"As a kid." says Malcolm McKenna 

 (page 56), "I read Roy Chapman An- 

 drews's books and promptly caught 'Cen- 

 tral Asia fever." I haven't recovered yet 

 and don't plan to." The American Mu- 

 seum's Gobi expeditions give him and his 

 wife, Priscilla, the opportunity each sum- 

 mer to build on the work started by An- 

 drews in the 1920s. Frick Curator of 

 Vertebrate Paleontology at the American 

 Museum and a professor of geology at 

 Columbia University, McKenna is also 

 the president of the scientific senate of the 

 Museum. His current research focuses on 

 the family tree of living and extinct mam- 

 mals. McKenna started to collect fossils 

 in North America as a teen-ager, and 



S. David Webb (page 50) first started 

 paying attention to fossils when, as a 

 young cowboy, he observed fossil out- 

 crops on the range in Nevada. Later, at 

 Cornell University and at the University 

 of California at Berkeley, he became in- 

 terested in evolutionary questions. A cu- 

 rator of fossil vertebrates at the Florida 

 Museum of Natural History and a profes- 

 sor of zoology at the University of 

 Florida, Webb notes that "it took me a 

 while to realize that in Florida the best 

 fossil sites are underwater." Since 1965, 

 he has been diving for fossils. Webb's re- 

 search includes the Great American Inter- 

 change, late Pleistocene extinctions, and 

 the origin of deer and other ruminants. He 

 and his wife raise horses on their farm 

 near Gainesville, Florida. 







some forty-five years later, he has done 

 fieldwork worldwide. His future plans in- 

 clude studying mammal faunas of the 

 Arctic, South America, and Mongolia; 

 "Wyoming, Colorado, and Montana also 

 beckon." 



A native of Nebraska, Larry Martin 



(page 59) has spent most of his life on the 

 (3reat Plains. Now a curator of vertebrate 

 paleontology at the Kansas Museum of 

 Natural History and a professor in the 

 Department of Systematics and Ecology 

 at the University of Kansas, he has done 

 extensive fieldwork in those states, as 

 well as in South Dakota, Wyoming, Col- 

 orado, and Montana. Maitin first saw 

 devil's corkscrews in 1964 when, during 

 an investigation of a fossil mammal find 

 near Harrison, Nebraska, a local land- 

 owner, Lorena Ellicott, showed him the 

 corkscrews in the neighborhood. Martin 

 is the author, with Bruce Rothschild, of 

 the recent book Paleopathology: Disease 

 in the Fossil 

 Record (Boca 

 Raton: CRC 

 Press, 1993). 

 His future 

 plans include 

 analyzing the 

 skeleton of 

 Archaeop- 

 teryx and con- 

 tinuing work 

 on the fossil 

 burrow com- 

 munities of 

 early Miocene
