Medicine & TechnologyA newly discovered fossilized ancient relative of crabs, shrimps, and lobsters 430 million years old which are also exceptionally preserved including its complete soft-parts was named in honor of Sir David Attenborough.
The 423 million years old Sparalepsis fish fossil revealed the secrets of fish evolution. Researchers from Flinders University, Australia and the Institute of Vertebrate Paleontology and Paleoanthropology, China found this fossil from Southern China
For years the accepted theory was that dinosaurs were cold blooded, much like modern reptiles today. However, a study then showed that they were neither cold blooded or warm blooded like animals today. However, a paleontologist revisited that study focusing on the metabolism and growth of the dinosaurs. The re-analysis then provided evidence that dinosaurs were actually warm blooded like many of today's modern animals.
In the long debate over whether dinosaurs were warm or cold blooded, a study published last year in Science was thought to have put the issue to rest. Dinosaurs were neither, according to the paper. Instead, they occupied an intermediate category. But a reanalysis of the same data has drawn new conclusions. And the verdict this time? Warm blooded.
In 2012, a team of paleontologists were scouring the rocky shores of what is today the small island of Sucia, located within Puget Sound, between Washington State and Vancouver Island. On the hunt for prehistoric shells, they inadvertently stumbled upon the bone of a creature never known to have ranged that far north - a dinosaur.
In the world of dinosaurs, not everything was as it seems. The most advantageous appendages may have just been for show-and-tell, to ward off unassuming predators, and some of the most evolutionarily superb tricks may never be revealed in the fossils we find today. And with the endless wonder of discovering an entirely unique world, unlike our own, paleontologists, like children, keep learning in the hopes of one day adding their own discovery into the dialogue. The only difference is that one of these differences was recently discovered in a new species of dinosaur related to the Tyrannosaurus rex, but this discovery really was made by a child—seven-year-old Diego Suárez.
News this week revealed a frightening new addition to the fossil record—a “Terror Bird” species known more scientifically as Llallawavis scagliai (aka Scaglia’s Magnificent Bird). But in spite of its massive size and terrifying stance, this top-tier predatory may not have been the most well-adapted hunter that it could be… That is, unless it was hunting in packs.
Think that you don’t have what it takes to start a career in paleontology, even though your fascination with dinosaurs never ends? Well never fear, news this week reveals that you’re never too old, or too young, to start on the hunt for dinosaurs. And 4-year-old Wylie Brys, of Mansfield, Texas, is proving this sentiment true.
Think that we’ve found just about every prehistoric species that there is to find? You’d be terrifyingly wrong if you said yes. In fact, adding a new view on the diversity of some unlikely large predators that predate humans, a new fossil this week revealed another species of South American “terror birds” known as Llallawavis scagliai.
When you watch butterflies flutter through the sky and lobsters waddle in the sea, you may not readily believe that the two far off species have anything in common. But along with spiders, butterflies and lobsters share quite an interesting collective history-one where an ancient ancestor may have emerged from the sea. Cover the ocean, the land and the skies above the radiation of species into many forms are believed to have originated with a common ancestor as long as 508 million years ago. And in a new study published this week in the journal Paleontology researchers are finally giving a face to ancestor known as Yawunik kootenayi.
Scientists have unearthed fossils in North Carolina of a large land-dwelling crocodile that lived about 231 million years ago, walked on its hind legs and was the top land predator before dinosaurs even appeared.
