"KEY POINTS
• Basalts and pebbly to cobbly sandstones have been dredged from the Fairway Ridge, Coral Sea
• Dating of the rocks and interpretation of magnetic anomalies allow mapping of major geological units across North Zealandia
• This work completes offshore reconnaissance geological mapping of the entire 5 million square km Zealandia continent…”

#Sanidine from the Fish Canyon Tuff is essential to understanding the pace of events in the #Cenozoic

High potassium, quickly erupted and cooled, and old enough to have accumulated sufficient 40Ar from radioactive decay. These crystals calibrate neutron flux for 40Ar/39Ar dating. The 28.2 Ma age of the FCT sanidine has been fine-tuned using #Milankovitch cycles of other ash beds in stable sedimentary basins.

Pulga del Cenozoico que quedó atrapada en el ámbar hace 20 millones de años. En su probóscide contiene lo que se cree una cepa ancestral de Yersinia pestis, regurgitada porque forma una masa viscosa en el proventrículo, impidiendo que se alimente de sangre. 📷George Poinar, Jr. #cenozoico #cenozoic

Capitalocene

The debate about our ecological predicament is heating up and, as it turns out, the Marxian critique of political economy is at the center of that debate. Much of the discussion right now concerns …

Ancient marine #animal had inventive past despite being represented by few species https://phys.org/news/2024-07-ancient-marine-animal-species.html

Morphological innovation did not drive diversification in #Mesozoic–#Cenozoic brachiopods https://www.nature.com/articles/s41559-024-02491-9

#Brachiopods were evolving in new directions but this did not become an evolutionary success in terms of the numbers of species... The findings shed light on some core principles of the #evolution of modern #biodiversity.

Ancient marine animal had inventive past despite being represented by few species, new study finds

Brachiopods were evolving in new directions but this did not become an evolutionary success in terms of the numbers of species, researchers at the University of Bristol, the Open University, and the China University of Geosciences have found.
