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."

    My point is this... If you believe Christianity is some made up story and nothing else, why are you so concerned with disproving it. Why is it that Christianity is always under attack? You become so upset when someone makes a comment about Christianity. Why not ignore it and read what you want? Because there is something more to it. Again this is one man's opinion. I do not know you but I wish you well.

      This article doesn't mention any religion at any time. As for religious views, there are many religions way older than judeo-christianity. There are also more populous religions around the planet right now with way different creation beliefs.

      “...why don’t you just ignore Christianity, instead of trying to disprove it?” Please pardon my paraphrasing, Luke. I hope I’ve captured your point, though. One quick answer from my own experience is that my children's’ high school biology teacher is afraid to teach or even mention evolution because she gets complaints from parents and her job is threatened. This is in a public high school in Florida. My kids _love_ archeology, and missing the two-week section on evolution because the teacher was afraid to teach it was a real setback. What are they to do?

      @ Mark... Agree, it's sad when teachers aren't allowed to teach. Not much different than the dark ages when all knowledge that "may" have disagreed with the church's teachings was abolished and punished by death. We have to give our children a choice and a glimpse of all the information that is out there. Then they can choose their own path.

      @Mark – My suggestion is that you as the parent teach your children whatever you believe is right for them to know. Don't rely on public education (paid for or not) to provide your children with what you deem as necessary education. It's ultimately your job as a parent to teach your kid. If you don't have the time because of work or other commitments, hire a tutor to do it for you (aka a teacher that can be controlled by you on what to teach).

      Mr. Luke, thumb up for you, buddy! I like how you make your reply. I remember one of the guys here in the States trying to criticize me for having my bible in hand. I then asked him why he targeted the bible instead of other things I had. He responded and said, "because the bible is sensitive." I giggled and replied with joy, I am happy that there is sensitivity-power and truth in the bible. Anyhow, there will be a day when the truth will prevail.

      Why, Luke, you have it backwards. Christianity isn't always under attack, Christianity is always on the attack and the rest of us are tired of you trying to impose your beliefs on us. We don't care what you believe in your own homes and lives, but we do care when you try to pass laws that prohibit our children from being taught about science in school, or when you try to pass laws to prohibit us from making informed medical choices about our own bodies, or when you try to pass laws telling gay couples that they have no right to love each other. If you believed those things, but didn't try to impose them on us through the force of our secular government, then we wouldn't care. But you do try to impose your beliefs on our lives, so it's quite natural that we push back against that. This article is a perfect case in point. This is not an attack on Christianity, it's a science article about an interesting development in a field that rational people understand to be true, but you guys just couldn't leave it alone. You had to fill the comments with your pro-religious nonsense. So don't complain about how we're attacking you when you stick your religion into the secular aspects of our lives. Next time you see an article about something that happened over 6,000 years ago, just pass it by and no one will attack you for it.

    "Missing link" just seems like pandering to the jury’s-still-out-on-evolution crowd. I wish you’d replace it with the more descriptive “transitional.” And "New dinosaur,” isn’t that an oxymoron?

      There was civilization way before the Jews and their bible. They say the earth is 6,000 years old, but we have written records from other cultures that old. The torah was written 2,500 years ago. Understand the history of what you believe, before you believe in whatever.

      The eye is the easiest organ in the body to track it's stepwise evolutionary development. From single cellled organisms that had light sensitive proteins, to compound eyes with the "retina" broken into individual segments, each with it's own neuron, to the complex eyes we see in vertebrates, where the retina is one contiguous sheet.

      Scroll down a page or two for great answers on "missing link". As they stated, the true authors probably never even wrote that. News has to sell, so headlines are always sensationalized. As far as transitional, there are many examples. Once again scroll down and read from people way more informed than I.

      The believers argue that in order for something to exist something must have created it. Then they say that God exists and nothing created God. Hypocrisy has replaced logic.

      I agree. I write this at about 350 comments and counting. Why is it that so many people feel obligated to rant and rave about evolution and religion just because they see an article about a fossil? All this article is saying is this - Some scientists found a fossil - It was dated at 205 million years ago - that fact is a new discovery, and it's cool and interesting. That's it. And for all of you people who insist that the Earth is only 6000 years old–go find a paleontologist, ask him to show the largest fossil he has available, then have him knock you in the head with it as hard as he can. There's your frickin' evidence moron! Carbon dating is not a conspiracy.

      It wouldn't be a problem if creationists weren't trying to get legislation passed forcing their silly backwards beliefs back into public schools. There was the House Bill 368 (HB 368) in Tennessee as well as a duplicate one in the Senate, SB 1854 in Florida, and the Texan HB 2454 is funny because Texas has no problem with discrimination based on orientation, but a big problem with creationists not being appointed in universities.

      I tend to complain when I see legislation being pushed by creationists who try to get their non-science taught as science.

      Ha – agreed. And I agree with Dr. Grant as well ;-). I'm a Christian (although I refuse to attend a church – make of that what you will, I consider it good sense while others consider it blasphemy) and I see absolutely no reason that God and science can't complement one another. Science is the layman's way of understanding God's laws in the Universe. Science is but the way that we understand the way the universe works. It's not blasphemy, it doesn't disprove God. I love paleontology. Anyone who says dinosaurs are a conspiracy theory needs to tighten their tinfoil hat and get back on the street corner with their sign.

    As usual the creationists refuse to see the evidence that is plain as day. They continue to push the mythical creation stories that unlike evolution have absolutely NO EVIDENCE WHATSOEVER to back them up other than,"the bible says so". I LAUGH AND SPIT at such fallacies.

      Creationists and people who believe in evolution both have evidence, they just interpret it differently biased on their presuppositions about how the world came to be... Both sides have educated people who believe in each theory.
      I personally think its plan as day that there had to be a Creator for life and the plants and solar system to exist. our bodies are so complex, they did not com from a puddle of mud... But if im wrong, it why would it matter? What are the consequences for your beliefs if you are right or if you were wrong?

      You're right, we both have evidence, and both interpret it differently... however...
      "Detecting genetic drift versus selection in human evolution"

      Papers like that are what scientist evidence are. That's what we interpret as "evidence". Creationists provide... well... either Behe (See: Dover Trial Day 11 PM Session) or "the bible"... I generally tend to side with the far more robust source of information.

      You should ask an evolutionary biologist, but if your default answer for everything is "there's a question you cannot yet adequately answer to my full expectations, thus everything you say is wrong and god did it all!", you're really not asking anything from a very honest place, now are you?
