The GSSP for the base of the Quaternary is at the Monte San Nicola section, Sicily. 2.58 million years ago a sapropel formed due to ocean anoxia and left a handy marker for the golden spike. ⚒️🌍

Two women next to a cleaned section on a weathered slope made of white-ish marine sediments. One women holds a (cardboard) golden spike just above a distinctive dark band 20-30 cm think.
A landscape shot of weathered soft white-beige sediments forming one slope of a valley. The sediments have distinct banding that can be traced right along the outcrop. The other slope is vegetated and 6 people are climbing up it toward the photographer.
