The La Brea tar pits preserve way more than just mammoths, saber-toothed cats and dire wolves. Ancient frogs and toads can teach us more about what the climate was like 45,000 years ago. As Dr Emily Lindsey explained to IFLScience, a dire wolf fossil “doesn’t really tell you much about what the environment was like.” Known for the large, charismatic animals such as mammoths and dire wolves, La Brea fossil site provides an astonishing snapshot of life 45,000 years ago. But it is some of the smaller residents of this ancient ecosystem that have got scientists excited. Say hello to Spea labreae, a newly described Ice Age toad from the La Brea tar pits (yes yes, we know that’s tautological). The fact that you find something like a dire wolf at a site doesn’t really tell you much about what the environment was like. Emily Lindsey “This is the first extinct amphibian in La Brea, and is only the second extinct amphibian in all of the United States,” Dr José Alberto Cruz, the lead author of the study, told IFLScience. “It’s very, very uncommon.” “The problem is that bones don’t have [many] diagnostic characteristics in the case of reptiles or...
