Other important research that has been published over the past quadrennium, but cannot be discussed due to space constraints includes the ongoing debate regarding the pre-Pangaean configuration of continents [ Dalziel, 1992], statistically rigorous descriptions of plate motions [ Richardson and Cole, 1991], and efforts to deduce the connections between horizontal plate motions, continental uplift, and paleoclimate [ Molnar et al., 1993].
