Traces of a trauma 245 million years ago
Traces of a trauma 245 million years ago
Researchers gain insight into life in an ancient sea With a broken jaw on the prowl - that seems almost impossible. But researchers have discovered an approximately 245-million-year-old nothosaur fossil on which the injury had healed. The international team, with participation from the University of Bonn, examined other marine reptile bone anomalies from a site near the town of Winterswijk in the Netherlands.

The vertebral column develops in the same way in modern animals as it did 300 million years ago
Ancient fossils reveal the evolutionary history of ossification in the spine of land vertebrates A study conducted by researchers from the Museum für Naturkunde in Berlin revealed the evolution of ossification patterns in the backbones of four-legged vertebrates. Antoine Verričre and his colleagues were able to reconstruct the patterns of how the bones in the vertebral column formed in the ancestor to all land vertebrates based on a large dataset of modern and fossil vertebrates with the inclusion of rare new data from the 300 Ma old reptile Mesosaurus tenuidens.

'Veggie' dinosaurs differed in how they ate their food
’Veggie’ dinosaurs differed in how they ate their food
Scientists discover differences in the way early herbivore dinosaurs ate their food Although most early dinosaurs were vegetarian, there were a surprising number of differences in the way that these animals tackled eating a plant-based diet, a new study reveals. Scientists used CT scans of dinosaur skulls to track the evolution of early dinosaur herbivores - reconstructing jaw muscles and measuring the animals' bite force to understand how dinosaur feeding evolved.

The oldest bearded vulture nest in the Iberian Peninsula
The oldest bearded vulture nest in the Iberian Peninsula
Coprolites, or fossil faeces from around 30,000 years ago, have been used to identify the presence of bearded vultures ( Gypaetus barbatus ) at the Palaeolithic site of Lagar Velho (Portugal). A comparison of the coprolites found in the excavations with the faeces of present-day lammergeyers has confirmed the presence of these animals in the past.

Giant arthropods dominated the seas 470 million years ago
An international team of scientists has made a groundbreaking discovery at a major new fossil site in Morocco: giant arthropods - relatives of modern animals such as shrimps, insects and spiders - would have dominated the seas 470 million years ago. The excavations were carried out in Taichoute, in Morocco, on a site formerly underwater but today desert.

What the inner ear of Europasaurus reveals about its life
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.

Climate change played key role in dinosaur success story
Climate change played key role in dinosaur success story
Climate change, rather than competition, played a key role in the ascendancy of dinosaurs through the Late Triassic and Early Jurassic periods. According to new research, changes in global climate associated with the Triassic-Jurassic mass extinction - which wiped out many large terrestrial vertebrates such as the giant armadillo-like aetosaurs - actually benefitted the earliest dinosaurs.

Prehistoric reptile casts turn out to be copies of priceless fossil destroyed in WWII
Scientists find copies of lost fossil destroyed in WWII hiding in a US museum. The world's first complete skeleton of a prehistoric reptile brought to the attention of science was discovered a little over 200 years ago and named ' Proteosaurus '. Unfortunately, that fossil was destroyed in an air raid in May 1941, during WWII, with no copies thought to exist.

Glowing fossils: fluorescence reveals colour patterns of earliest scallops
Glowing fossils: fluorescence reveals colour patterns of earliest scallops
Göttingen University geobiologist discovers diversity of patterns in 240 million-year-old seashells UV light makes it possible to see intricate structures of fossils that are barely visible in normal daylight. This method has often been used on the fossilised seashells from the Earth's current geological era to reveal patterns of colour that had long since faded away.

New Scottish fossil sheds light on the origins of lizards
New Scottish fossil sheds light on the origins of lizards
A fossil discovery from Scotland has provided new information on the early evolution of lizards, during the time of the dinosaurs, reports a study involving UCL researchers. The tiny skeleton discovered on the Isle of Skye, called Bellairsia gracilis , is only 6 cm long and dates from the Middle Jurassic, 166 million years ago.

Vocal Communication Originated over 400 Million Years Ago
Vocal Communication Originated over 400 Million Years Ago
Acoustic communication is not only widespread in land vertebrates like birds and mammals, but also in reptiles, amphibians, and fishes. Many of them are usually considered mute, but in fact show broad and complex acoustic repertoires. According to researchers at University of Zurich, the evolutionary origin of vocal communication dates back more than 400 million years.

Neanderthals appear to have been carnivores
Neanderthals appear to have been carnivores
For the first time, zinc isotope ratios in tooth enamel have been analysed with the aim of identifying the diet of a Neanderthal. Other chemical tracers indicate that this individual did not consume the blood of their prey, but ate the bone marrow without consuming the bones. A new study published on october 17th in the journal PNAS , led by a CNRS researcher, has for the first time used zinc isotope analysis to determine the position of Neanderthals in the food chain.

To be heavy or not - that is the question
To be heavy or not - that is the question
Researchers at the University of Bonn study the way of life of extinct amphibians If you need to lurk at the bottom of a water body waiting for prey, it is wise to stay motionless without resisting against the buoyant forces of water. To do so you need a kind of diving belt that helps to sink. One large amphibian species Metoposaurus krasiejowensis, that lived more than 200 million years ago, compensated for buoyancy with a heavy shoulder girdle.

Ancient 'sharks' appeared much earlier than previously thought
Ancient 'sharks' appeared much earlier than previously thought
The first appearance of shark-like 'jawed fish' may have happened some 15 million years earlier than previously thought, according to new evidence. A handful of fossil teeth from a completely new species, uncovered from rock samples found in China, suggest jawed fish emerged some time at the end of the Ordovician, or beginning of the Silurian period, around 440 million years ago.
