window [geophys] . (a) A portion of a seismic record free from certain disturbances, i.e., where noise trains are absent. (b) The portion of a data set chosen for consideration, such as for designing operators to be used for autocorrelation or frequency analysis. Syn: gate [geophys].

mesofossil (mes'-o-fos-sil). A term defined by Hughes (1994) as a plant fossil of intermediate size. Ranging between megafossils (e.g., leaves) and spores or pollen, it still requires microscopic study, such as megaspores and small seeds.
