Videos > Lazarus Taxa

Lazarus taxa are fossils that appear in certain rock layers, then disappear in higher layers, leading us to conclude that they went extinct. But then–like Lazarus in the Bible coming back to life–we find them reappearing in much higher rock strata, or even alive today. Learn more about some classic Lazarus taxa and their significance for the interpretation of the fossil record from this series of 2-minutes videos.
