Rather, we focus on a few specific case studies that address this question. Our goal is to address the question, How can paleontology help me with sedimentary modeling? We do not intend to present a complete litany of paleontology's contributions or potential contributions to sedimentary modeling. Our purpose here is to illustrate some potential uses of paleontologic data in solving problems associated with sedimentary modeling, paleoenvironmental interpretations, and stratigraphy, both genetic and sequence. Palaeontology without sedimentology is unsupportable. Sedimentology without palaeontology is lifeless and timeless.

In addition, biotic event horizons (epiboles) can be used as indicators of temporal equivalency across complex depositional facies mosaics and thus serve as important markers for regional correlation.Īn Acrobat PDF file containing the complete paper is available (800 kB). Thus, for example, trace-fossil distribution can be used with care as a tool to help discern transgressive-regressive events. Dependent paleontologic data result from biotic responses to externally mediated physical parameters (e.g., sea level, climate, sediment accumulation rate). Tremendous advances in temporal acuity have resulted from our ability to analyze standard biostratigraphic data bases through the different methodologies of quantitative biostratigraphy.
Independent paleontologic data are taxonomy based and include standard paleontologic techniques, such as biostratigraphy. The relationship of paleontology to sedimentologic and stratigraphic modeling can be viewed as dependent, independent, or some combination of the two. 177-184ĭependent and independent data in paleontology: Tools for the sedimentary modelerĬhristopher G. Kansas Geological Survey, Bulletin 233, p. 233-Maples and West-Dependent and independent data in paleontology: Tools for the sedimentary modeler The text contains many illustrations, which provide compilations of standard classifications, hydrodynamic principles and processes of sedimentation recast in what aims to be an easily understandable format.KGS-Bull. The basic tools for interpreting sedimentary structures are presented using a process approach to physical sedimentology, and reveal stratigraphic relationships not normally found in other texts.
It covers important processes that form sedimentary rocks, explains the interpretation of rock sequences from outcrop scale to regional stratigraphic packages, and synthesizes rock and sedimentary structure classification schemes.
