Newly discovered oddball amphibian fossils could reveal clues about the prehistoric LA climate - CNN

Researchers have identified a new extinct species of spadefoot toad, Spea labreae, from fossils found in the La Brea Tar Pits. The discovery, hidden in a 1929 collection, offers new insights into the prehistoric climate of Los Angeles.
Why it matters
This discovery demonstrates the value of re-examining historical fossil collections to better understand ancient ecosystems and climate change.
In the heart of urban Los Angeles lie the La Brea Tar Pits, a group of natural asphalt seeps made famous by the millions of ice age fossils preserved within the bubbling, dark pools of goo. Excavations of the pits have yielded bones of species that once roamed the area tens of thousands of years ago, including giant mammoths, mastodons, saber-toothed tigers and dire wolves. But large mammals aren’t the only window into history that the asphalt has provided. Now, scientists have discovered the first extinct ice age amphibian from Los Angeles, a spadefoot toad named after the tar pits: Spea labreae. The findings are reported in a study published Wednesday in the Journal of Vertebrate Paleontology. The newly discovered toad is only the second extinct Pleistocene (2.58 million to 11,700 years ago) amphibian from North America to ever be found, according to the study’s authors.
