New dinosaur species is a missing link

It's fitting that a place called Ghost Ranch, New Mexico, would yield the discovery of a scary-looking creature. But it's not a ghost - it's a dinosaur.

This dog-sized, ferocious-looking critter is called Daemonosaurus chauliodus, which means something along the lines of  “buck-toothed evil lizard,” says Hans-Dieter Sues, lead author of the published research describing this dinosaur, and curator of vertebrate paleontology at the Smithsonian's National Museum of Natural History.

The illustration above compares the head and neck with a quarter. You can see that it has a short snout and enormous front teeth.

Scientists found the skull and neck of this previously unrecognized dinosaur, and described it in a study in the journal Proceedings of the Royal Society B.

This dinosaur provides a link between what paleontologists consider "early" and "later" dinosaurs. There's a gap in the fossil record between the oldest known dinosaurs, which walked or ran on their hind legs about 230 million years ago in Argentina and Brazil, and other predatory dinosaurs that lived much later. Daemonosaurus chauliodus helps fill in a blank in dinosaur history.

This newly discovered species lived about 205 million years ago, and probably preyed on other dinosaurs and other small animals, Sues said. At that time, what is now the American Southwest was located close to the equator, so it was warm and monsoon-like with heavy seasonal precipitation. This dinosaur was probably active during the day, although its large eyes suggest it could have seen at night as well.

How did it go extinct? It may have fallen victim to an extinction event that occurred about 200 million years ago. As the continents were separating, there was a large zone of volcanic activity. Enormous quantities of lava was released, doing "horrible things to the atmosphere." Most dinosaurs made it through (that is, until an asteroid struck around 65 million years ago), but perhaps not this one.

"It just shows that even here in the United States, there are still many new dinosaurs to be found," Sues said. "People always think we have to go to some remote places, but, right here in northern New Mexico, we can still find new dinosaurs."

    With an undignified name like that its probably wishin it stayed buried. Bucktooth ? Thanks Mr Archaeologist. Next up is Bad Hairasaurus.

    Cesar...still waiting on YOUR answer to those questions.

    I personally don't believe in evolution because I don't have the faith...as far as science is concerned, I only believe what I can see.

      I only believe what I can see as well.
      #1 If I've never been there it doesn't exist...ergo....England is a conspiracy or cartographers.
      #2 If I don't understand how it works then it doesn't...ie...."Magnets? How do they work"?
      #3 Another thing I can't see that doesn't exist...atoms...I know you can see atoms with a microscope but re read #2 if for a full understanding....

    God exists. He created evolution. He doesn't care what you think right now. He set the top spinning, and experiences how it all plays out. He loves you, even though you don't deserve it.

      Did God create evolution 6,000 years ago?

      The bible doesn't say creation took 6,000 years, period. That's a misconception that creationists propogate. Please don't attack a book you've probably never read or understand.

      @common sense,

      You might do some research in the future. There are a number of sources that come up with the 6,000 year estimate based on old Hebrew writings. That doesn't make it proven true, but at least you will know more about what you are talking about.

    I call evolution the cartoon theory...because all its "proofs" seem to consist of drawings and artists renderings.

      And I call the Bible the "fairy-tale" theory. Cause its "proofs" consist of myths and stories borrowed from other religions, in other languages, and translated to other languages still. Written by people who werent even there at the time or several decades later. Its the 'Gospel Truth" though.
      You're right however... no pictures in that book. So it must be right!

      Just because your research of the topic has been limited to cartoons does not mean there isn't other evidence.

    Don't we have enough problems without inventing new dinosaurs? Made JimBob so angry he didn't even read this article.

    Religion and Science compliment each other.
    Both require faith to be believed and both are verified by facts/laws.
    The issue with Religion and Science is that we don't know everything.
    Therefore we can't explain everything.

      How much science can you find in the Bible? Noah's ark? Flat earth? Talking snakes? Are you serious?

      Yet that is exactly what religion tries to do: explain everything.

      God did it.

      At least scientists admit their ignorance and tackle the unknown with such a fervor it impresses those who wish to seek the truth.

      This is the silliest thing I have read in a long time. Science and religion are opposites. Science is based on observation, experimentiation and above all a desire to know the truth. Religion is based on the abandonment of the intellect in favour of believing what makes you feel good.

      You just can't wait to die and be put in a box so the worms can eat you until you are gone. How lovely. What a wonderful life you must lead looking forward to this time. Heaven isn't oo far away. Start believing in something more.

    JaC,
    You can have all the "faith" you want. Dont confuse it with anything other than what it is. Your feeling.
    Personally, your feeling about something doesnt mean a darn thing to me.
    I have a feeling you're going to have a surprise after your final breath....

    See how that works.

    Whatever you choose to believe, you can't help loving the idea that the scientists called it "buck-toothed evil lizard." I suspect I know some people who are descendants of this creature.
