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

A newly discovered toad species, Spea labreae, is challenging assumptions about the Ice Age climate in Los Angeles. The toad, found in the La Brea Tar Pits, is the second Ice Age amphibian discovered in North America. The discovery of this spadefoot toad, which lived exclusively in the Los Angeles area, suggests that the climate during the Ice Age was more varied than previously thought.

The toad's unique characteristics and habitat preferences indicate that the region may have had more diverse microclimates. This challenges the prevailing notion of a uniformly cold and dry environment. The toad's presence in the tar pits, alongside other Ice Age fauna, provides a snapshot of the ecosystem during that period.

However, the exact implications of this discovery for our understanding of the Ice Age climate in Los Angeles are not yet fully understood. The toad's specialized adaptations and the specific conditions required for its survival raise questions about the broader environmental context. Scientists are now tasked with integrating this new information into existing models of the Ice Age climate.
