When applied to the localities of a set of European Neogene land mammal taxa, spectral ordering relies almost entirely on the most common genera, depends on connectivity more than on length of taxon lists, and is robust to noise from rarer and less connected taxa. The spectral coefficients for localities are highly correlated with known geochronological ages. Although elementary compared with more sophisticated biochronological tools, spectral ordering allows a fast and standardized way to generate biochronological ordering of localities when other information than faunal lists is lacking. Compared with the conventional mammal Neogene (MN) units, spectral ordering of localities appears to lack distinct temporal boundaries in taxon content and render a much lower count of Lazarus events. If, as seems to be the case, biochronology depends mainly on the most common taxa and if evolutionary change is also most clearly reflected in them, then the main evolutionary patterns should be detectable at a modest level of sampling. 04 08 2016 2006 206 214 S0094837300023484 https://www.cambridge.org/core/terms 10.1666/04087.1 https://www.cambridge.org/core/product/identifier/S0094837300023484/type/journal_article https://www.cambridge.org/core/services/aop-cambridge-core/content/view/S0094837300023484 http://www.bioone.org/doi/10.1666/04087.1 Schweizerische Paläontologische, Abhandlungen The Eocene mammal faunas of Mormont, Switzerland 120 1 2000 Hooker 10.1007/978-1-4899-2513-8 Mitteilungen der Bayerischen Staatssammlung von Paläontologie und historische Geologie The MN system: regional or continental? 38 243 1998 Alroy 10.1017/S0094837300010873 10.1666/0094-8373(2000)026<0707:NMFQMP>2.0.CO;2 Actes du Congrès BiochroM '97 567 1997 Azanza Pattern classification 2001 Duda 10.1109/43.159993 10.1666/0094-8373(2004)030<0001:MRAIFA>2.0.CO;2 10.1038/417538a 10.1017/S0094837300012677 10.1144/GSL.SP.1996.101.01.13 10.1127/nos/24/1991/159 10.1007/978-1-4899-2513-8_6 Mein, P. 1989.
