Wooly mammoths went extinct later than you think — some were even alive the same time the pyramids were being built!

In 1990, a group of researchers dated the remains of some dwarf mammoths that had been discovered on Wrangle Island. The researchers were able to place the remains in the time period of 7390-4740 BP, about 5000 years after the last known date of mammoths on the Eurasian continent.

This discovery was remarkable not only because of the date, but because the scientists were able to track the evolution of these mammals on the island. These mammoths survived so much longer that they were actually on earth during the time of the building of the pyramids.

The reason these particular mammoths were able to survive was that the environmental conditions on Wrangle Island during that time were suitable for mammoths to live in. Wrangle Island is located in the northeast corner of Siberia.
