“…Commonly, accumulations of mammal remains occur in stratified formations, although mammal sites hosted in laterally discontinuous, non‐stratified to roughly bedded deposits characteristic of traps are not unusual. Moreover, trap mammal sites often contain faunal assemblages that are remarkable because of their quality of preservation and singularity, which is the case for many mammal sites found in former ponds, karstic cavities or other kind of clefts, shafts and fissures (Laury, ; Simms, ; Muñoz‐Durán & Van Valkenburgh, ; Reed, ).…”

“…Attempting to understand the factors that determine species abundance in the fossil record has represented a long-standing chal lenge to paleontology. The biological and ecological characteristics of species that might be expected to be either underrepresented or overrepresented in fossil deposits have in many cases been adequately characterized (Andrews 1990;Behrensmeyer 1991;Simms 1994;Behrensmeyer et al 2005); analysis of differential patterns of faunal preservation in different deposits derived from the same source community has led to more meaning ful reconstruction of specific ecosystems (e.g., Munoz-Duran and Van Valkenburgh 2006); and modeling the formation of fossil assem blages in order to diagnose their fidelity to source communities has also been attempted (Damuth 1982). However, efforts to quantify preservational biases in species abundance between fossil faunas and source communi ties have been almost completely prevented by a lack of any independent data on the ecological composition of prehistoric faunas other than that provided by the fossil record itself.…”

“…Common problems encountered in studying fossil lineages are the heterogeneous quality of localities and the uncertain endpoints of taxon durations. In addition, although taphonomic differences among mammals of different body sizes have long been recognized (39,40), the bias introduced into preservation rates has not been incorporated in analyses in a comprehensive fashion. We embrace these issues and clearly demonstrate, using various analytical approaches, that large mammals have both higher extinction and origination rates and therefore a duration distribution that has a more truncated right tail.…”
