The discovery of a new pterosaur species, Melkamter pateko, in Argentina suggests that pterodactyloids originated earlier than previously believed—about 178 million years ago during the late Early Jurassic. This species, identified by researchers Alexandra Fernandes and Prof. Oliver Rauhut, reveals features typical of advanced pterodactyloids, predating its closest relative by approximately 15 million years. Unlike most known pterosaurs from marine environments, Melkamter was found in an inland habitat and likely fed primarily on insects rather than fish. This indicates a possible inland origin for pterodactyloids, challenging the notion that they primarily emerged near coastal regions. The evolutionary significance of this find lies in understanding the diversification of early pterosaurs; it suggests that their adaptation to catching highly mobile prey, like flying insects, may have contributed to their success. This discovery emphasizes the importance of Southern Hemisphere fossil sites in enhancing our knowledge of pterosaur evolution. Overall, Melkamter pateko provides a crucial insight into the early evolution of pterosaurs, expanding the narrative of their development as the first vertebrates capable of powered flight.
