolutionary lineage of birds, linking them to their dinosaur ancestors and uncovering how they adapted to various environments over time.
