The fossils come from a section of the early Oligocene (~29-27 Ma) San Sebastian Fm. in NW Puerto Rico. One of these we dubbed praecursor and is represented by two lower molars. 2/n

The Oligocene Pacific had grey, miserable mornings too: see for yourself with my latest post at where the plotopterid Copepteryx braves shoreline drizzle. See it in high-res and find loads of other palaeo content there, from $1 a month. https://t.co/dgsB1VYsyE

For the oldest European ruminant! Bachitherium thraciensis from Bulgaria & Serbia (ca. 38My, Late Eocene). These fossils explain a tectonical diachronism of the faunal dispersals into Europe at the base of the Oligocene (34My vs 31My).

Janjucetus hunderi is an extinct whale from the Oligocene, 25 million years ago. It lacked a baleen system & instead had sharp teeth for ripping apart prey. At 3.5 metres long, it was about the same size a bottlenose dolphin.

Baleen whales are known for their large size, but in the past some were relatively small. Here's the Oligocene baleen whale Fucaia goedertorum, its skull and mandibles are not much larger than the extant Pacific White-Sided Dolphin
