the examination of the ages of rock strata by using fossils
biostratigraphy in American English
(ˌbaioustrəˈtɪɡrəfi)
noun
a branch of geology dealing with the differentiation of sedimentary rock units on the basis of the fossils they contain
Derived forms
biostratigraphic (ˌbaiouˌstrætɪˈɡræfɪk)
adjective
Word origin
[bio- + stratigraphy]bio- is a combining form meaning “life” occurring in loanwords from Greek (biography). On this model, bio- is used in the formation of compound words (bioluminescence). Other words that use the affix bio- include: bioenergetics, biogeochemistry, bionic, biosocial, biotechnology
