      We are very excited to announce the arrival of our new VHX7000 Keyence microscope!

This incredible piece of imaging technology allows for analysis at x20-x2500 magnification, as well as for the creation of publication quality images. Through the use of advanced lighting and image stitching on both the x, y and z axis, the Keyence can form 3D images, create optical SEM (shadow enchanced mode), and coloured mapped images for both transmitted and reflected light. The program can also be taught to auto-count and measure objects. We’re still checking out everything this microscope can allow us to achieve, but so far the results are pretty spectacular.

Dr Ramya Bala Prabhakaran gave a great talk on Monday as part of the ongoing seminar and working group ‘New Avenues in Archaeological and Anthropological Science, co-organised by the Penn Paleoecology Lab and the Center for the Analysis of Archaeological Materials (CAAM). Dr Prabhakaran’s talk was titled “Stable Isotopes and Molecular Biomarks as Proxies for Paleoenvironments” and sought to explore how these could be used in a variety of contetxs to explore past human land use and interaction with the environment.

Dr Bates has a new paper out today in Archaeological Research in Asia:

Kitchen gardens, wild forage and tree fruits: A hypothesis on the role of the Zaid season in the Indus Civilisation (c.3200-1300 BCE)

“The nature of agriculture in the Indus Civilisation of South Asia (c.3200-1300 BCE) remains a topic of intense debate. Traditional models of Indus agriculture have been built on the assumption that it was divided into two cropping seasons: rabi (centred on the winter Western Disturbance) and kharif (focused on exploiting the Indian Summer Monsoon). This paper endeavours to unpack this assumption by looking to modern agricultural strategies. Through this approach the nuanced possibilities open to ancient farmers can be explored and a third cropping season is introduced, the hot dry summer season, also called zaid. […] The paper reviews the archaeobotanical data and hypothesises that Indus farmers had the potential to exploit the zaid cropping season, and that Indus agricultural strategies may, as a result have been even more complex than currently modelled. […]The zaid hypothesis has implications for how Indus agriculture fits into wider debates surrounding of adaptation, intensification, sustainability and resilience in the face of social, economic and environmental change.”

Prof. Morrison gave an excellent talk this evening on the LandCover6K project and the role of archaeology to explore past land use, land cover and climate modeling. The talk was held at the Penn Museum as part of their Great Lecture Series, and was packed! Prof. Morrison explored how the LandCover6k, an international scientific working group, is leading the unprecedented effort to integrate the large, scattered record of archaeological and historical data on past land use and land cover. She asked the question: how can we connect archaeological insights from around the world? In doing so the talk aims to show how as archaeologists we can better understand the long-term record of human impact on the earth and to contribute directly to the improvement of climate models.

Pollen analysis has started in the lab!

Kacey Grauer from Northwestern University is visiting to learn pollen extraction and identification methodologies with Prof. Morrison here at the Penn Paleoecology Lab. Kacey is a doctoral candidate, with a specialism in paleoethnobotany. She uses microbotanical analysis to study human-environment relationships, and has research interests in political ecology, ontologies, materiality, landscape, and archaeology. Kacey has been conducting archaeological research in Belize for 9 years, the last 5 of which have been spent on the Aventura Archaeology Project. Kacey’s research and publications can be found here: http://northwestern.academia.edu/KaceyGrauer

Delighted to have Dr Amanda Logan from Northwestern University visit the lab. Dr Logan was the speaker at the Penn Anthropology ‘Food’ Colloqium today, with an incredible talk entitled “The Scarcity Slot: Excavating Histories of African Food Security”. Dr Logan is an archaeobotanist focusing on how we can connect the past to the present, and thinks about how we can reframe the kinds of questions we ask and empirically bridge the modern/premodern divide. Her current research is building an archaeology of food security that traces how, where, and when chronic hunger emerged across the African continent.

Dr Jennifer Bates presented a paper at the Annual Conference on South Asia, hosted by UW-Madison today, entitled Indus Foodways: exploring the implications of new theoretical perspectives beyond ‘diet’ and ‘subistence’. It was part of a larger sessions on ‘The Foundations of South Asian Cuisine: Indus foodways in urban and rural settlements’ roganised by Dr Richard Meadow. More information on the session can be found here: https://register.southasiaconference.wisc.edu/Schedule

Exciting times! UPenn undergraduates can now chose Environmental Anthropology as their major!

If you are a UPenn undergrad and want some hands on archaeobotany or isotope lab experience, or a project to work on, visit the lab for a chat, we’re always happy to welcome new faces.

Dr Ramya Bala Prabhakaren has been over at Drexel University’s Department of Biodiversity, Earth & Environmental Science in Prof. David Velinksy’s lab for the last couple of weeks prepping sediment samples from Hampi area, Kadebakele for carbon and nitrogen isotope analysis.

The samples look great and everyone in the lab is super excited for the results! Watch this space for more updates!

Dr Bates has a new paper out today in the Journal of Open Archaeology Data:

The Published Archaeobotanical Data from the Indus Civilisation, South Asia, c.3200–1500BC

“The collection of this dataset of published archaeobotanical data from the Indus Civilisation (c.3200–1500BC) was carried out by the author as part of her doctoral work, and has continued up to October 2017. The dataset represents a systematic collation of all primary published macrobotanical data, regardless of their designation as ‘crop’, ‘fully domesticated’ or ‘wild/weedy’ species. The dataset comprises 63 sites and 339 ‘taxa’ (including less confidently identified elements such as ‘charred seed’). Data is presented as presence/absence due to different sampling, quantification and data presentation practices.”

First lab meeting today! Ramya presented her project at Mudumalai, looking into historic land-use and land cover changes, and the role of fire in particular. A great first lab meeting for Penn Paleoecology lab.

 

08/01/2019

Today we were delighted to host Prof. Marie-Claude Boileau and her interns from Penn Museum’s CAAM Lab. Jennifer and Ramya discussed the aims of the lab and their projects, as well as the practical aspects of sediment isotopic analysis, radiocarbon dating, and phytolith analysis. For more info on the CAAM Lab’s check out @CAAMatPenn and CAAM.
