The 9th Mapping Ancient Africa seminar, and first of 2023, took place on Thursday 19 January. The seminar was delivered by Celine Vidal (University of Cambridge) and showcased recent work on the dating of volcanic deposits to constrain the age of hominin fossils in eastern Africa.

Details of this seminar can be found here. You can find more Mapping Ancient Africa seminar videos on the “Ecology of the Past” YouTube channel.

Sediment sampling on the Andean flank, Ecuador

October 10, 2012

One of the key goals of the fieldtrip to Ecuador (August-September) was to sample organic and volcanic (tephra) layers from sedimentary exposures with the aim of obtaining new information about past envrionmental change in the region. Our Ecuadorian collaborator, Dr Patricia Mothes (Instituto Geofisico), had identified four of sites she thought might be useful too us: El Fatima Dique, Mera “2” Dique, El Rosol and Vinillos. 

Fatima section

At the Fatima site, near Puyo, a thin organic bed was sampled sandwiched between volcanic ash deposits. Wood macrofossils from this deposit have been dated to the last glacial period.

For further descriptions of what we found and field photos read on…
