Mapping Ancient Africa: Video of seminar 19

July 26, 2024
WDG

On the 25 July 2024 the 19th Mapping Ancient Africa (MAA) seminar, entitled Climate frameworks for the Middle Stone Age and Later Stone Age in Northwest Africa, was delivered by Solène Boisard (University Montreal). In the seminar Solène presented two lines of evidence for past climate change in north-western Africa over the last c. 70,000 years. One from mechanistic climate models (via the PastClim package, for more details see: Leonardi et al. 2023) and one from reconstructions based on archaeological evidence. She found good agreement between the two approaches and linked climatic changes to the transition from Middle Stone Age to Late Stone Age technologies.

PhD Thesis: Morphometrics of modern and fossil Poaceae pollen from South America

December 19, 2023
WDG

On November 17, 2023, Caixia Wei (魏彩霞) accomplished a pivotal milestone by successfully defending her thesis titled “Morphometrics of Modern and Fossil Poaceae Pollen from South America” at the distinguished Agnietenkapel (University of Amsterdam). During the defense ceremony, Caixia showcased her professional knowledge and expertise in the field of paleoecology in a relaxed and cheerful manner. The committee members, promoters (Carina Hoorn, William Gosling, Phillip Jardine), and attendees (~50 people) responded with frequent smiles, laughter, and numerous rounds of applause! After the defense, a delightful reception and dinner were held, where Caixia was showered with an abundance of hugs, kisses, heartfelt wishes, and thoughtful gifts. These wonderful memories will support Caixia on her journey ahead…

For a glimpse into the event, you can watch Caixia’s insightful 10-minute project presentation here:

The technofossil record of humans

Can you spot the technofossil?

Hayley Keen on:

Zalasiewicz, J., Williams, M., Waters, C.N., Barnosky, A.D. & Haff, P. (2014) The technofossil record of humans. The Anthropocene Review, 1, 34-43.

An interesting research article introducing a stratigraphy (technostratigraphy) for and within the Anthropocene, stratigraphic markers are defined as “fossils” left behind by humans (technofossils); for example Iron Age tools from around 1000 BC. The article is driven by the need to:

characterise the deposits, and
date and correlate strata,

of (and within) the Anthropocene in a similar manner to other periods of geological time. By using technofossils from the different stages of homonid technological development Zalasiewicz et al. argue that a chronology can be developed and applied to the Anthropocene concept. Furthermore, Zalasiewicz et al. provide examples of how technofossils, such as pottery and mobile phones, could be used to produce a high resolution (sub-centennial) dating and correlation of strata; so far an unreachable target for other periods of geological time. The paper provides a thought provoking insight the definition of strata throughout geological time, and a novel technique into how this could be done in the Anthropocene.
