Long before birds took their first flights, pterosaurs, a group of flying reptiles, dominated Earth’s skies. A recent study by researchers at the Bavarian State Collection for Paleontology and Geology (SNSB), led by Oliver Rauhut and Alexandra Fernandes, has shed new insights into the evolution of these fascinating animals.
The New Discovery
The research revealed the species Melkamter pateko, a pterosaur from the Early Jurassic (approximately 178 million years ago) discovered in Chubut Province, Argentina. This find is notable for pushing back the known timeline of advanced pterosaur evolution by 15 million years, offering crucial clues about the group’s diversification.
Unique Features
Unlike most Jurassic pterosaurs, which are generally found in coastal environments, Melkamter pateko lived inland. This adaptation suggests that pterosaurs may have evolved initially in terrestrial habitats, feeding on insects, in contrast to their marine relatives that fed on fish.
Advances in aerodynamics over millions of years, such as shorter tails and elongated wings, culminated in efficient fliers, including giants like Quetzalcoatlus, with wingspans exceeding 12 meters.
Importance for Paleontology
The discovery of Melkamter pateko highlights the relevance of the Southern Hemisphere continents in understanding the evolution of pterosaurs. According to Alexandra Fernandes, “this early specialization in hunting mobile prey, such as flying insects, may have contributed to the evolutionary success of pterosaurs.”
Furthermore, the study emphasizes the need for greater paleontological exploration in less studied regions, such as South America, which still holds important secrets about the evolution of prehistoric species.
Scientific Impact
Published in the journal Royal Society Open Science, the study reinforces the diversity and complexity of pterosaurs, highlighting their unique adaptations and the central role they played in the history of vertebrate flight. The research expands our understanding of these pioneers of the skies and inspires new efforts to unravel the mysteries of the Jurassic era.
