About 55.8 million years, the rate of carbon emissions grew abruptly, leading to a period of massive warming. But today's rate of emissions is ten times higher.
Paleontologists have discovered what looks like the earliest member of the Corytophanidae (also known as casquehead or helmeted lizards) judging from fossils collected in Wyoming. The ancient species is also the earliest ancestor of the modern basilisk, or better known as the Jesus Lizard because of its ability to skim the surface of water over short distances.
Saber-tooth cats, the bane of early humans (and pretty much every creature that co-existed with them), roamed the Earth for 42 million years before going extinct at the end of the ice age. Now, a new study has found that their trademark teeth may have evolved later in their evolutionary stage, but when they grew, they grew […]
Researchers have discovered the earliest evidence of a bird pollinator visiting flowers, presumably to feed on the nectar – if true, this means that bird pollinator/plants interactions were already taking place 47 million years ago. When you think about pollinators, you mostly think about bees or butterflies – but birds are significant pollinators too. Birds, particularly […]
Scientists have used one of the brightest light sources in the Universe that we know of to expose the biochemical structure of a 50 million-year-old fossil plant to stunning visual effect. The mixed team of paleontologists, geochemists and physicists bombarded the fossils with extremely bright X-rays and showed that the chemical makeup of the plant […]
Cats, dogs, as well as many well known and loved wild animals such as seals, lions, tigers and bears trace their ancestry to primitive carnivorous mammals dating back to 55 million years ago, at the beginning of a time period called the Eocene. A study, published in the most recent issue of the Journal of […]
Scientists who studied sediment cores drilled from the ocean floor off the Antarctic coast, have found on subsequent analysis fossil pollens that came from a tropical forest. Most likely, the continent was covered by rainforest some 52 million years ago. The researchers involved warn however that by the end of the century, ice from the […]
After the great dinosaur extinction some 65 million years ago, mammals finally had their big shot as numerous niches became free for the taking. Thus, from mouse size, some mammal species surfaced which were as large as a bus, the so called mammal megafauna, like mammoths, giant sloths or saber-tooth tigers. However, a dire trial of their […]
A newly published paper in the journal Science provides a worrisome report – the world’s oceans are acidifying at a rate, which if set to continue, will be unprecedented in the last 300 million years. The scientists report that this comes as a direct consequence of the alarming ever increasing carbon dioxide concentration in the atmosphere, […]
Bergmann’s rule states that mammals of a given genus or species are smaller in hotter climates, and bigger in colder climates. Adapted, when faced with climate change cycles, mammals shirk as temperature rises and scale back up in size, once the cycle ends and makes room for cooling. Simple correlation, based on fossils and temperature readings […]
