💁🏻♀️ TIL: 🐋🦴 Chinese scientists piloting the submersible Fendouzhe in the southeast #IndianOcean found fossil sites spanning 1,200 km at depths up to 7,000 m.
The #bones belong mostly to beaked #whales, with the oldest dating back 5.3 million years. Living #jellyfish, brittle stars, and bone-boring #worms still call these ancient carcasses home, allowing whale fall to serve as a #deepsea #ecosystem.

Section 7: Polar Collapses and Thermal InertiaIn the Pliocene, the Greenland ice sheet was largely absent, the West Antarctic ice sheet collapsed, and sea levels rose 15 to 25 meters, carving ancient shorelines like the Orangeburg Scarp 100 kilometers inland. Modern sea levels have not yet risen 20 meters solely due to thermal inertia. While the atmosphere reacts to carbon loading in decades, massive continental ice sheets possess immense thermal mass and take centuries to melt.

Section 6: The Faint Young Sun and Pliocene AnalogsAtmospheric physics dictates that 3.5 to 4 billion years ago, the sun was 30% dimmer, which should have frozen the planet into a solid snowball. Yet, pillow basalts prove liquid oceans existed due to a dense greenhouse gas blanket. This demonstrates that carbon dioxide is the planet's primary thermostat. During the #Pliocene epoch, CO2 levels matched modern values, keeping global temp 2.5 to 4 degrees C hotter.

RE: https://mastodon.social/@sflorg/116003437911970681
This interesting #study is based on ancient lake #sediment #analyses from the #Bogotá #Basin. It proves that the existing #climatemodels about the #Pliocene were underestimated regardung tropical regions. This allows prognoses, according to which also the global warming of today may bring more heat in some #tropicalzones than expected.

Se trata de un útil de la industria lítica Lomekwiense (3,3 MdA), elaborada potencialmente por el Kenyanthropus platyops. Producidos golpeando piedras grandes con rocas densas, y pesadas, que habían obtenido hasta a 100 metros de distancia. Precedió los útiles más antiguos del Olduvayense (2,6 MdA) del Homo habilis, siendo un ejemplo de que la elaboración de útiles no se restringía al género Homo. 📷Museos Nacionales de Kenia-Proyecto Arqueológico Turkana Occidental #plioceno #pliocene

Stupendemys geographica es la tortuga de agua dulce más grande que ha existido, con un caparazón que supera los 2 metros de longitud y la tonelada de peso. Vivió desde el Mioceno medio al comienzo del Plioceno (9-7,2 MdA) sin competición, manteniendo una dieta omnívora que incluía animales duros, como moluscos y pequeños cocodrilos. 📷Ryan Somma #mioceno #miocene #plioceno #pliocene

El oso gigante de cara corta (Arctodus simus) era un omnívoro norteamericano que podía alcanzar excepcionalmente los 4,3 metros de altura en bidepedestación. Su dieta era mayormente herbívora, pero ocasionalmente podía alimentarse de carne, posiblemente carroña.📷Dantheman9758 #Plioceno #Holoceno #Pliocene #Holocene

3 million years ago, greenhouse gas was lower (at 360ppm). Temperatures were warmer, and sea levels were 20 meters higher.
Professor Gavin Foster: “The reason we don’t see #Pliocene-like temperatures and sea-levels yet today is because it takes a while for Earth’s @climate to fully equilibrate (catch up) to higher CO2 levels and, because of human emissions, CO2 levels are still climbing.”

Desde el Mioceno tardío (~11 MdA) hasta el Plioceno temprano (~5 MdA), existió un salmón dientes de sable (Oncorhynchus rastrosus) de hasta 200 kg y 2,4 m de largo. Sus característicos colmillos, que sobresalían lateralmente, los tenía únicamente cuando pasaba a vivir en agua dulce para reproducirse.📷 Lucas Lima #fish #peces #mioceno #miocene #plioceno #pliocene

The right 3rd metatarsal (middle foot bone) from a mastodon, from the #Pliocene or #Pleistocene near Beaumont, CA. It most likely comes from either Mammut pacificus or M. cosoensis. @westernsciencecenter collection. #FossilFriday #paleontology #fossil #museum #mastodon

My art in 2023 (12/12)
December: The Zanclean Flood. 6 million years ago, the movement of the continents cut the Mediterranean off from the oceans. Since more water evaporates from the Mediterranean than it receives from rivers, this resulted in the sea drying up and becoming an incredibly deep, dry, salty lowland. Until 5.3 million years ago, when the Strait of Gibraltar formed and the entire sea was refilled in a massive flood.

A day after an earthquake caused a landslide that allowed the ocean to start flooding into the great dry abyss to the east,the water's power violently widens the gap and now a thousand Amazons flood into what will soon be the Mediterranean Sea again. The local animals have come to a large rock that will one day be named Gibraltar for safety and a view. Except the #Pelagornis, they're more interested in the fish falling down.

I looked up what life was like the last time the Earth had this much CO2 in the atmosphere. Oh boy, are you going to love what I found out.

After Blanchetown I finally made it to Morgan. I investigated an old abandoned quarry I was told had fossils in it. I found this bank of pure oyster shells. This is the classic North West Bend Formation, these oysters grew in the same Pliocene estuary as those Fellasters I didn't find.

And here it is. Sands that were laid down in the Pliocene as the sea retreated from the Murray Valley. Sadly I could not find any fossils here. #pliocene #fossils #fieldgeology Oh well, many miles to go I must press on.

3-Million-Year-Old #Fossils Support #Zealandian Origin for Smallest Living #Penguins https://www.sci.news/paleontology/eudyptula-wilsonae-12039.html
Pliocene fossils support a #NewZealand origin for the smallest extant penguins https://www.cambridge.org/core/journals/journal-of-paleontology/article/pliocene-fossils-support-a-new-zealand-origin-for-the-smallest-extant-penguins/A722D072F8EE3B5FC194A33EF7DBC47F
"The newly-described species is an extinct member of the little #penguin lineage and is the smallest extinct crown penguin yet known. Named Eudyptula wilsonae, or the Wilson’s little penguin, it lived during the Late #Pliocene between 3.4 and 3 million years ago."
