I had to click on his username, only to find out that his last upload is a 'documentary' about an alien city in Antarctica. 🤦

Fresh article in PNAS, by Udara Amarathunga & co.
Using geochemical data and numerical models, we identify oxygenation of the Mediterranean and a 33kyr salinity stratification in the earliest Pliocene, both consistent with the Zanclean Megaflood hypothesis

Small populations of Stone Age people drove dwarf hippos and elephants to extinction on Cyprus
Pig-sized hippos and elephants the size of horses once roamed the lush forests of Cyprus – until humans arrived.

¿Qué fue la ‘tercera España’?
En el conocido como ‘Contubernio de Múnich’ se sentaron las bases para una posterior reconciliación española en base a una idea que se alejaba de las ‘dos Españas’.

Hace 5 millones de años, el Mediterráneo fue un desierto salado. ¿Te lo imaginas? Nos lo cuenta @danigeos.bsky.social de @geo3bcn-csic.bsky.social:
La paradoja mediterránea: un nuevo estudio explica cómo el mar parece haber estado lleno y vacío a la vez
Hace unos cinco millones de años, hubo un tiempo en que el Mediterráneo se secó. Ya no podía retener el agua de los ríos en sus desembocadoras y estos pasaron a formar lagos someros en su centro, trayendo nuevas especies acuáticas desde Europa del este.

Happy that the paper linked to this model is now 'in press' in Science Advances.
First time we run this was 2009. It took us 13 years to understand what's the question it could answer:
The mystery of the extreme sea levels of the Mediterranean Sea during the Lago-Mare period.
