The general acceptance of plate tectonics in the 1960s was the culmination of passionate debates among Earth scientists about Wegener’s continental drift hypothesis over a century ago, and which led to a mobilistic theory for the dynamic evolution of the Earth’s surface. Plate tectonics was originally developed only for the ‘young’ Earth (Cretaceous to Recent), but a key paper by Wilson in 1966 on the existence of a proto- Atlantic Ocean paved the way for efforts to untangle the past location of continents in pre-Mesozoic times. Palaeographic maps set the context for many aspects of Earth history, including biogeography, palaeoclimates, and the tectonic evolution of our home planet. The construction of such maps is best achieved through the integration of data from many sources, such as hotspots (since the Cretaceous), palaeomagnetism (including ocean-floor magnetic anomalies since the Jurassic), and the analysis of faunal distributions and biogeography (notably the identification of faunal and floral provinces), in addition to the character of the rocks themselves. Recently-developed techniques, which pair palaeomagnetism and deep Earth structure – such as the location of subducted slabs and the source regions of mantle plumes from seismic tomography – provide new means of determining the pre-Cretaceous palaeolongitude of continents. These developments have unlocked a new way forward in developing detailed Earth geographies in deep time and this meeting aims to highlight these new opportunities to untangle Earth’s intricate tectonic history, together with discussions about those challenges and controversies which remain outstanding. Expert speakers have been invited from the fields of tectonics, plate reconstructions, seismic tomography, and biogeography. The conference is related to the 80th birthday (June 2018) of Dr. L. Robin M. Cocks and his pioneering contributions to the linkage of Palaeozoic stratigraphy and faunas to global and regional palaeogeography.
