[email protected] ABSTRACT The Paleogene location of the Chortis block relative to southern Mexico is presently a hotly debated topic, with various types and qualities of data brought to bear on the topic. There are currently three competing Cenozoic reconstructions: (i) the traditional model that places the Chortis block adjacent to southern Mexico, (ii) the near in situ model in which the Chortis block is located relatively near to its present position, and (iii) the Pacifi c model that places the Chortis block WSW of its present location.
