The evolution and systematics of Madagascar’s extinct elephant birds remains unclear. Here, the authors recover genetic, stable isotope, morphological, and geographic data from fossil eggshell to describe variation among clades, identifying cryptic

Abstract Natural history collections are often plagued by missing or inaccurate metadata for collection items, particularly for specimens that are difficult to verify or rare. Avian eggshell in particular can be challenging to identify due to extensi

The impact of late Pleistocene climate change on ecosystems has been hard to assess. Here, the authors sequence ancient DNA from Hall’s Cave, Texas and find that both plant and vertebrate diversity decreased with cooling, and though plant diversity

The controversy over the taxonomic identity of the eggs exploited by Australia’s first people around 50,000 y ago is resolved. The birds that laid these eggs are extinct, and distinguishing between two main candidates, a giant flightless “mihirun
