First burrow digging dinosaur species discovered

Maiasaura, another Montana dinosaurFrom Belgian daily Het Laatste Nieuws:

An international scientific team has found the first burrow digging dinosaur species ever, the latest issue of Proceedings B of the British Royal Society says.

The plant eater Oryctodromeus cubicularis, unknown until now, lived some 95 million years ago and took care off its offspring in an underground burrow.

The animal was about two meter long; just the tail was 1.25 meter.

The fossil discovery in the US state of Montana marks a new page on dinosaurs, the team of David Varrichio of Montana State University in Bozeman says.

This newly discovered species is distantly related to iguanodons.

They belong to the hypsilophodonts (see here).

  1. Hi Grant, the picture is Maiasaura, a plant eating, so called duck-billed dinosaur. Though it may look somewhat like a duck, ducks, like all birds, originated in the theropods, another (meat eating) branch of the dinosaurs, during the Jurassic.

    The platypus, like other mammals, had its origins not in dinosaurs, but in mammal-like reptiles from before the age of dinosaurs.


  2. ‘Mummified dino” fossil unearthed in Japan
    Washington, Apr 29 : Researchers at Japan’s Fukui Prefectural Dinosaur Museum have found an ancient rock containing a fossilized dinosaur skin.

    The fossil is believed to contain traces of skin that fossilized before it fully decayed. Scientists say the unusual find is the first of its kind in Japan.

    “It is extremely rare for skin to be preserved as fossil because, unlike bones, skin rots. Research on the fossil could help scientists restore dinosaurs in better detail,” said Yoichi Azuma, assistant director of the museum.

    Palaeontologists originally excavated the rock containing the fossil from a site called the Kitadani Quarry in Katsuyama. The layer was dated to the Early Cretaceous period, around 120 million years ago.

    Within the rock, scientists noticed the skin traces and impression on a 9-inch-square, 2.7-inch-thick plate of fine-grained sandstone. The skin impression covers about 60 percent of the plate’s surface and shows both polygonal and circular scales, each measuring a fraction of an inch.

    Researchers believe the dinosaur that left its mark there probably collapsed and died on a wet surface. Sand covered the carcass before it fossilized.

    Azuma said judging by the scale pattern and the shape of the imprint, it looked like the skin came from the leg of a plant-eating dinosaur, possibly a hadrosaur, an amphibious dinosaur with webbed feet and a duck-like bill.

    “It could be from Fukisaurus, a 15.5-foot-long hadrosaur belonging to the subgroup iguanodontia. This subgroup includes some of the world’s largest known veggie dinosaurs, some of which measured up to 50 feet long and weighed as much as eight tons. While not quite as hefty, the still-large Fukisaurus once roamed Japan. A full skeleton of this dinosaur was excavated near the location where the skin fossil was found,” said Azuma.

    “There is a possibility that clearer fossils of dinosaur skins will be found in the same area,” he added.

    Mark Goodwin, assistant director of the University of California Museum of Paleontology, said “the scale pattern might shed some light on what dinosaur it came from if comparisons could be made with dinosaur skeletons, such as hadrosaurs, from North America that have skin or skin impressions preserved over the bones”.

    “These are often referred to as ‘mummified dinosaurs’,” Discovery News quoted him as saying.

    The dinosaur skin fossil will be on display at the Fukui Prefectural Dinosaur Museum in Katsuyama through May.

  3. 24/05 Belgische dinosaurussen krijgen facelift

    De beroemde collectie iguanodons, een dinosaurussoort, van het Museum voor Natuurwetenschappen in Brussel zal een tijdje niet meer te zien zijn.

    De skeletten van de dinosaurussen krijgen een opknapbeurt, net voor ze verhuizen naar een vernieuwde zaal. Op 27 oktober kan het publiek de immense dieren opnieuw bewonderen.

    De zaal waarin de iguanodons van Bernissart oorspronkelijk stonden, is al sinds 2005 niet meer toegankelijk. De ruimte wordt ingrijpend gerenoveerd en de dino’s verhuisden zolang naar een kleinere zaal. Om nu ook de skeletten zelf een opknapbeurt te geven, zijn de iguanodons al sinds 30 april niet meer te zien voor het grote publiek. Op 27 oktober keren de skeletten terug naar een gloednieuwe Galerij van de Dinosauriërs. “Die is mooier, groter, indrukwekkender dan ooit. In een historische omgeving met moderne toetsen komen de beroemde iguanodons uit de collectie van ons museum en veel andere soortgenoten helemaal tot hun recht”, luidt het.

    Voor de skeletten naar hun vernieuwde galerij terugkeren worden ze helemaal uiteen gehaald. Dat demonteren, de beenderen restaureren en alles opnieuw installeren is een monnikenwerk dat zes maanden in beslag neemt. De rest van het Museum voor Natuurwetenschappen blijft open en hanteert een speciaal tarief van 2 euro voor iedereen. Van 3 september tot en met 26 oktober sluit het volledige museum de deuren om nog verdere renovatiewerken uit te voeren.
