Cruziana es un icnogénero de icnofósil —huella de actividad de un ser vivo— que corresponde a las huellas de reptación de trilobites en los fondos marinos del Paleozoico , desde hace de unos 570 a 360 millones de años atrás. Esas arenas hoy son rocas muy duras, cuarcitas o cuarzoarenitas. Es posible ver cuarcitas de apenas un centímetro hasta unos diez o quince centímetros de anchura.Full reliefs of Cruziana furcifera from the Lower-Middle Ordovician quartzite sandstone beds (Pochico Formation, southern Spain) points to deep, infaunal burrowing of trilobites. Some specimens show an unusual vertical extension with a wider lower part and a narrower upper part in cross section. They are referred to trilobites, which burrowed deeply in the sediment and were oriented obliquely ...
