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 {{Mya|24-16|million years}}.[http://paleobackup.nceas.ucsb.edu:8110/cgi-bin/bridge.pl?action=checkTaxonInfo&taxon_no=48335&is_real_user=1 Paleobiology Database: Osbornodon iamonensis]{{Dead link|date=April 2020 |bot=InternetArchiveBot |fix-attempted=yes }}. 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.{{Cite web|date=2017-03-31|title=Osbornodon iamonensis|url=https://www.floridamuseum.ufl.edu/florida-vertebrate-fossils/species/osbornodon-iamonensis/|access-date=2021-06-16|website=Florida Museum|language=en-US}}{{Cite web|date=2017-03-28|title=Thomas Farm|url=https://www.floridamuseum.ufl.edu/florida-vertebrate-fossils/sites/thomas-farm/|access-date=2021-06-16|website=Florida Museum|language=en-US}}
