This view is looking at the bottom side of a siltstone bed. Collected August 2011.Moreover, we used transmission electron microscopy to observe ultrastructure of papillate‐conical epidermis in the stamen of Victoria cruziana. We then tested the phylogenetic or ecological distribution of these traits using both consensus network approaches and ancestral state reconstruction on fixed phylogenies.Two common traces — Cruziana and Rusophycus — are generally preserved as molds (fillings) on the basal contact of sandstones or carbonate beds in shales. One type of deep, inscribed, horizontal track or furrow, Cruziana, shows "V-like" scratch patterns made by the dactyls (claws) of the trilo-bite and a central groove corresponding to an ...Victoria cruziana,Water platter or Santa Cruz water lily (scientific name: Victoria cruziana) is native from Paraguay to Argentina and is an aquatic annual plant of the family Lilyaceae.

Due to morphological variation the ichnogenus Cruziana is subdivided into ichnospecies, e.g. C. acacensis, C. anchora, etc.Other articles where Amazon water lily is discussed: water lily: Major genera and species: The leaf margins of the Amazon, or royal, water lily (V. amazonica, formerly Victoria regia) and the Santa Cruz water lily (V. cruziana) have upturned edges, giving each thickly veined leaf the appearance of a large shallow pan 60 to 180 cm (about 2 to 6 feet) across and accounting…Besides, Victoria cruziana leaves exhibit an excellent load-bearing capacity. A mature leaf could withstand a compres-sive force of up to 500 N [13]. Victoria cruziana veins have porous sponge microstructures, which form numerous air chambers at the bottom of the leaves and endow the leaves with a large buoyancy [13,14].

This is a plate of fossil trackways (cruziana) from a burrowing trilobite, collected near Kansas City, Missouri. These are trackways preserved in a section of rock and would be Pennsylvanian in age. The longest trackway is 1.3" long and the rock measures 3.6 x 2".
