Electronic Dinosaur Toys, The Advantages of Having Feathers A Comparison with Modern-Day Birds. Some paleontologists contend that such a four-winged configuration implies that flight evolved through a four-winged gliding stage. In this case, Sciurumimus indicates that simple feathers were an early, common theropod trait that evolved close to the origin of the group.

Sure, the dinosaurs arent covered from head to toe in downy feathers in the exhibits, but even just a few feathers on their heads or bodies really change how we see theT. Rex. [48] Paleontological and evolutionary developmental studies show that feathers or feather-like structures were converting back to scales.

I doubt that anyone who says this has ever been up close and personal with a Golden Eagle, or seen one dive out of the Mongolian sky on a fox or a wolf.

We dont know yet what kind of surface covered all the big dinos, and such mammals as elephants and rhinos show that most hair, or feathers, can disappear on large animals that live in a warm climate. This view began to shift during the so-called dinosaur renaissance in scientific research in the late 1960s, and by the mid-1990s significant evidence had emerged that dinosaurs were much more closely related to birds, which descended directly from the theropod group of dinosaurs. [61] More recently, findings in Russia of the basal neornithischian Kulindadromeus report that although the lower leg and tail seemed to be scaled, "varied integumentary structures were found directly associated with skeletal elements, supporting the hypothesis that simple filamentous feathers, as well as compound feather-like structures comparable to those in theropods, were widespread amongst the whole dinosaur clade. Science illustrators are already embracing the new ideas, drawing and discussing cutting-edge paleontological ideas daily on their blogs. There are lots of misconceptions that films and TV have taught us. In 2012, Darren Naish wrote on his Scientific American blog about the recent discovery of Yutyrannus, an animal only slightly smaller than T. rex (10 meters from snout to tail tip), that lived in a region that had snow during the Cretaceous winters.
