Trilobites inhabited all environments of Paleozoic seas, ranging from estuaries to continental slopes, and were globally distributed. Although their functional morphology and phylogenetic relations are established by well-preserved body fossils, the ...

Stratigraphic and sedimentological aspects of ichnofabric analysis
Trace fossils are one of the paleontological groups that could be used for solving complex geological problems. Trace fossils represent the sedimentological structures, produced by living organisms in the mass of sediment.

The swimming trace Undichna from the latest Devonian Hangenberg Sandstone equivalent of Morocco
Trace fossils occur in several strata of the Devonian and Carboniferous of the eastern Anti-Atlas, but they are still poorly documented. Here, we describe a fossil swimming trace from strata overlying the Hangenberg Black Shale (correlation largely based

Trilobite expansion into estuarine environments during the Ordovician radiation [PDF]
Trilobites have traditionally been considered fully marine. Through the integration of ichnological, palaeobiological and sedimentological datasets within a sequence-stratigraphic and stratiÂgraphic palaeobiology framework, we challenge this assumption.

The uppermost part of the Upper Bathonian Sponge Limestone member, Patcham Formation, of the Jhura Dome of Kachchh Mainland is a thickening- and shallowing-upward succession topped by medium- to thick-bedded hummocky cross-stratified grainstones ...

There are different criteria that are usually analysed independently before identifying a new trace fossil, such as morphological regularity, completeness, dispersion, recurrence and complexity, surface morphology, and context.

KNM-ER 2598 is one of the oldest known Homo erectus fossils but there are doubts about its age. Here, Hammond et al. trace the original location of the specimen, confirming an age >1.85 million years, and locating additional hominin fossils situated in a

Introduction. Exhaustion of large oil and gas deposits leads to exploring smaller geological structures, from which large amount of core cannot be extracted.

Ichnotaxonomic assessment of Mazon Creek area trace fossils, Illinois, USA [PDF]
The Francis Creek Shale Member (FCSM) of the Mid-Pennsylvanian Carbondale Formation along Mazon Creek in northern Illinois is known for soft-bodied organisms preserved within siderite concretions.
