323 Neogene paleontology in the northern Dominican Republic: Field surveys, lithology, environment, and age

Neogene paleontology in the northern Dominican Republic: Field surveys, lithology, environment, and age - BAP #323 This is the first in a series of papers on the Neogene fossiliferous sediments exposed along the south flank of the Cibao Vally west of the city of Santiago, Dominican Republic. Part One provides field data and stratigraphic and environmental conclusions as a framework for subsequent, detailed faunal and floral studies. Later refinement and alteration in the conclusions is to be expected. Field work carried out in 1978, 1979 and 1980 concentrated on the Río Gurabo and Río Cana sections while other rivers as far east as the Río Yaque del Norte were studied in less detail. The work has provided a number of parallel transects through sediments ranging in age from Miocene to middle Pliocene, giving an insight into the development of the south flank of the Cibao trough. The 887 samples collected in the field have been sorted and distributed for macrofossil and microfossil ana
