Lithographus (‘rock writing’[2]) is a Carboniferous[3] to Cretaceous[1] trace fossil that has been found in North America, South America, Europe, and east Asia.

[1] The ichnogenus is characterized by alternating groups of three tracks arranged in an arrow shape.

These are interpreted as tracks of cockroaches, beetles, or similar insects.

[2][1] The tracks are likely produced on relatively dry surfaces where the insect's legs do not drag; on wetter sediments, a more continuous trackway is created that is sometimes assigned to Grammepus.
