A 325 million-year-old fossil find shows that the gill structures of modern sharks are actually quite different from their ancient ancestors.

For instance, a new nozzle design, inspired by shark gill structures, was shown to improve mixing and reduce the vibration amplitudes in rod bundle assemblies, thus enhancing operational safety in ...

New Fossil Provides Insight Into Shark EvolutionNow, a well-preserved, 325-million-year-old shark-like fossil from Paleozoic Arkansas shows how the skeletal structure that supports the gills of a ...

But a new study of a 325-million-year-old shark fossil found in Arkansas suggests modern sharks have evolved significantly from their bony ancestors.

But the most striking feature of all is a gill structure that foreshadows that of modern vertebrates. They have an array of bipartite bars, or pairs of curved structures for supporting gills (also ...

A study of shark skin has led to a new structure that could one day improve the aerodynamic performance of planes, wind turbines, and cars.

Researchers at the University of Cambridge have shown that human limbs share a gene with the gills of cartilaginous fish such as sharks, skates and rays.
