Leptoptilos lüi is an extinct species of large-bodied Leptoptilini stork that existed during the Middle Pleistocene. Along with Aegypius jinniushanensis, L. lüi is one of several new species of extinct birds discovered at Jinniushan, Liaoning, China.[1] The extinct stork is named after Professor Zun-e Lü.[2]
Extant members of the genus Leptoptilos are today found only found in the African and Asian tropics.[3] L. lüi is the only member of Leptoptilos from the Pleistocene so far to have been discovered outside of its modern range.[3]
Description
L. lüi is one of the largest Leptoptilos on record and might be larger than Leptoptilos titan and Leptoptilos robustus.[lower-alpha 1][4] The humerus and proximal phalanx are longer and more robust than those of any other Leptoptilos on record.[2]
With very long wings, L. lüi was probably a good flyer that mainly relied on gliding and soaring on the thermal air currents available then, as the climate conditions in the region during the Middle Pleistocene was a lot warmer and more humid.[3] L. lüi most likely relied on scavenging from Pleistocene megafauna for the bulk of its food source.[3] The disappearance of Pleistocene megafauna and climate change are likely the primary causes of its extinction.[3]
