Abstract: This paper explores some of the new perspectives resulting from re-examination of the pollen data from my 1978 comprehensive analysis of 100 coprolites from one of the earliest identified prehistoric latrines in North America. Of particular interest are the empirical results of previously unavailable pollen concentration calculations for some of the prehistoric specimens as well as a time-series of 82 modern fecal specimens produced during an experiment yielding data on the rate of elimination of specific pollen grains from the human system. Experimental data of all sorts are needed to extend coprolite analyses and interpretations, particularly from pollen-ingestion studies conducted with more volunteers over long periods of time. Parasitological studies of human coprolites will benefit from experimental data to determine the fate of the constituents of human feces ingested by dogs. The application of specialized techniques at the microscope, such as Intensive Systematic Microscopy ([Dean, G., 1998. Finding a needle in a palynological haystack. In: Bryant, V.M., Wrenn, J.H. (Eds.), New Developments in Palynomorph Sampling, Extraction, and Analysis. Am. Assoc. of Stratigraphic Palynologists Foundation., Contribs Series No. 33, pp. 53–59]), to locate and quantify rare pollen types needs to be explored. Easy and useful ways to express the abundance of macroremains in a coprolite are also needed. [Copyright &y& Elsevier]
