Ancient Footprints
Footprints have been preserved as fossils and provide evidence of prehistoric life. Known as "ichnites", these trace fossils can give clues to the behaviour of specific species of dinosaur. The study of such fossils is known as ichnology and species known only by such evidence are known as ichnospecies. The Grallator is one example of a genus that has left no fossils other than ichnites.
For example, an international team's discovery of a set of 1.5 million-year-old human ancestor footprints in Ileret, Kenya has shown the earliest direct evidence of a modern human style of upright walking. The team believe that the prints were probably formed by the species Homo erectus.

Famous quotes containing the words ancient and/or footprints:
“To some extent, mythology is only the most ancient history and biography. So far from being false or fabulous in the common sense, it contains only enduring and essential truth, the I and you, the here and there, the now and then, being omitted. Either time or rare wisdom writes it.”
—Henry David Thoreau (1817–1862)
“Morning at last: there in the snow
Your small blunt footprints come and go.”
—Philip Larkin (1922–1986)
