Farmer Discovers Four Giant 'Ancient Armadillo' Glyptodont Shells In Dried-Out Riverbed

These four appear to be a group comprising two adults and two young animals.

Tests will be performed to attempt to establish how old they are, what sex they were, and - potentially - how they died.

At this stage, it is believed they are roughly 20,000 years old.

They'll have to be extracted using a digger, because the shells are so heavy.

This isn't the first time in recent years that Glyptodont shells have been turned up unexpectedly in Argentina.
