Osbornodon iamonensis is an extinct species of hesperocyonine, a predecessor of modern dogs that were endemic to North America and which lived from the Oligocene to Early Miocene epoch 23.6—16.3 Ma and existed for approximately 8 million years.[1] It was named for Lake Iamonia in northern Florida. Fossils have been found in Florida and Nebraska. In the Thomas Farm Site in Gilchrist County, Florida, it is the most common carnivore found in that area.[2][3]
