Fluvial deposits of the uppermost Stockton Formation (Late Triassic), west-central New Jersey have yielded the trace fossils Cruziana tenella and Helminthopsis isp. The ichnotaxa belong to the Scoyenia ichnofacies. On the basis of stratification and primary sedimentary structures, the beds are interpreted as deposits in a meandering stream environment.Cruziana is a common and widespread trace fossil in Lower Palaeozoic strata that is generally attributed to the activity of trilobites. The Lower to Middle ...Cruziana is one of the most recognizable trace fossils ascribed to arthropods. It ranges throughout the Phanerozoic and encompasses a diverse set of morphologies. The distinct features of Cruziana have incited fierce debate regarding its mode of formation.

Small, dirt-colored dove of desert lowlands, where it is often common in towns, parks, farmland, and semiopen areas in general. In pairs or small groups; feeds on the ground but often perches on wires. Flight is rather fast and direct, and usually low. Readily identified by diagnostic bright orange base on a rather stout (for a dove) bill. Male has more blue-gray tones than pinkish female.Cruziana: Diplichnites: A very detailed Rusophycus specimen from Australia show gnathobase impressions along the midline, as well as the bi-lobed, oval impression of the trilobite body. Cruziana trail showing the central paired leg grooves and the parallel furrows on the outside edges. The curved shape suggests a searching pattern.The ichnogenus Planolites frequently intersects the Cruziana. This sub-horizontal burrow made by vagile endobenthic vermiform deposit feeders represents a slightly deeper tier, occupied later than the Cruziana, but targeting the same widely distributed food resources as the trilobites that produced the Cruziana (Neto de Carvalho and Baucon 2016).Santa Cruz Water Lily (Victoria cruziana) The Santa Cruz Water Lily flowering plant is another of Argentina's indigenous plants.
