Weather warning: Bad weather killed giant ancestors of common animals
that roamed Europe
Ice Age megafaunal, such as giant oxen called aurochs and mammoths, which roamed across Eurasia and the Americas became extinct after a major increases in environmental moisture, according to the study.
The persistent moisture caused by melting permafrost and glaciers turned widespread glacial-age grasslands into peatlands and bogs, annihilating populations of large herbivore grazers.
Research led by the Australian Centre for Ancient DNA at the University of Adelaide, published today in Nature Ecology and Evolution, has revealed that ancient bones show evidence of environmental upheavals.
