Reanalysis and experimental evidence indicate that the earliest trace fossil of a winged insect was a surface-skimming neopteran.
A recent description and analysis of an imprint fossil from the Carboniferous concluded that it was made by a mayfly landing in sediment at the edge of water. Here, I reanalyze that trace fossil and supply experimental evidence regarding wing traces and behavior. The thorax of the trace maker lacked structures characteristic of mayflies, but closely matches a modern neopteran insect family (Tae...
متن کاملDiversification in Adelomyia hummingbirds follows Andean uplift.
The Andes are known to have influenced speciation patterns in many taxa, yet whether species diversification occurred simultaneously with their uplift or only after uplift was complete remains unknown. We examined both the phylogenetic pattern and dates of branching in Adelomyia hummingbirds in relation to Andean uplift to determine whether diversification coincides with the chronological phase...
متن کاملInfluence of Andean uplift on climate and paleoaltimetry estimates
a r t i c l e i n f o Keywords: paleoaltimetry geodynamics paleoclimate stable isotopes Andes plateau Recent elevation reconstructions of the Andean Plateau suggest a rapid 2.5 ± 1.0 km rise of the central Andes between ~10 and 6 Ma. This rapid rise has been attributed to a catastrophic removal of a dense lithospheric mantle root beneath the Andes. However, these findings are based on the assum...

متن کاملBiting Midges (Diptera: Ceratopogonidae) from Cambay Amber Indicate that the Eocene Fauna of the Indian Subcontinent Was Not Isolated
India's unique and highly diverse biota combined with its unique geodynamical history has generated significant interest in the patterns and processes that have shaped the current distribution of India's flora and fauna and their biogeographical relationships. Fifty four million year old Cambay amber from northwestern India provides the opportunity to address questions relating to endemism and ...
