Muttaburrasaurus The plants, animals and climate of the Australian continent have changed dramatically over long periods of time. Imagine this giant creature roaming the luxuriant wet forests that covered parts of the continent in the Cretaceous period, about 100-110 million years ago. The Muttaburrasaurus ambled along on all four legs or stood on its hind legs. Its large teeth were well adapted to eat tough vegetation such as the leathery foliage of the evergreen forests of Araucaria trees, ancient relatives of the bunya pine of south-eastern Queensland. In 1963, grazier Doug Langdon discovered the fossilised bones of a dinosaur on his property near Muttaburra in central-west Queensland. It was one of the most complete dinosaur skeletons found in Australia. The bones belonged to a new species of ornithopod and palaeontologists named it Muttaburrasaurus langdoni.

Montanoceratops cerorhynchus (Brown & Schlaikjer, 1942) - fossil ceratopsian dinosaur skeleton from the Cretaceous of Montana, USA. (MOR 542, Museum of the Rockies, Bozeman, Montana, USA) The species name is sometimes incorrectly spelled "cerorhynchos". The original publication spells it "cerorhynchus". The genus name is sometimes incorrectly spelled "Montanaceratops". Ceratopsians are the "horned dinosaurs". They were large, quadrupedal, herbivorous dinosaurs having a beaked skull and a frill - an extension of bone behind the skull that partially covered the neck. Ceratopsian dinosaurs are known from the Jurassic and Cretaceous. The last members of the group died out at the Cretaceous-Tertiary boundary, 65 million years ago. This is a partial skeleton of a juvenile Montanoceratops, a ceratopsian from the near-latest Cretaceous of western North America. This type of ceratopsian lacked facial horns. From exhibit signage: Sixty-eight million years ago, when the horned dinosaurs Triceratops and Torosaurus inhabited the coastal plain near the inland ocean, primitive "horned" dinosaurs named Montanoceratops lived in uplands near the young Rocky Mountains. These little protoceratopsians fed on plants with slicing teeth and narrow beaks similar to their giant three-horned relatives. Classification: Animalia, Chordata, Vertebrata, Reptilia, Archosauria, Dinosauria, Ornithischia, Marginocephalia, Ceratopsia, Leptoceratopsidae Stratigraphy: St. Mary River Formation, Maastrichtian Stage, Upper Cretaceous Locality: Little Rocky Coulee, north of the town of Cut Bank, eastern Glacier County, northwestern Montana, USA Info. at: en.wikipedia.org/wiki/Montanoceratops
