NATURAL TRAP CAVE, AN ICE AGE TREASURE TROVE: In 2014 a team led by Julie Meachen of Des Moines University and Alan Cooper of the Australian Centre for Ancient DNA at the University of Adelaide, re-opened the Natural Trap Cave in Wyoming with the goal of extracting ancient DNA from the mammal fossils and exploring faunal changes in the light of climate change over the last Ice Age and into the present. Over the last two field seasons the team has collected not only large mammal fossils but also large quantities of microfauna fossils (lizards, snakes, fish, frogs, birds, rodents, bats, and other small mammals) which can give us information on climate change at NTC through time.
