Conceptual framework for the analysis and classification of fossil concentrations
TL;DR: In this article, a ternary classification scheme for skeletal concentrations is proposed, based on three end members, representing biologic, sedimentologic, and diagenetic factors in skeletal concentration.

Abstract: Densely fossiliferous deposits are receiving increasing attention for their yield of paleobiologic data and their usefulness in sedimentology and stratigraphy. This trend has created a pressing need for standardized descriptive terminology and a genetic classification based on a coherent conceptual framework. The descriptive procedure outlined here for skeletal concentrations stresses four features -taxonomic composition, bioclastic fabric, geometry, and internal structure-that can be described readily in the field by nonspecialists. The genetic classification scheme is based on three end members, representing biologic, sedimentologic, and diagenetic factors in skeletal concentration. Concentrations created through the simultaneous or sequential action of two or more factors are classified as mixed types. As a conceptual framework for comparative biostratinomic analysis, the broad categories of this ternary classification scheme should facilitate recognition of large-scale temporal and spatial patterns in skeletal accumulation. The usefulness of this approach is suggested by the good agreement between biostratinomic patterns observed in ancient onshore-offshore facies tracts and those predicted across paleobathymetric transects based on modern processes of skeletal concentration.

A new analytical procedure to graphically characterize the taphonomic properties of skeletal carbonates. an example from miocene limestones of new zealand
TL;DR: In this article, a graphical representation of the taphonomy of skeletal carbonates observed at the thin-section scale is proposed, demonstrating their utility in drawing information about the effects of early sea-floor processes on the post-mortem fate of fossil hard parts.
Sedimentology and Palaeoecology of Ernietta-Bearing Ediacaran Deposits in Southern Namibia: Implications for Infaunal Vendobiont Communities
El Hafid Bouougri,Hubertus Porada,Klaus Weber,Joachim Reitner +3 more
- 01 Jan 2011
TL;DR: The Ediacaran was a period of wide soft-bodied biota development in marine siliciclastic environment as discussed by the authors, and the reconstruction of palaeoecology, lifestyle and environment settings of these organisms are among the challenges in characterising the earliest metazoan life on Earth.
Preservation of large titanosaur sauropods in overbank fluvial facies: A case study in the Cretaceous of Argentina
TL;DR: In this article, the first detailed sedimentological and taphonomic analyses of a dinosaur bone quarry from northern Neuquen Basin have been provided, which correspond to a large (18-27m long) sauropod titanosaur collected in the strata of the Late Turoronian-late Coniacian.
Late Quaternary Faunal Changes in Northeastern Patagonia (Argentina) according to a Dynamic Mosaic of Benthic Habitats: Taphonomic and Paleoecological Analyses of Mollusk Assemblages
TL;DR: In this paper, the authors describe and interpret the paleoenvironmental history of the San Matias Gulf (SMG) in northern Patagonia, Argentina, associated to possible biotic and abiotic changes occurred during the late Quaternary.

Classification of Carbonate Rocks According to Depositional Textures
Robert J. Dunham
- 01 Jan 1962
TL;DR: In this paper, three textural features seem especially useful in classifying those carbonate rocks that retain their depositional texture: presence or absence of carbonate mud, which differentiates muddy carbonate from grainstone; abundance of grains, which allows muddy carbonates to be subdivided into mudstone, wackstone, and packstone; and presence of signs of binding during deposition, which characterizes boundstone.

Sedimentological, ecological and temporal patterns of fossil Lagerstätten
TL;DR: A more pragmatic, typological classification of conservation deposits, using a standard questionnaire, reveals ecological replacements, as well as trends related to the evolution of the biosphere, through geological time.

Limestone Response to Stress: Pressure Solution and Dolomitization
TL;DR: In this paper, three styles of pressure solution response are recognized in Paleozoic limestones studied from Arizona, western Maryland, and southeast Kansas, and three forms of limestone pressure solution produce some types of finely crystalline stratigraphic dolomite, provide local sources of magnesium for dolomerization and calcite for porosity-filling cement, and severely distort primary sedimentary structures or create secondary structures.
