Between shark and ray: The evolutionary advantage of the sea angels
Threatened with extinction despite perfect adaptation Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape.

First fossil nursery of the great white shark discovered
Paleo-kindergarten ensured evolutionary success millions of years ago An international research team led by Jaime A. Villafaña from the Institute of Palaeontology at the University of Vienna discovered the first fossil nursery area of the great white shark, Carcharodon carcharias in Chile. This discovery provides a better understanding of the evolutionary success of the largest top predator in today's oceans in the past and could contribute to the protection of these endangered animals.

Giant teenage shark from the Dinosaur-era
Fossil vertebrae give insights into growth and extinction of an enigmatic shark group Scientists of the University of Vienna examined parts of a vertebral column, which was found in northern Spain in 1996, and assigned it to the extinct shark group Ptychodontidae. In contrast to teeth, shark vertebrae bear biological information, like body size, growth, and age and allowed the team surrounding Patrick L. Jambura to gain new insights into the biology of this mysterious shark group.
