Fossil-hunting expeditions to Tanzania, Zambia and
Antarctica provide new insights
Predecessors to dinosaurs missed the race to fill habitats
emptied when nine out of 10 species disappeared during Earth's largest mass
extinction 252 million years ago.
Or did they?
That thinking was based on fossil records from sites in
South Africa and southwest Russia.
It turns out, however, that scientists may have been looking
in the wrong places.
Newly discovered fossils from 10 million years after the
mass extinction reveal a lineage of animals thought to have led to dinosaurs in
Tanzania and Zambia.
