Herbivorous dinosaur found in the Al-khoudh area. This dinosaur is similar to the Zalmoxes and Rhabdodon dinosaurs. The skeleton in the Bait Al Baranda Museum was assembled from bones borrowed from several museums.

Banded fine-grained pyrite in shale from the Precambrian of Australia. (public display, Leadville Mining Museum, Leadville, Colorado, USA) A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates. The sulfide minerals contain one or more sulfide anions (S-2). The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals. Many sulfides are economically significant, as they occur commonly in ores. The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc. Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size. These minerals will not form in the presence of free oxygen. Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals. Pyrite is a common iron sulfide mineral (FeS2). It’s nickname is “fool's gold”. Pyrite has a metallic luster, brassy gold color (in contrast to the deep rich yellow gold color of true gold - www.flickr.com/photos/jsjgeology/sets/72157651325153769/), dark gray to black streak, is hard (H=6 to 6.5), has no cleavage, and is moderately heavy for its size. It often forms cubic crystals or pyritohedrons (crystals having pentagonal faces). Pyrite is common in many hydrothermal veins, shales, coals, various metamorphic rocks, and massive sulfide deposits. The rock shown above consists of numerous bands of fine-grained pyrite interbedded with dark shale. Published research has shown that the pyrite is diagenetic, formed by sulfate reduction from sulfate-bearing groundwater that moved along bedding planes of the Urquhart Shale host rocks (see Painter et al., 1999). The sulfate source was evaporitic gypsum-anhydrite-barite in the same stratigraphic unit.

This image shows a 2.1 billion year old rock containing black-banded ironstone. The rock weighs about 8.5 tons, and is approximately two meters high, three meters wide, and one meter thick. It was found in North America and belongs to the National Museum of Mineralogy and Geology, Dresden, Germany. The rock is located at +51°2'34.84" +13°45'26.67".

Text Appearing Before Image: This season of 1921 George Sternberg became the first dinosaur col- lector on the Red Deer River to have his work recorded in motion pictures. This happened by a curious error. The Dominion Motion Picture Bureau, predecessor of the National Film Board of Canada, had decided to make a short motion picture based on the work being done by the Geological Survey of Canada in the collecting and displaying of Canadian dinosaurs. The camera party sent to Alberta was naturally supposed to visit the Geological Survey party under Charles M. Sternberg, but local directions sent them to the camp of George Sternberg. So this excellent little film records field work by the University of Alberta party and preparation being done at the National Museum of Canada in Ottawa. That winter George Sternberg continued the preparation of the speci- mens obtained during the two preceding field seasons, but in the spring he resigned to accept a position with the Field Museum of Natural History of Chicago, under Elmer S. Riggs. The summer of 1922 was the last time that the eldest of the Sternberg sons worked on the Red Deer River, his collec- tion going to Chicago. However, he returned to Edmonton for several months in 1935, to complete the preparation of the collection that he brought together in 1920 and 1921. When George Sternberg left the Geological Survey of Canada in 1918, the only one of the four Sternbergs remaining at Ottawa was Charles Mortram Sternberg, the second son of C. H. Sternberg. Actually, Charles had his first independent expedition to the Red Deer badlands in 1917, C. M. Sternberg ami G. E. Lindblad working on the skull of a horned dinosaur (Centrasaurus sp.), Oldman formation, Red Deer River, 1917. N.M.C., No. 39994.
