"This report lists the placement of 2454 osteological specimens in 17 museums and collections in the U.S., Canada, U.K., Japan, France, and the Netherlands. U.S. Government scientific observers onboard commercial tuna purse seiners in the eastern tropical Pacific (Gerrodette 2009) collected 2454 heads or whole carcasses of dolphins killed in the fishing operation between 1966 and 1992. The specimens were prepared at the Southwest Fisheries Science Center (SWFSC) or the National Museum of Natural History and dispersed to museums in several countries. The osteological specimens (Appendix) consist of skulls or complete skeletons. Associated life-history data (reproductive condition) and other tissues (gonads and teeth) are archived at the SWFSC, as are the original field data forms (containing blood stains from the specimens). Photographs and external measurements are available for some. The museum material includes a number of series of specimens taken together in single schools"--Summary.
