What does that mean for the Anthropocene? (Photo: East Khasi Hills in Megahalaya, India. The state is the namesake of the new geological age. Credit: Sai Avinash via Wikimedia Commons)

If you were suddenly told you were living in a different time period, what would your immediate reaction be? Changes in the calendar – even if it’s just terminology – have proven emotive in the past. In 1752, when England shifted from the Julian to Gregorian calendars, and 11 days were cut from 1752 to catch up, there are suggestions that civil unrest ensued. Once again, the name of the period in ...[Read More]

The heights we go to for science… This photograph shows a member of our team preparing to abseil down a cliff in the Charyn Canyon, in the Ili River basin of southeast Kazakhstan. The Charyn River and its tributaries, a branch of the Ili River north of the Tien Shan Mountains, have cut canyons up to 300 metres deep, carving through rocks of different geologic ages, some as old as 540 million years ...[Read More]

The limestone is rich with foraminifera shells, most of them from the Nummulitidae family. These organisms once lived in a very shallow sea that separated Europe from Iberia in the late Mesozoic and early Cenozoic era. Later the sea basin’s closure led to the formation of the Pyrene ...[Read More]
