Bonebeds are remarkable features of the vertebrate fossil record that can embody ancient environmental catastrophes and, thus, reveal some of the most dramatic aspects of past ecosystems. They can also serve as less sensational but equally informative gauges of sedimentary dynamics and biological recycling. Regardless of their particular mode(s) of origin, bonebeds, in their many forms, provide exceptional opportunities to investigate a variety of paleobiological and geological questions. This chapter proposes a system for the categorization and analysis of bonebeds analogous to the genetic classification scheme proposed by Kidwell et al. (1986) for marine macrobenthic concentrations. It explains how vertebrate hardparts accumulate and discusses biogenic concentrations, physical concentrations, fluvial channels, strandlines, bioclasts, obrution concentration, and sediment deposition.

Keywords: bonebeds; fossil record; vertebrate hardparts; biogenic concentrations; physical concentrations; fluvial channels; strandlines; bioclasts; obrution; sediment deposition
