Do Africa’s Mass Animal Migrations Extend Into Deep Time?

Africa is home to some of the world’s most spectacular animal migrations, such as the annual movement of wildebeest and zebras across the Serengeti.

These migrations are well-documented in modern times, but researchers are now asking whether these patterns extend far back into the past.

The article explores whether ancient animals in Africa migrated seasonally over long distances, similar to today’s movements.

To investigate this, scientists study fossilized animal teeth, which preserve chemical traces of the environments the animals lived in.

By analyzing these traces, researchers can determine whether ancient animals traveled widely or stayed in one place, shedding light on how ecosystems and animal behavior have changed over thousands or even millions of years.
