There are many developing specialities such as paleobiology, paleoecology, ichnology ( the study of tracks and burrows ) and taphonomy ( the study of what happens to organisms after they expire ).

The study of traces-ichnology-divides into " paleoichnology ", or the study of trace fossils, and " neoichnology ", the study of modern traces.

In 1930, the octogenarian Aldrich named new ichnogenera of fossil footprints that were discovered in a University of Alabama coalmine in Walker County, Alabama his only venture into the field of ichnology.

While ornithology was his main passion, he also studied ichthyology, botany and geology, writing a work on burrows and traces, the " Ichnology of Annandale ", his ancestral estate.

The advent of the Dinosaur Renaissance and the publication by R . McNeil Alexander of a formula which could reconstruct their running speed based on data from fossil trackways brought renewed interest and prestige to ichnology during the late 20th century.

Charles Darwin's " The Formation of Vegetable Mould through the Action of Worms " } } is an example of a very early work on ichnology, describing bioturbation and, in particular, the burrowing of earthworms.

That year, Amherst College professor Edward Hitchcock began systematically collecting fossils from the Connecticut Valley, creating a unique ichnology ( the study of prehistoric tracks and traces ) collection now on view in the college's Pratt Museum of Natural History.

Begun when the science of ichnology ( the study of tracks ) was unknown and made chiefly from the fossils of the Connecticut River Valley ( Connecticut River Valley trackways ), by 1875 this collection consisted of 21, 773 tracks representing 120 species.

In the field of ichnology, Brand, along with Thu Tang, Andrew A . Snelling, and Steven Austin has proposed that fossil tracks in the Grand Canyon's Coconino Sandstone point to underwater deposition, rather than desert wind deposition of dry sand.
20.
In ichnology, "'underprints "'( also known as "'transmitted prints "'or "'ghost prints "') are fossil footprints that are preserved in a sedimentary level beneath that which was directly imprinted upon by the foot of the trackmaker.
