Found some 33-ish million year old (Oligocene) snail fossils yesterday, and had a lovely beach day.

Something too rarely posted on #FossilFriday: #Pollen
E.g. from the late #Oligocene to early #Miocene of #Thailand
Fresh #OpenAccess paper coauthored by my former colleagues.
Malaikanok & al. https://doi.org/10.1093/botlinnean/boac075
Pic1: paratropical #Eotrigonobalanus (extinct)
Pic2: cycle-cup oak (#Quercus sect. #Cyclobalanopsis; today tropical-subtropical)
Pic3: holm oak (sect. Ilex, same subgenus; tropical to cold-temperate)
Pic4: white oak (sect. Quercus, other subgenus, today extratropical in Eurasia)

The #Oligocene was a time of changing #climate, expanding #grasslands, and giant #mammals. This #FossilFriday, though, let's meet a smaller but much more abundant #mammal that also occupied those early #prairies. #Hypertragulids (like this one the #CUBoulder #Museum of #NaturalHistory) looked a bit like #deer despite being only distant relatives but were the size of #rabbits. #Fossils of this species have been found from the #GreatPlains to #Oregon's #JohnDayFossilBeds to Southern #California.

First (belated) #fossilfriday on Mastodon is: Palaeomaston! This molar is from a cow-sized proboscidean that stomped through the forests of the Fayum Depression of Egypt 30 million years ago. It’s lower tusks formed a scoop and its upper tusks curved around the scoop. #paleontology #elephants #fossils #science #ancient #oligocene #fayum
