Redate on the controversial Monte Verde site in Chile to a much younger age of ~8000 to 4000 years old.

"the landscape is different now, with more sites that appear to be older than the Clovis culture...their findings highlight the need for independent verification of old archeological sites.'

H/T Richard F. Ott
“The Chiribiquete are table top mountains located deep in the Colombian Amazon and host many rare endemic species. Helanlin Xiang's work shows that the Chiribiquete Mountains likely upifted before the Early Miocene and could have acted as a long-lived stepping stone, connecting species in the Andes with the Guyana Shield…”

Always great to see a bit of humour in scientific papers! Indeed, pesky animals can really mess up your stratigraphy ...

Facies (Petrology 💎)

In geology, a facies is a body of rock with distinctive characteristics. The characteristics can be any observable attribute of rocks and the changes that may occur in those attributes over a geographic area. A facies encompasses all the characteristics of a rock including its chemical, physical, and biological features that distinguish it from adjacent rock. The term "facies" was i...

Dip-slip fault (Geology ⛰️)

In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust f...

Chronostratigraphy (Geology terminology ⛰️)

Chronostratigraphy is the branch of stratigraphy that studies the ages of rock strata in relation to time. The ultimate aim of chronostratigraphy is to arrange the sequence of deposition and the time of deposition of all rocks within a geological region, and eventually, the entire geologic record of the Earth. The stand...
