Remarks on Some Fossil Impressions in the Sandstone Rocks of Connecticut River

Remarks on Some Fossil Impressions in the Sandstone Rocks of Connecticut River, published in 1854 by John Collins Warren, is a scientific exploration of fossil footprints found in the Connecticut River Valley. The work focuses on ichnology, detailing various fossilized tracks, particularly those of birds and reptiles, and discusses the evolutionary significance of these findings. Warren's examination includes notable species such as Ornithichnites and the giant Epyornis, contributing to the understanding of paleontology in the mid-19th century.
