The Lower to Middle Ordovician Armorican Quartzite Formation ...Victoria cruziana, a tropical species of the Nymphaeaceae family of water lilies, has evolved a network of three-dimensional and rugged veins, which yields a superior load-bearing capacity ...In general, trace fossils are poor stratigraphical markers. However, some periods (e.g. in the lower Paleozoic) have been successfully dated by means of trace fossils (e.g. ichnospecies of Cruziana).This procedure might be helpful in exploration activities of large basins with relatively few data as demonstrated in North Africa.

Victoria cruziana, a tropical species of the Nymphaeaceae family of water lilies, has evolved a network of three-dimensional and rugged veins, which yields a superior load-bearing capacity. However, it remains elusive how biological and mechanical factors affect their unique vein layout.Crimes TP (1975) The stratigraphical significance of trace fossils.

Crimes TP (1987) Trace fossils and correlation of late Precambrian and early Cambrian strata. Geol Mag 124 (2):97–119.Jun 15, 2022 · 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]. Though the biological functions of Victoria cruziana veins have been recognized, it remains unclear how their optimal topology is influenced by biomechanical factors. Figure 1. Trilobite Tracks Cruziana is a trace fossil consisting of elongate, bilobed, approximately bilaterally symmetrical burrows. They are usually preserved along bedding planes, with a sculpture of repeated striations that are mostly oblique to the long dimension.

The Cruziana ichnofacies is characteristic of shifting to stable media in such moderate- to low-energy offshore marine settings as shelves, epeiric seas, and littoral to sublittoral portions of estuaries, bays, lagoons, and tidal flats (Fig. 13). These settings typically experience minimal to considerable amounts of sedimentation.The Cruziana ichnocoenosis records the resident fauna of a protected, lower intertidal to subtidal interbar setting. The Skolithos ichnocoenosis is represented by high to low density vertical burrows of Skolithos linearis, which extend downwards to the quartzose sandstone soles of faciès B and cross the Cruziana ichnocoenosis. The Skolithos ... ….

However, virtually identical Cruziana and Rusophycus have been reported from the nearby estuary of the Piedras River (Lepe, Huelva, Spain), being attributed to the feeding activity of the perciform fish Diplodus vulgaris (Muñiz et al., 2015). The same traces have been found in the Grado lagoon of NE Italy (Baucon, 2008, fig. 16d), therefore ...I was doing some research on the ordovician cruziana plates I found in Millard Co, Utah a few years ago and noticed something funny.
