▪ Abstract The latitudinal gradient of decreasing richness from tropical to extratropical areas
is ecology's longest recognized pattern. Nonetheless, notable exceptions to the general …

Marine organisms have occupied hard substrates since the Archaean. Shells, rocks, wood
and sedimentary hardgrounds offer relatively stable habitats compared to unconsolidated …

Sedimentology and stratigraphy are neighbors yet distinctly separate entities within the earth
sciences. Sedimentology searches for the common traits of sedimentary rocks regardless of …

The Paleobiology Database now includes enough data on fossil collections to produce
useful time series of geographical and environmental variables in addition to a robust global …

Whether the fossil record should be read at face value or whether it presents a distorted view
of the history of life is an argument seemingly as old as many fossils themselves. In the late …

Shell fragments are important components of many Recent and fossil marine benthic
ecosystems and can provide crucial information on past and present environmental …

Patterns of origination, extinction and standing diversity through time have been inferred
from tallies of taxa preserved in the fossil record. This approach assumes that sampling of …

Many features of global diversity compilations have proven robust to continued sampling
and taxonomic revision. Inherent biases in the stratigraphic record may nevertheless …

The fossil record is the primary source of data used to study predator-prey interactions in
deep time and to evaluate key questions regarding the evolutionary and ecological …

We evaluate experimentally the effect of carbonate saturation state at the sediment‐water
interface (SWI) on survivorship of various size classes of the juvenile bivalve Mercenaria …
