Footprints from at least six different species of dinosaur -- the very last dinosaurs to walk on UK soil 110 million years ago -- have been found in Kent, a new report has announced.
A new study in the Canadian Journal of Earth Sciences shows that medium-sized predators all but disappeared late in dinosaur history wherever Tyrannosaurus rex and its close relatives rose to dominance. In those areas -- lands that eventually became central Asia and Western North America -- juvenile tyrannosaurs stepped in to fill the missing ecological niche previously held by other carnivores.
The old cousins of the common woodlice were crawling on Irish land as long as 360 million years ago, according to new analysis of a fossil found in Kilkenny, Ireland.
A ball of 4,000-year-old hair frozen in time tangled around a whalebone comb led to the first ever reconstruction of an ancient human genome a decade ago. The hair, which was preserved in arctic permafrost in Greenland, was collected in the 1980s. It wasn't until 2010 that evolutionary biologist Professor Eske Willerslev was able to use pioneering shotgun DNA sequencing to reconstruct the genetic history of the hair. It sparked a 'decade of discovery.'
An international research team has described a new species of Oculudentavis, providing further evidence that the animal first identified as a hummingbird-sized dinosaur was actually a lizard.
A new species of large prehistoric croc that roamed southeast Queensland's waterways millions of years ago has been documented by University of Queensland researchers.
Paleoclimatologist Niels de Winter and colleagues developed an innovative way to use the clumped isotope method to reconstruct climate in the geological past on the seasonal scale. They show that dinosaurs had to deal with hotter summers than previously thought. The results suggest that in the mid latitudes, seasonal temperatures will likely rise along with climate warming, while seasonal difference is maintained. This results in very high summer temperatures.
A new study led by Penn paleontologist Aja Carter documents distinct patterns in how early amphibians' spines evolved. Certain modifications, the research team found, correlated with the animals' habitat: terrestrial or aquatic.
A more reliable way of estimating the size of megalodon shows the extinct shark may have been bigger than previously thought, measuring up to 65 feet, nearly the length of two school buses.
What's as long a basketball court, taller than a b-double and has just stomped into the record books as Australia's largest dinosaur? It's time to meet Australotitan cooperensis -- a new species of giant sauropod dinosaur from Eromanga, southwest Queensland.
