Cruziana

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. Ichnologists use ichnofossils or trace fossils to interpret paleoecological aspects of sedimentary environments. The underpinnings of ichnology depend upon ...

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.Thus, the measured stiffness coefficient of V. cruziana K Victoria is significantly larger than that of a floating disk of uniform thickness, K Victoria K disk ≈ 5 to 10 (equivalently, a circular disk with comparable bending stiffness to that of the measured leaves requires a volume in the range V disk = πR 2 t disk ≈ 7200 to 11,900 cm 3 ...

Rare and small, the Cruziana specimens occur in overall outcropping surfaces, associated with Diplichnites, Diplopodichnus, and Umfolozia.
