Although the Pull of the Recent is sometimes used as a blanket term for all factors that might affect sampling in the fossil record in younger relative to older rocks [e.g., (33)], here we retain Raup's original definition (3).

Such an operational protocol constitutes a conservative test, in that it will maximize the Pull of the Recent: subgenera tend to have fewer species and are more limited geographically than full genera and are, therefore, less likely to be recorded in a given time interval than the more inclusive genera to which they belong.

As predicted by experimental work in the laboratory and the field (16, 34), shell mineralogy was less important than the organic content of shell microstructures: 25% of the missing taxa but only 16% of the taxa recorded in the Pliocene or Pleistocene have shells containing high-organic microstructures such as nacre. The latter difference, although in the expected direction, is at P = 0.08 (resampling with replacement, 1000 iterations).

The increased scrutiny of this time interval over the past two decades has yielded only a few descriptions of new bivalve faunas or taxa: only 108 species (6%) were described in or after 1980. Thus, the high recovery rates and the mild "Pull of the Tertiary" are not attributable to extensive new work on Maastrichtian bivalves.

These analyses were prompted by discussions with the Paleobiology Database group, of which D.J. and K.R. are members. We thank the late J. J. Sepkoski Jr. for encouragement and access to his then-unpublished database, S. M. Kidwell for information on mineralogy and microstructure, and L. C. Anderson, A. G. Beu, E. V. Coan, T. A. Darragh, H. H. Dijkstra, S. H. Kidwell, M. A. Kosnik, K. Lamprell, J. Martinell, P. Middelfart, G. Paulay, J. A. Schneider, J. D. Taylor, J. Todd, T. R. Waller, P. J. Wagner, and A. Warén for taxonomic assistance and advice. We also thank M. Foote, E. M. Harper, and S. M. Kidwell for reviews. Supported by the National Science Foundation; D.J. is an Honorary Research Fellow of the Natural History Museum, London.
