Floral Time Travel: Flowers Were More Diverse 100 Million Years Ago Than They Are Today
Angiosperm flowers reached their greatest morphological diversity early in their evolutionary history An international team of researchers around botanists at the University of Vienna, Austria, has now analyzed the morphological diversity of fossilized flowers and compared it with the diversity of living species.

Dynamic plants: Origin and geographic evolution of cycads clarified
Distribution in the Mesozoic from present-day Antarctica to Greenland Paleobotanist Mario Coiro of the Institute of Paleontology at the University of Vienna and colleagues at the University of Montpellier (France) have made an important breakthrough in understanding the origin and geographic distribution of cycads.

’Jurassic Shark’ - shark from the Jurassic period already highly developed
Molecular biology phylogenetic tree provides new insights into cartilaginous fish evolution Cartilaginous fish have changed much more in the course of evolution than previously assumed. Evidence for this thesis was provided by molecular biological data on fossil remains of Protospinax annectans , an already highly evolved shark from the late Jurassic.

What the inner ear of Europasaurus reveals about its life
A long-necked dinosaur from northern Germany was a so-called nest fledger Europasaurus was a long-necked, herbivorous dinosaur on four legs. The dinosaur lived in the late Jurassic period about 154 million years ago on a small island in what is now northern Germany. Researchers from the Universities of Vienna and Greifswald have now examined fossil skull remains of Europasaurus using computer tomography.

Within a dinosaur’s head: ankylosaur was sluggish and deaf
German and Austrian scientists took a closer look at the braincase of a dinosaur from Austria. The group examined the fossil with a micro-CT and found surprising new details: it was sluggish and deaf. The respective study got recently published in the scientific journal scientific reports. Ankylosaurs could grow up to eight meters in body length and represent a group of herbivorous dinosaurs, also called 'living fortresses': Their body was cluttered with bony plates and spikes.

New ancient shark discovered
In a new study, an international team led by Sebastian Stumpf from the University of Vienna describes a fossil skeleton of an ancient shark, which is assigned to a new, previously unknown genus and species. This rare fossil find comes from the Kimmeridge Clay Formation in England, a series of sedimentary rocks that was formed in a shallow, tropical-subtropical sea during the Upper Jurassic, about 150 million years ago.

Spectacular fossil discovery: 150 million-year-old shark was one of the largest of its time
In a new study, an international research team led by Sebastian Stumpf from the University of Vienna describes an exceptionally well-preserved skeleton of the ancient shark Asteracanthus. This extremely rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago.

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.

Fossil fish gives new insights into the evolution
"An experiment of nature" after the end-Cretaceous mass extinction An international research team led by Giuseppe Marramà from the Institute of Paleontology of the University of Vienna discovered a new and well-preserved fossil stingray with an exceptional anatomy, which greatly differs from living species.
