Did Humans Cause the Late Pleistocene-Early Holocene Mammalian Extinctions in South America in a Co 100% of megamam mal species and about 80% of large mammal species became extinct. In this paper, we consider as “megamammals” those with body mass over 1,000 kg, and “large mammals” those over 44 kg (Tables 7.1 and 7.2). With the exception of a few smaller mammals, no other animals or plants disapp

The Elusive Evidence: The Archeological Record of the South American Extinct Megafauna,l in general compilations dealing with Pleistocene extinctions (cf. Martin and Wright, 1967; Klein and Martin, 1984; Barnosky et al., 2004; Steadman et al., 2005; Koch and Barnosky, 2006). The apparent lack of interest is surprising, considering that South America, according to Martin and Steadman (

A chapter on endemic land-mammal extinctions on the islands comprising the West Indies may therefore seem out of place, because (1) few of the species that once lived on the islands would have qualified as megafaunal, even under a generous definition of that term

Afterword, and Thoughts About the Future Literature,, but in the end it is not possible for me as editor to identify a clear majority opinion (and hence solve the puzzle of extinction). Borrero (Chapter 8) sees little useful evidence in South America that human foragers had an impact on megafaunal populations; yet, referring to much of the same and o

Wolfgang W. Osterhage,Christian Gritzner Pampas alone were populated by 38 extinct herbivore genera in excess of 100 kg, 20 of which were megaherbivores, a fauna that has no living analog on the planet (Fariña, 1996; Prevosti and Vizcaíno, 2006). This situation alone must make us acknowledge South America to be an exceptional case, worthy of an intensive and detailed study.
