Even when it's been dead for 110 million years, a shiver of fear might be expected on encountering the remains of a predator whose jaw is longer than many people. Robert Hacon was spraying weeds on his property in western Queensland when he noticed something sticking out of the ground. Drought in the area had killed the grass and made previously hidden rocks visible. Hacon saw light reflecting off the bone, but “thought they were muscle shells so...
Reading these articles makes me wish I had a time machine so that I could see these creatures firsthand. The closest I've come is a Disney ride :/. Maybe soon there will be a virtual reality environment to showcase these creatures.
+Rick Durrett just finished his talk at the Evolutionary Game Theory meeting at Ohio State University. You can follow his (and other talks) following +Ruchira Datta's stream. But if you want to know more about his work, here's the link to one interesting paper.
The internet is a testament to how much we love animals. When people aren’t busy looking up cute cat videos, they are sharing random facts about their favorite animal. There is just one problem, though – a lot of these “facts” are plain wrong. 1. A Duck’s quack doesn’t echo
The article gets some "facts" wrong too. Red is not used because people thought that bulls attacked red (as attested by the matador's assistants who use their capes which are faded pink on one side and yellow on the other).
It's rather a chicken and the egg thing... the human spectators will certainly be more sensitive to red, and so it is used to denote the matador. The whole theory that "bulls attack red" probably came after this custom was established.
A new feathered dinosaur unearthed from Jurassic rocks in northeastern China had long bones protruding from its wrists that may have supported wing membranes—like the kind you’d find in bats and flying squirrels, not birds. Yi qi, as the critter is called, is an extraordinary example of early evolutionary experiments with flight. Although ultimately, it may have been a failed experiment. The findings were published in Nature this week.
We are starting to find a lot of interesting evolutionary dead ends as the fossil record continues to expand. Some big questions remain though on the authenticity of some of these fossils; there was one from a Chinese site not long ago that was eventually shown to have been significantly altered.
