Examining fossilized pigments, scientists from the University of Bristol have uncovered new insights into blue color tones in prehistoric birds.
High-resolution microscopic images of the surface of dental enamel of lepidosauria, which is a subclass of reptiles including monitor lizards, iguanas, lizards, and tuatara, allow scientists to determine their dietary habits. The enamel wear patterns reveal significant differences between carnivores and herbivores, but also allow finer distinctions, such as between algae-, fruit-, and mollusk-eating species. These findings are the result of research by a team led by scientists at Johannes Gutenberg University Mainz.
A team of University of Copenhagen researchers has compiled the first and only evidence that narwhals and beluga whales can breed successfully. DNA and stable isotope analysis of an anomalous skull from the Natural History Museum of Denmark has allowed researchers to confirm the existence of a narwhal-beluga hybrid.
New UC Riverside-led research settles a longstanding debate about whether the most ancient animal communities were deliberately mobile. It turns out they were, because they were hungry.
A new study shows how marine life around Antarctica returned after the extinction event that wiped out the dinosaurs. A team led by British Antarctic Survey studied just under 3,000 marine fossils collected from Antarctica to understand how life on the sea floor recovered after the Cretaceous-Paleogene (K-Pg) mass extinction 66 million years ago. They reveal it took one million years for the marine ecosystem to return to pre-extinction levels.
Sorting out the way these 570- to 540-million-year-old, enigmatic creatures ate supports the argument that they behaved like more modern-looking animals and evolved into shapes that helped them feed.
Newly developed geological techniques help uncover the most accurate and high-resolution climate records to date, according to a new study. The research finds that the standard practice of using modern and fossil coral to measure sea-surface temperatures may not be as straightforward as originally thought. By combining high-resolution microscopic techniques and geochemical modeling, researchers are using the formational history of Porites coral skeletons to fine-tune the records used to make global climate predictions.
Scientists went looking for preserved collagen, the protein in bone and skin, in dinosaur fossils. They didn't find the protein, but they did find huge colonies of modern bacteria living inside the dinosaur bones.
Underneath their tough exteriors, some crocodilians have a sensitive side that scientists could use to shine light on our ancient climate, according to new findings published in the Journal of Vertebrate Paleontology.
Modern hyenas are known as hunters and scavengers in Asian and African ecosystems such as the savanna. But in ancient times, these powerful carnivores also roamed a very different landscape, inhabiting the frigid Arctic during the last ice age. A new study reports on the first hyena fossils discovered in the Arctic -- two teeth.
