Botanical Garden of Helsinki, Finland. Victoria cruziana ( Santa Cruz water lily, water platter, yrupe, synonym Victoria argentina Burmeist.) is a tropical species of flowering plant, of the Nymphaeaceae family of water lilies native to South America, primarily Brazil, Bolivia, Argentina and Paraguay.This is a fossil trackway (cruziana) of multiple arthropods, collected near Erfoud, Morocco. A variety of different trackways can be seen throughout the stone, with distinguishable, partial trilobite tracks near the center. The slab of mudstone measures 10.4" by 6.7". It would be Ordovician in age, or approximately 450 million years old.Some scribbling trails (e.g., Cruziana) that cover the sediment surface are suggestive of such feeding strategies. These traces record both locomotion and feeding behaviors ( Seilacher, 1970 ). Most trilobites and worms are detritus or deposit feeder, and likely are source of traces such as Planolites, Rusophycus -type trace, Monomorphyichnus ...The tracemakers of both Cruziana and Rusophycus are bilaterally symmetrical organisms, most probably arthropods (Donovan, 2010). In Paleozoic strata, they occur exclusively in marine deposits and ...Cruziana semiplicata Salter is a well known ichnospecies, ascribed to trilobites. Despite that, there are still contradicting views on its origin (infaunal vs. epifaunal), the ethology represented (crawling vs. feeding) and the identity of its producer (a few trilobite genera were proposed).Victoria cruziana. 이 식물은 식물원에서 인기있는 수생 식물로, 최대 20 cm 높이의 두꺼운 테두리로 최대 2 m 너비의 잎이 최대한 닿을 수 있습니다. 지름 25 cm의 꽃이 수중 꽃 봉오리에서 발생하는 이틀 동안 꽃이 피고 둘째 날과 마지막 날에 진한 분홍색으로 변하는 흰 꽃입니다.

Carla Filgueira. 1994. The stratigraphic value of trilobite burrows has recently been questioned because of a seemingly Ordovician form in the Lower Cambrian of Canada. Closer examination shows, however, that the Cambrian homeomorph (Cruziana pectinata n. sp.) has a significantly different scratch pattern.Victoria cruziana (Santa Cruz waterlily) is one of only three tropical American aquatic species, bearing large, intricately engineered, buoyant, prickly leaves.V.amazonica is the most familiar of the three, with leaves reaching nearly 3m in diameter, while the leaves of V. cruziana grow up to 1m in diameter.Occurring in the waterways of Brazil and southern South America, V.The widest part of the trilobites shell leaves the parallel outer furrows and the leg movements create the diagonal marks in the center of the track. This Cruziana is preserved on thin slab of mudstone, and was collected near Erfoud Morocco and would be Ordovician in age or approximately 450 million years old.

Cruziana comprises over 30 ichnospecies mostly separated based on morphologic features resulting from the leg morphology of the producer (Seilacher, Reference Seilacher 1970, Reference Seilacher 1992). Cruziana is best interpreted as related to combined locomotion and feeding strategy (pascichnia) (Seilacher, Reference Seilacher 2007).In this study, Victoria cruziana was investigated as a model night-blooming water lily for floral scent biosynthesis.

Ichnology is the study of the fossilized tracks, trails, burrows and excavations made by animals and more broadly the study of bioturbation, which is the reworking of sediment by animals.
