This chapter, which presents and reviews a database of 383 citations that refer to more than 1,000 bonebeds, offers additional insight into how bonebeds formed in the past and what they can tell us about the ancient environments within which they formed. Its goals are to: identify, characterize, and document different types of bonebed; identify historical and scientific biases in the treatment of bonebeds; demonstrate the relative frequency of different types of bonebed in the database; identify and quantify patterns of occurrence for the different types of bonebed; and identify and quantify patterns of association between bonebed type and paleoenvironment. Most bonebeds in the database are easily classified using one or more of the following three measures: element size, taxonomic diversity, and relative taxonomic abundance. In addition, patterns of occurrence are identified in relation to the relative abundance of different types of bonebed, inferred mechanisms of origin, and recurrent associations of bonebed type and paleoenvironment.

Keywords:   bonebeds, paleoenvironment, element size, taxonomic diversity, relative taxonomic abundance, occurrence, database
