Africa is full of bats, but their fossils are scarce – why these rare records matter

      By Mariëtte Pretorius, University of the Witwatersrand   Africa is home to more than 20% of the world’s bat population. There are over 200 species to be found on the continent. South Africa is particularly diverse, with 72 bat species. I am a zoologist who has studied bats for many years. Recently, while doing some reading about South Africa’s fossils, I started wondering about bat fossils. Given […]

Fossil beetles found in a Botswana diamond mine help us to reconstruct the distant past

    By Sandiso Mnguni, University of the Witwatersrand   When most people think of fossils they probably picture bones. But there’s much more to the global fossil record: plants, shells, minerals and insects. The study of fossil insects is called palaeoentomology. Palaeoentomologists like myself seek out and study fossil insects that were trapped in mud which later became rock sediments, and those found in amber (tree resin). Very few deposits […]

Duckbill dinosaur discovery in Morocco – expert unpacks the mystery of how they got there

Sixty-six million years ago, when duckbills suddenly appear in Africa’s fossil record, the world’s land masses formed a series of islands. A seaway divided eastern and western North America; Europe was an archipelago. South America, India, Australia and Madagascar were all island […]

Morocco dinosaur discovery gives clues on why they went extinct

    By Nicholas R. Longrich, University of Bath   66 million years ago, the last dinosaurs vanished from Earth. We’re still trying to understand why. New fossils of abelisaurs – distant relatives of the tyrannosaurs – from north Africa suggest that African dinosaurs remained diverse up to the very end. And that suggests their demise came suddenly, with the impact of a giant asteroid. The causes of the mass […]

Tropical forests share similar mix of common and rare tree species, study shows

Butler By Liz Kimbrough via Mongabay A new study has for the first time identified the most common tree species in the tropical forests of Africa, the Amazon and Southeast Asia — and their similarities have surprised scientists. “The [study] shows some uncanny similarities among the world’s great tropical rainforests,” said tropical ecologist Bill Laurance, a co-author of […]
