Ichnos, 1996
Lobichnus variabalis Kemper 1968 has, until now, previously only been reliably documented from the Cretaceous of north Germany. Herein, the ichnotaxon is recorded and described from the early Devonian (Lochkovian) Chapman Sandstone of the Dockendorff Group of Maine, northeastern U.S.A. This occurrence extends both the geographic and stratigraphie range

The brittle star Taeniaster bohemicus was found in association with the trace fossil Asteriacites lumbricalis in the Upper Ordovi‐cian of central Bohemia. Morphological features of the trace, coupled with spatial interrelationships between trace and body fossils, provide evidence that the brittle star represents the trace‐maker of this Asteriacites ...

Abstract The field of Ichnology bridges the gap between the areas of paleontology and sedimentology, but has connections to many subdisciplines within these areas. Biogenic structures record the behavior of their tracemakers and provide valuable information in paleoecologic and paleoenvironmental analysis.

Ichnos, 1997
There have been many research attempts to infer the track‐maker from a fossil footprint. However, it does not seem that prediction of the footprint from a mounted skeleton has yet been attempted. The body form of the desmostylian is hypothesized to have a peculiar lateral‐type limb posture.

Scratchings, forming two partial scratch circles, surround a narrow, filled tube probably formed by a plant stem. The scratchings are interpreted to have formed as follows: Water currents carrying sediment onto a floodplain swirled around the plant leaves, etching out partial scratch circles on the sediment surface.

The diagenetic and/or tectogenetic origins of stylolites now are universally accepted. However, when stylolites were first described and named by Karl Friedrich Kloden in 1828 and 1834, their origin was mysterious. K. F. Kloden, who investigated samples from the Mark Brandenburg, Germany, interpreted stylolites to be of biogenic origin and suggested ...

Abstract Analyses of deltaic facies successions highlight recurring ichnological patterns that reflect a variety of physicochemical stresses imposed upon infaunal organisms by the interaction of various delta-front processes. Analysis of numerous ancient deltaic deposits in Canada, the United States, Australia, and offshore Norway ...

Abstract This core workshop has been designed for sedimentologists and stratigraphers who utilize cores for interpreting depostional environments, identifying stratigraphic discontinuities, and applying high-resolution sequence stratigraphic (or other genetic stratigraphic frameworks) to the rock record.

Short Courses in Paleontology, 1992
Nobody knows exactly when and where Lady Ichnology was born; but everybody would agree that she is coming of age. There are unmistakable signs of this: social acceptance, for instance, or its own journal, and a progeny that can only be estimated from the yearly flow of publications and from a regular newsletter sent out in numbers that make book ...
