International meeting on the study of microvertebrates in archaeological sites

Promoted by IPHES, the 3rd Congress of the Microvertebrate Working Group (MVWG), which belongs to the ICAZ, was recently held in virtual mode

With more than 35 papers presented, the broad focus of the congress was on the role of microvertebrate fossils in reconstructing past environments

Interactions between hominids and wildlife, as well as the effects of climate change, were also the focus of much of the discussion

Promoted by members of the IPHES (Catalan Institute of Human Paleoeoclogy and Social Evolution), the 3rd Congress of the Microvertebrate Working Group (MVWG), which belongs to the International Council for Archaeozoology (ICAZ), was recently held in virtual mode. With 60 people registered and more than 35 papers presented, the role of these fossils in studies related to climate change, taphonomy, commensalism, taxonomy, evolution, palaeoenvironmental reconstruction, biostratigraphy, biochronology and new methodologies and techniques (such as the analysis of ancient DNA) was discussed.

The topics addressed covered a geographic range including South America and the Caribbean (Argentina, French Antilles) to Southeast Asia (Thailand and Cambodia) through Europe, the Middle East (Iran) and South Africa.

The Microvertebrate Working Group (MVWG) was created in 2016 by Angel Blanco Lapaz (Senckenberg Centre for Human Evolution) and Sara E. Rhodes (University of Tübingen) in the framework of ICAZ, as a forum for the exchange of data and information related to the study of insectivorous, rodent, bat, reptile and amphibian remains from archaeological contexts. Its main objective is to provide a platform for the exchange of ideas and increase communication among academics, professionals and, in particular, graduate students with research interests related to microvertebrates. To this end, this Working Group organizes a meeting every two years, the first two taking place in Alcalá de Henares (Spain, 2016) and in Ankara (Turkey, 2018). This year meeting was to be held at the IPHES, in Tarragona, but the Covid-19 pandemic forced the event to become virtual. Despite this shift in venue, it received financial support from the AGAUR (Agència de Gestió d’Ajuts Universitaris i de Recerca) (groups 2017-SGR-859 and 2017-SGR-836).

IPHES was chosen to host the meeting due to the fact that the institute includes a large number of research personnel (senior, postdoctoral and predoctoral) dedicated to the study of small mammals, reptiles and amphibians. This international group, under the coordination of doctors Juan Manuel López-García (IPHES) and Hugues-Alexandre Blain (IPHES-URV), virtually organized this third congress of the MVWG from Tarragona.

In the first session (“Human and small vertebrate interactions”), the communications were “Statistics, taphonomy and representativeness: Making the most out of archaeological micromammal assemblages”, by Andrzej Romaniuk (University of Edinburgh, Scotland); “On the dispersal of the Etruscan shrew (Suncus etruscus) across the Mediterranean Basin”, by Ángel Carmelo Domínguez García (Universidad Complutense de Madrid); “Reconstructing the context of the earlier human occupation of Europe. New results from the small mammals of Pirro Nord 13 (Early Pleistocene, Apricena, southern Italy)”, by Claudio Berto (University of Warsaw, Poland); “Zooarchaeology of reptiles in tropical areas: the beginning of a long story?”, by Corentin Bochaton (University of Bordeaux, France); “Palaeobiogeographic analysis of the amphibians and reptiles from the mid-late Holocene transition of El Mirador cave (Atapuerca, Spain) in the North-Iberian post-glacial context”, by Josep Francesc Bisbal-Chinesta (IPHES-URV); and “Human meets Woodmouse: An assemblage of anthropophilous Apodemus in Middle Neolithic wells from the site Les Bagnoles, SE-France”, by Simone Häberle (University of Basel, Switzerland).

Rhodes (University of Tübingen, Germany); “The Howiesons Poort micromammal assemblage at Klipdrift Shelter, South Africa, – local palaeoenvironmental implications”, by Turid Hillestad Nel (University of Bergen, Norway); and “Climatic and environmental transition from latest Pleistocene to earliest Holocene in northeastern Iberia: Balma del Gai (Moià, Barcelona)”, by Sandra Bañuls-Cardona (IPHES-URV).
