Museum IDs New Species of Dinosaur

Posted by Hemos on Mon Mar 05, 2007 10:43 AM
from the dinosuars-rock dept.
Uryugen writes "A new dinosaur species was a plant-eater with yard-long horns over its eyebrows, suggesting an evolutionary middle step between older dinosaurs with even larger horns and the small-horned creatures that followed, experts said. The dinosaur's horns, thick as a human arm, are like those of triceratops — which came 10 million years later. However, this animal belonged to a subfamily that usually had bony nubbins a few inches long above their eyes"

[+] First Flying Dinosaurs Had Biplane Structure 144 comments
unchiujar writes to mention a BBC article about the design of the first flying dinosaurs. These possible early ancestors of avians apparently resembled biplanes in many ways, with legs hanging down in a fashion similar to WWI fighters. The researchers who made this discovery use this to argue the 'trees down' model of flight evolution, but the article points out this design may possibly be a failed evolutionary experiment. From the article: "Dr Chatterjee, from Texas Tech University in Lubbock, US, explained that two lines of evidence had led the team to this conclusion. Firstly, the researchers argue, dinosaurs and birds move their legs in a vertical plane, not sideways as the tandem flight pattern requires. Secondly, the feathers on Microraptor's hind legs are asymmetrical; one of the two vanes that extend either side of the shaft is narrower than the other. Aerodynamically, the narrow leading edge of these feathers should face forward in flight, against the direction of airflow. This would have given the flying reptiles lift. "
[+] Global Warming May Have Killed the Dinosaurs 269 comments
The Fun Guy sent in a link to the American Society for Microbiology site, your leading news source for everything between nano and macro. The site is featuring a story about new research into the KT barrier extinction: the period in history where the dinosaurs went extinct, along with a number of other families of species. For a number of years scientists have theorized that an impact on the Yucatan peninsula was responsible for the species crash, but microbiological examination of marine organisms of the time indicate life persisted for another 300,000 years after the 'Chicxulub impact'. The researchers at Princeton who made this discovery theorize that global warming caused by a volcanic eruption in India is a more likely culprit for the world-wide devastation. The article generalizes that there is no 'smoking gun' for this event, and further research is required.
[+] New Dinosaur Species Discovery In Utah Released 108 comments
A new species of dinosaur discovered in Utah's Grand Staircase was only recently released to the public. Dubbed Gryposaurus Monumentensis (derived from a combination of "hook-beaked lizard" and a tip of the hat to the discovery location) scientists estimate this duck-billed dino could have had as many as 800 teeth in his massive mouth. "While the diet is unknown, given the considerable size of the creature, the massive teeth and jaws are thought to have been used to slice up large amounts of tough, fibrous plant material. The teeth may hold important clues the dinosaur's eating habits. The Utah museum plans to study the composition of the dinosaur teeth, which when compared to other plant-eating dinosaurs from the Kaiparowits Formation, will help researchers decipher differences in diet."

    And you guys said it wasn't renewable. See, that's why I like science. They are always finding new species. More oil. More oil. I'm going to go buy a Hummer.

    "Unquestionably, it's an important find," said Peter Dodson, a University of Pennsylvania paleontologist. "It was sort of the grandfather or great-uncle of the really diverse horned dinosaurs that came after it."

    Ryan named the new dinosaur Albertaceratops nesmoi, after the region and Cecil Nesmo, a rancher near Manyberries, Alberta, who has helped fossil hunters.

    The creature was about 20 feet long and lived 78 million years ago.

    The oldest known horned dinosaur in North America is called Zuniceratops. It lived 12 million years before Ryan's find, and also had large horns.

    That makes the newly found creature an intermediate between older forms with large horns and later small-horned relatives, said State of Utah paleontologist Jim Kirkland, who with Douglas Wolfe identified Zuniceratops in New Mexico in 1998. He predicted then that something like Ryan's find would turn up.

    "Lo and behold, evolutionary theory actually works," he said.
    - Lo and behold? We knew that evolution works for a long long time now, but does anyone know whether these remains can be used for DNA sequencing so an evolution map could be setup for such creatures?
    • Please note the difference between evolution and evolutionary theory. Evolution is a process that we know happens - we can observe it in labs. Its a fact. Evolutionary Theory is our current best understanding of the what's, why's, and how's of process by which evolution (the fact) occurs. People can (and often do) dispute evolutionary theory all day long without disputing the fact that evolution itself happens - and that's fine, that's science in progress.

    ...it translated in my head as "Museum Intelligently Designs New Species of Dinosaur".

    I've obviously been getting involved in too many evolution-related debates.

      I am surprised whales don't have horns.

      You too, huh? I feel the same. It's one of the most surprising things I know. It's just baffling. I'm not even sure I believe it -- it just seems so far-fetched.

      Yet amazingly -- it's true! They don't have horns! Unless you glue one or more horns on! Which is very dangerous to you *and* the whale, trust me on that.
