Paleocommunities of the Yorktown Formation (Pliocene) of Virginia
… of local paleocommunities, paleocommunities, and paleocommunity types. Three paleocommunity types which occured under specific paleoenvironmental conditions were defined: rubbly bottom, transitional, and muddy bottom. Within a single locality samples from the same paleocommunity type yielded very …

Community persistence and the pattern of community variability over time: a test using fossil assemblages from four marine transgressions in the Breathitt Formation (Middle Pennsylvanian) of Eastern Kentucky
… fossil assemblages sampled into a variety of paleocommunity types, each associated with a particular lithological facies. Paleocommunity types that were found to occur in more than one of the four marine intervals were resampled at selected localities, with replicate samples taken at each …

Dynamic systems analysis of fossil dinoflagellates from the Atlantic Coastal Plain, USA
… but not the same. Therefore they represent paleocommunity types rather than paleocommunities. Although individual sinofiagellate species recur in similar environmental settings, the paleocommunity types do not appear to repeat. In the past, such associations have been used as depth …

Biovolume and ecoguild analysis of Late Paleozoic Ice Age benthic communities.
… findings emphasize the importance of small-scale paleocommunity analyses for understanding larger scale macroevolutionary trends in the context of the LPIA.

Small mammal faunal stasis in Natural Trap Cave (Pleistocene-Holocene), Bighorn Mountains, Wyoming
Paleocommunity behavior through time is a topic of fierce debate in paleoecology, one with ramifications for the general study of macroevolution. The predominant viewpoint is that communities are ephemeral objects during the Quaternary that easily fall apart, but evidence exists that suggests …

Rise of present-day tetrapods in the paleotropics of Late Triassic equatorial Pangaea: new insights from microvertebrate data
… and lepidosaurs), as well as the vertebrate paleocommunity record of Triassic equatorial Pangaea. My first chapter describes and analyzes an assemblage of gymnophionomorph (stem caecilian) bones from PFV 456 which represent the oldest-known caecilian fossils globally. As the oldest caecilian …

Cenozoic deep-water agglutinated foraminifera in the North Atlantic
… is illustrated by a study of the paleocommunity structure of fossil assemblages in ODP Hole 646B on the Eirik Ridge (Labrador Sea). The synecology of benthic foraminifera in Hole 646B places constraints on the history of Denmark Straits Overflow Water over that site. Below seismic …
