Pterosaurs, the first flying vertebrates, had a significant impact on Mesozoic ecosystems, but their ground movement and terrestrial ecology are not well understood.
Research shows that pterosaurs had a diverse range of hand and foot structures, similar to modern birds, which indicates they adapted to various non-flying lifestyles, with early species showing traits for climbing and later ones for ground movement.
The evolution of ground-based locomotion in pterosaurs involved changes in anatomy, allowing them to exploit terrestrial environments and leading to new feeding strategies and larger body sizes across different lineages.
