flag Fossil eggshells reveal ancient crocodiles may have lived in trees and hunted from above, unlike today's species.

flag Fossilized eggshells from southeastern Queensland, dated to 55 million years ago, suggest ancient mekosuchine crocodiles may have been semi-arboreal, possibly hunting from trees like "drop crocs" rather than just from water. flag Unlike modern crocodiles, these extinct reptiles lived in forests, occupied diverse ecological niches, and nested near lake margins. flag Evidence from eggshell microstructure and fossil remains indicates they were terrestrial, adapted to land, and thrived before modern crocodiles arrived 3.8 million years ago. flag Their decline is linked to climate change, drying landscapes, and competition. flag The study highlights eggshells as a valuable source of information on ancient animal behavior and environments.
