Africa’s Dinosaur Discoveries – Five Essential Reads

Few prehistoric creatures generate as much excitement and awe as dinosaurs. Whether it’s the & quot; tyrant & quot; T-Rex or a slim-necked Brachiosaurus, people are fascinated by these creatures that dominated landscapes all over the world – including across the African continent – hundreds of millions of years ago.

The dinosaurs are long gone (though we’re still surrounded by their direct descendants, birds). But researchers are still hard at work piecing together the fossil record to create a fuller picture of how dinosaurs lived, walked, ate and raised their young. Their discoveries offer a glimpse into ancient landscapes, helping modern scientists to better understand today’s climates and ecosystems.

The Conversation Africa has showcased a number of dinosaur finds on the continent. Here are five essential reads:

A rich record

Africa is widely acknowledged as the birthplace of humankind. But less attention is paid to its incredibly varied fossil record. Many of the planet’s most important life forms originated on the continent: bacteria-like organisms; many dinosaur species and, of course, primates – including humans. Even the rocks on the continent are among the oldest in the world. Some of them date back more than three billion years.

That’s what prompted Julien Benoit to create a syllabus for his palaeontology students that centered African fossil discoveries rather than focusing on finds from elsewhere in the world.

Hidden in plain sight

Many museums and universities keep extensive fossil collections. Their contents have been studied, labeled and cataloged. Sometimes, however, they hold secrets that can only be uncovered through a combination of scientific hunch and cutting-edge technology. That’s how Kimberley EJ Chapelle discovered and described an entirely new species: Ngwevu intloko (& quot; gray skull & quot; in isiXhosa).

A giant African dinosaur

Researchers are constantly rewriting the fossil record thanks to new discoveries. Dinosaurs’ fossilized footprints are a useful tool for this work, as evidenced by a – literally – gigantic find in Lesotho.

It was previously thought that ancient southern African landscapes were dominated by small and agile two-legged carnivorous dinosaurs called theropods. But Lara Sciscio and her colleagues’ study in Lesotho unexpectedly revealed that very large carnivorous dinosaurs with an estimated body length of between 8 and 9 meters (or 26 feet) – that’s a two-storey building or two adult rhinos nose to tail – lived in the region too.
