Óscar Ricardo Solís Torres

Postdoctoral Researcher
Department of Archaeology

Main Focus

My research focuses on first settlers in tropical America and the impacts of human arrival and climate change on the demise of large mammals using Zooarchaeology by Mass Spectrometry (ZooMS), stable isotope analyses, radiocarbon dating, and taphonomy (including cutmark analysis, site formation studies) to megafaunal remains from a series of submerged caves and sinkholes (cenotes) of the Yucatan Peninsula.

Curriculum Vitae

Óscar holds a PhD in Mesoamerican Studies from the Universidad Nacional Autónoma de México. His PhD work is one of the first, anywhere in North and Central America, to try and gain direct insights into the environments and ecologies facing the earliest members of our species moving into this part of the world during the Pleistocene. Óscar received an international MPhil in Quaternary and Prehistory from the Universitat Roivirai Virgili, Tarragona, Spain. 

His fieldwork record stands out and includes participation in excavations ranging from major Upper Paleolithic sites in Spain and Germany through to multi-period sites in Mexico. Moreover, he has undertaken research stays and training in zooarchaeology at a world-leading group in Italy. He has participated in underwater explorations in the Yucatan Peninsula, Mexico, and in national and international conferences.
