The trilobite trace fossils present in the Lower Cambrian rocks of the WhiteInyo Mountains, California belong to the genera Cruziana d'Orbigny (crawling furrows), Rusophycus Hall (resting burrows), Diplichnites Dawson (walking trackways), and Monomorphichnus Crimes (parallel scratchmarks). New species described are Rusophycus radwanskii and Monomnorphichnus multilineatus. Three star-like trace fossils, comparable to Asteriacites Schlotheim, Astropolithon Dawson, and Dactyloidites Hall, are described from the Lower Cambrian rocks. Dactyloidites is interpreted as lobate feeding burrows
