Daeodon fossil map
Where fossils of Daeodon have been found, shown on the Earth as it looked about 30 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 30 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al. (2021) plate model; positions are approximate. Open on the timeline map →

About Daeodon
Daeodon is an extinct genus of entelodont even-toed ungulates that inhabited North America about 29 to 19 million years ago from the Early Oligocene to late Early Miocene, making it the last known entelodont. The type species is Daeodon shoshonensis, described from a very fragmentary holotype by Cope. Some authors synonymize it with Dinohyus hollandi and several other species (see below), but due to the lack of diagnostic material, this may be questionable.
Another large member of this family, possibly larger than Daeodon, is the Asian Paraentelodon, but it is known by very incomplete material.
