This interdisciplinary meeting brought together specialists from various fields (magnetostratigraphy, palaeoclimatology, cyclostratigraphy, palaeoecology, biostratigraphy, geochronology, archaeology…) in order to provide an updated overview of the Early-Middle Pleistocene transition (~1.2-0.5 Ma), with a special focus on the Jaramillo Subchron (1.07-0.99 Ma). Despite its increasing importance in Quaternary studies as a chronological landmark within the second half of the Early Pleistocene, the information available about this subchron remains still quite fragmented. Consequently, the main goal of the meeting was to share new results and ideas that are relevant to this period of time and promote future studies.

This international meeting took place at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) located in Burgos, Spain, from 25 to 27 September 2013. It involved 34 invited research scientists from eight different countries. The meeting was divided into six main sessions over 2.5 days, each of them including an opening key note lecture of ~45 min focused on an updated overview of a given field, and between two and five standard presentations of ~20 min centered on more specific/punctual research aspects.

In order to encourage scientific exchange and debate, some time was intentionally left for discussion in the programme, not only right after each talk, but also at the end of some sessions. In addition, a final Round Table was organised at the end of the meeting, in order to summarize the main ideas developed during the days before, raise unsolved questions and indicate new avenues worth exploring in the future.
