The U-shaped relationship between diet and size in modern land mammals could also stand for "universal," says a new study, which has found that the relationship spans at least 66 million years and a range of vertebrate animal ...
Ichthyosaurs are a group of successful Mesozoic marine reptiles that have a worldwide distribution, but their evolutionary origin is still unclear. In recent years, many new marine reptiles related to ichthyosaurs, and called ...
A new study published in PeerJ uses modern methods to understand the preservation of unique ichthyosaur fossils. Two new ichthyosaur specimens—one complete animal and one tail—are the first to preserve outer body shape in ...
The later stages of pregnancy can make life difficult as the fetus presses against the diaphragm, making it hard to breathe. But snakes that constrict their victims before swallowing them whole have to overcome the challenges ...
Foxes kill about 300 million native mammals, birds and reptiles each year, and can be found across 80% of mainland Australia, our devastating new research published today reveals.
Researchers from the Charles University in Prague reconstructed the evolution of brain neuron numbers in amniotes and revealed that mammals and birds have dramatically increased neuron numbers in brain parts associated with ...
Aaron Bauer has traveled the world in search of lizards, logging more than 2 million miles in his quest to identify new species and determine how they fit into the tree of life. He has made more than 100 trips to southern ...
About 200 million years ago, much of Europe was transformed by a huge flood. What had been land, occupied by early dinosaurs and other reptiles, was covered by shallow seawater, from Poland in the east to Wales and south-west ...
The fossilized remains of a gigantic ichthyosaur, colloquially known as a "sea dragon," were recently uncovered at the Rutland Water Nature Reserve in the UK. Measuring at least ten meters in length and with a skull weighing ...
New Zealand's fossil record of land dinosaurs is poor, with just a few bones, but the collection of ancient extinct marine reptiles is remarkable, including shark-like mosasaurs and long-necked plesiosaurs.
