    Scientists Find a Missing Link

    By Stuart Fox Posted on 1.19.2009 8 Comments

    Paleontologists have excavated a plethora of feathered dinosaurs in China over the past few years have, but none of those dinosaurs had feathers like this. Scientists examining a news specimen of the dinosaur Beipiaosaurus have found imprints of a proto-feather that looks like the missing link between primitive downy feathers and the modern feathers seen on birds.

    Okay then! All those pro-intelligent design type people arrayed against evolution carp on about the lack of transitional fossils. So when something is found that shows a transitional form of feathers and can lend insight into the evolution of this trait you all cry that it proves nothing. I don't think anybody is claiming that this one fossil is the prototypical "missing link". It is one more piece of the puzzle that shows how feathers and birds probably evolved from dinosaurs. I think it is much more likely that this is a real trait than a freak manifestation of a form of feather. Do you know what the odds are that one mutated dinosaur with this "freak manifestation" died in such a place and way to actually be fossilized and then that fossil survived and was found by humans? It is far more likely that this was a normal transitional form and that many dinosaurs had it so that we would be able to find a fossil millions of years later.

    The Fiery Extinction

    By Posted on 5.21.2008 5 Comments

    What exactly killed the dinosaurs? One of the most popular theories holds that the extinction event was driven by an asteroid collision. Evidence for the theory can be found in a thin layer of iridium in what's known as the K-T boundary, a (similarly thin) layer of sediment in the ground which marks where the surface of the Earth was 65 million years ago. Iridium is common in asteroids and not common on Earth. Its presence in the sediment would indicate an impact and release of the material. What happened next is still a matter of debate.

    Uhhh, yes it would kill aquatic dinos if there was enough smoke to block the sun for an extended period. No sun, no photosynthesis, no marine algae, and then deaths on up the food chain.
