Abstract Trace fossils record foraging behaviors, the search for resources in patchy environments, of animals rock record. Quantification strength, density, and nature behaviors enables investigation how these may have changed through time. Here, we present a novel approach to explore such patterns using spatial point process analyses quantify scale strength ichnofossil distributions on horizon...

Vertical changes in distribution, abundance, and ichnodiversity of ichnocoenoses in alluvial deposits of the Willwood Formation suggest significantly drier moisture regimes in the Bighorn Basin, Wyoming, during the Paleocene–Eocene Thermal Maximum (PETM), a transient period of global warming. The Willwood Formation at Polecat Bench contains an abundant assemblage of ichnofossils, including vari...

—Vertebrate tracks are a unique, abundant source of fossil data that supplements the skeletal record in many ways. However, the utility of ichnofossil data depends on how specifically the authors of tracks can be identified. Despite this fact, there is little consensus about how to identify potential trackmakers, and existing methods differ in their bases, assumptions, and corresponding implica...

studied sedimentary succession, situated in kerman region between seh konj and kuh-e-shishto, is divided into three lower, middle and upper units of flysch deposits and one conglomerate unit. this succession consists of sandstone, alternation of sandstone and shale, green marls with sandy marl intercalations and conglomerate. in vicinity of chaahar tagari village, middle and upper parts of ment...

—The potential of the ichnofossil record for exploring the evolution of behavior has never been fully realized. Some of this is due to the nature of the trace fossil record itself. Equally responsible is the separation of ichnology from the relevant areas of modern behavioral biology. The two disciplines have virtually no concepts, methods, or literature in common. The study of animal behavior ...

The Enugu Formation is a member of the Nkporo Group, and forms part of the basal stratigraphic unit of the Anambra Basin in south-eastern Nigeria. The Enugu Formation has been the subject of many studies concerning stratigraphy [1], depositional environments [2; Onuigbo et al. [3], organic geochemistry [4-6], paleoecology [7], palynology [7-9] and ichnology [10]. Nwajide & Reijers [2] were the ...
