Fossilized ticks discovered trapped and preserved in amber show that these parasites sucked the blood of feathered dinosaurs almost 100 million years ago, according to a new article published in Nature Communications today.
A study by the University of Cincinnati found that the rare Henst's goshawk of Madagascar hunts lemurs in low-lying areas that are most at risk to deforestation. Researchers could use this isotope analysis to study the habitat and prey needs of other threatened species that are difficult to track.
New paleontological research shows that during the late Permian, the equator was dry and desert-like, yet surprisingly a hotspot for biodiversity. Similarly to modern rainforests, equator ecosystems were home a unique diversity of species, including those both anciently and newly evolved. After the late Permian extinction, this diversity was decimated, and the climate change event that triggered an extinction back then is informative as we move forward with protecting our planet's species diversity.
A new study led by Oxford University Museum of Natural History has revealed that an extinct group of marine reptiles called sauropterygians evolved similar inner ear proportions to those of some modern day aquatic reptiles and mammals. The research is published in Current Biology today.
A 530-million-year-old fossil contains what could be the oldest eye ever discovered, a study reveals.
Little Foot is the only known virtually complete Australopithecus fossil discovered to date. It is by far the most complete skeleton of a human ancestor older than 1.5 million years ever found. It is also the oldest fossil hominid in southern Africa, dating back 3.67 million years. For the first time ever, the completely cleaned and reconstructed skeleton was viewed by the national and international media.
A well-preserved dinosaur skeleton from Mongolia unites an unexpected combination of features that defines a new group of semi-aquatic predators related to Velociraptor. Detailed 3-D synchrotron analysis allowed an international team of researchers to present the bizarre 75-million-year-old predator, named Halszkaraptor escuilliei, in Nature. The study not only describes a new genus and species of bird-like dinosaur that lived in Mongolia but also sheds light on an unexpected amphibious lifestyle for raptorial dinosaurs.
A team of Australian scientists has discovered a new species of marsupial lion which has been extinct for at least 19 million years. The findings, published in the Journal of Systematic Palaeontology, are based on fossilized remains of the animal's skull, teeth, and humerus (upper arm bone) found by University of New South Wales scientists in the Riversleigh World Heritage Area of remote northwestern Queensland.
For many species, rarity is not a guarantee of impending extinction. Instead, the traits that enable some species to be rare may hold the ticket to their survival. A paper from UC Davis predicts what these traits might be and how having them could place chronically rare species at an advantage during crises.
Paleontologists at Ludwig-Maximilians-Universitaet in Munich correct a case of misinterpretation: the first fossil 'Archaeopteryx' to be discovered is actually a predatory dinosaur belonging to the anchiornithid family, which was previously known only from finds made in China.
