A new frog species from the Ice Age has been found in the La Brea Tar Pits in Los Angeles. This new species is called Spea labrea. The Ice Age ended about 11,700 years ago, and many of the animals that lived then are thought to have disappeared 3 to 6 thousand years ago. The discovery was made by Dr. Alberto Cruz, who was not looking for a new species but found it while re-examining collections. At first, he thought it was a modern frog that was sick or hurt, but then he realized it was actually a frog from the Ice Age. The La Brea Tar Pits are a famous place where fossils of big animals like mammoths and saber-toothed cats have been found. This discovery is the first extinct amphibian found in Los Angeles and the second Ice Age amphibian found in North America. Scientists think that small animals like frogs can tell us more about the past than big animals. This is because small animals don't travel as much and are more sensitive to their environment, which can help scientists learn about climate change. Did you know that frogs rarely leave behind fossils because their bones are very delicate? But in some places like the La Brea Tar Pits, it's possible to find frog fossils. This discovery will help us learn more about the animals that lived during the Ice Age. Scientists will keep studying this new species to learn more about it.
