Vertebrate Trace Fossils

Short Courses in Paleontology, 1992
The study of fossil footprints began soon after the birth of vertebrate paleontology. The Reverend Henry Duncan started a study of footprints from the New Red Sandstone (Permian) of Scotland in 1824 (Sarjeant, 1987). Even earlier reports of footprints are known, but the fossils were not studied until later (Sarjeant, 1975).

Trace Fossil Geometry

2018
The ichnofossils Treptichnus and Multina provide clues about the development of behavior in burrowing metazoans. A particular behavior type may be condensed and superimposed on the original burrowing pattern of programmed behavior. For example, a fine scale sinusoidal pattern may be superimposed on a large scale sinusoidal pattern.

Classification of Trace Fossils

1975
Classification is one of the tools of scientific discovery, no less so in the study of trace fossils than in any other science. Many different kinds of classification are possible. Simple descriptive classifications, although better than nothing, are of very limited value.

Trace Fossils in Archaeozoology

Journal of Archaeological Science, 1993
Abstract In classical palaeontology, the subdiscipline of palaeoichnology has reached a spectacular development. In archaeozoology, the analysis of trace fossils or ichnofossils focuses most often on marks left by animals and people on animal bone, but many other trace fossils exist.
