Mystacodon fossil map
Where fossils of Mystacodon 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 Mystacodon
Mystacodon is a genus of toothed baleen whale from the Late Eocene Yumaque Member of Paracas Formation (previously called as Yumaque Formation) of the Pisco Basin in southwestern Peru. It is the oldest known baleen whale, and was probably a suction feeder of small prey on the seafloor.
