Happy #Halloween #batweek and #fossilfriday!
2 amazing specimens of Palaeochiropteryx tupaiodon
Messel Pit, Eocene, Darmstadt, Germany

I posted these over on the other app (🕊️) back in 2021 but thought they should to be over here too!

    Monsoon-like climate over Europe during the warm and CO2 high Eocene inferred from a bit of modeling and a few years recoded in a shell of a giant sea snail. 🧪⚒️

Very excited to share our more recent paper published today in @nature.com Communications, where we show based on #clumped #isotope measurements in a giant sea #snail 🐚 that Europe experienced a monsoon-like climate during the #Eocene high-CO2 period.

    (Pinnipeds split from other caniforms 50 million years ago during the Eocene Epoch, but it also means that us calling seals water puppies is scientifically correct!)

From Middle Eocene Habib Rahi Formation, Pakistan, "mother whale" is an early cetacean known from a mother and her fetus whose head-first orientation suggests giving birth on land. Though others have suggested the "fetus" is a digested meal (geez, mood kill)

    Hard to understate how nasty the Paleocene/Eocene thermal maximum actually was. Generally people discuss it in terms of "crocodiles in the arctic" and not "an insanely brutal tropical and inland belt"
          
      Paleoclimatologist Jessica Tierney recently published a global temperature record covering almost the past half-billion years. According to her model, 50 million years ago, inland temperatures approached 122 degrees Fahrenheit.

🐜 Titanomyrma (~49 Ma)
The most recently discovered species is a fossilized winged queen comparable in size to a hummingbird.
🐞 Oryctoantiquus (~45 Ma)
A beetle from the middle Eocene. It is known for being the largest scarab beetle discovered so far.

    the bat fossil record is indeed sad but it suggests that echolocation was already considerably refined as early as the mid-eocene which could imply deeper evolutionary roots
