Hydrodynamics of fossil fishes (2014)
Journal Article

From their earliest origins, fishes have developed a suite of adaptations for locomotion in water, which determine performance and ultimately fitness. Even without data from behaviour, soft tissue and extant relatives, it is possible to infer a wealt... Read More about Hydrodynamics of fossil fishes.

One of the most striking features of meandering rivers are quasi-regular ridges of the point bar, evidence of a pulsed lateral migration of meander bends. Scroll bars formed on the inner bend are preserved on the point-bar surface as a series of ridg... Read More about Bank pull or bar push: What drives scroll-bar formation in meandering rivers?.
