Artist’s Reconstruction of Janavis finalidens

“Backwards” evolution – Discovery overturns more than a century of knowledge about the origin of modern birds

Artist’s reconstruction of the last known toothed bird, Janavis finalidens, in its native environment surrounded by the co-occurring “wonderchicken”, Asteriornis. 66.7 million years ago, parts of Belgium were covered by shallow seas and conditions were similar to modern tropical beaches in places like the Bahamas. Janavis was a very large seabird, with long wings and …

Researchers from Denmark and the United States used satellite data and numerical models to examine the loss of ice on the sheet since 2012. Pictured: Satellite image from August 2021 showing the disintegration of the Zachariae glacier

Melting Greenland Ice Sheet Could Raise Sea Levels 0.5 Inch By End Of Century

Melting of the northeast Greenland ice sheet could cause sea levels to rise by half an inch by the end of the century, a new study has warned. This equals the contribution made by the entire Greenland ice sheet over the past 50 years, meaning the rate of ice loss has been significantly underestimated. Researchers …
