The Scimitar cat, Homotherium latidens (a.k.a. one of the species of sabertooth tigers) split from other big cat species about 22.5 million years ago and did not admix with other big cat species after that point, ancient DNA now tells us (along with information about other traits graphically described above).
The most recent example of one before they went extinct is from 28,000 years ago.
Very interesting. BUt I think the title "Saber Tooth Cat Ancient DNA Provides New Insights" would be more interesting.
