Known from its dentary, Qantassaurus intrepidus Rich and Vickers-Rich, 1999 has been the only dinosaur named from this locality. However, the plethora of vertebrate fossils collected from Flat Rocks suggests that further dinosaurs await discovery.

Saurian Safari a Walk in the Jurassic Park
Dinosaur Safari Junior Introduction: The rules are a simplified variant Of the Saurian Safari rules developed by Chris Peers and originally published by HLBS publishing 2002, this an instructional aid used for the Smithsonian Summer camp program. The rules were developed for grades K – 5 but fun with older age groups. The instructor will act as a Game Master (GM) and will be responsible for preparing the character sheets and setting up the map. This custom version is for a fast moving with minimal book keeping or rolling on charts. Game time recommended for 45 – 60 minutes per scenario. A. Preparation: The GM will have printer character sheets and a six-sided die (D6) and a ten-sided die (D10). Each gamer will need a figure and character sheet. A large vinyl hex map crossed with a river is used for the camp. 1. Setup map. The GM will set up the hex map. Terrain types are forest, river or swamp, clear or hills. Follow guidelines for map set up listed for the scenario. The goal is represent the environment of the period.

A Reassessment of the Phylogenetic Position of Cretaceous Sauropod Dinosaurs from Queensland, Australia
Asociación Paleontológica Argentina. Publicación Especial 7 ISSN 0328-347X VII International Symposium on Mesozoic Terrestrial Ecosystems: 139-144.Buenos Aires, 30-6-2001 A ReasSessmenT of the phylogenetic position of CretaceoUS SaUROPOd dinosaURS from Queensland, Australia Ralph E. MOLNAR1 Abstract. The Cretaceous sauropod material from Queensland, Australia, has been regarded as pertaining to a persistently primitive sauropod lineage (e.g., Coombs and Molnar). The specimens derive from the Toolebuc and Allaru (Albian marine) and Winton (Cenomanian continental) Formations. Recent phyloge- netic analyses carried out by workers in Argentina, the USA and England permit a reassessment of this fragmentary material. As far as can be ascertained from the material, there is no indication from the char- acter states that more than a single taxon is represented. Character states diagnostic of the Titanosauriforrnes, the Titanosauria, the Somphospondyli and the Titanosauridae are present. Thus the Queensland material does not pertain to cetiosaurids but belongs to titanosaurs, extending their range in- to Australia Key words. Sauropods. Austrosaurus. Titanosaurs. Cretaceous.

Most of the abundant sauropod material from the Sao Khua Formation (Early Cretaceous), collected on the Khorat Plateau, in northeastern Thailand, is referable to this species. Phuwiangosaurus is a middle-sized sauropod, which is clearly different from the Jurassic Chinese sauropods (Euhelopodidae). On the basis of a few jaw elements and teeth, P. sirindhornae may be considered as an early representative of the family Nemegtosauridae. Key words : Sauropoda, Osteology, Early Cretaceous, Thailand Description du type et du matériel rapporté de Phuwiangosaurus sirindhornae Martin, Buffetaut et Suteethorn, 1994, un sauropode du Crétacé inférieur de Thaïlande Résumé : Le spécimen type de Phuwiangosaurus sirindhornae est un squelette incomplet, partiellement articulé, découvert dans la région de Phu Wiang (Nord-Est de la Thaïlande). Phuwiangosaurus est un sauropode de taille moyenne (15 à 20 m de longueur) très différent des sauropodes du Jurassique chinois. La majeure partie de l’abondant matériel de sauropodes, récolté sur le Plateau de Khorat (Formation Sao Khua, Crétacé inférieur), est rap - portée à cette espèce. -

Brains and Intelligence
BRAINS AND INTELLIGENCE The EQ or Encephalization Quotient is a simple way of measuring an animal's intelligence. EQ is the ratio of the brain weight of the animal to the brain weight of a "typical" animal of the same body weight. Assuming that smarter animals have larger brains to body ratios than less intelligent ones, this helps determine the relative intelligence of extinct animals. In general, warm-blooded animals (like mammals) have a higher EQ than cold-blooded ones (like reptiles and fish). Birds and mammals have brains that are about 10 times bigger than those of bony fish, amphibians, and reptiles of the same body size. The Least Intelligent Dinosaurs: The primitive dinosaurs belonging to the group sauropodomorpha (which included Massospondylus, Riojasaurus, and others) were among the least intelligent of the dinosaurs, with an EQ of about 0.05 (Hopson, 1980). Smartest Dinosaurs: The Troodontids (like Troödon) were probably the smartest dinosaurs, followed by the dromaeosaurid dinosaurs (the "raptors," which included Dromeosaurus, Velociraptor, Deinonychus, and others) had the highest EQ among the dinosaurs, about 5.8 (Hopson, 1980). The Encephalization Quotient was developed by the psychologist Harry J. Jerison in the 1970's. J. A. Hopson (a paleontologist from the University of Chicago) did further development of the EQ concept using brain casts of many dinosaurs. Hopson found that theropods (especially Troodontids) had higher EQ's than plant-eating dinosaurs. The lowest EQ's belonged to sauropods, ankylosaurs, and stegosaurids. A SECOND BRAIN? It used to be thought that the large sauropods (like Brachiosaurus and Apatosaurus) and the ornithischian Stegosaurus had a second brain. -

Titanosauriform Teeth from the Cretaceous of Japan

Basal titanosauriforms were present in Japan during the Early Cretaceous before Aptian, and there is the possibility that the Brachiosauridae may have been included. Basal titanosauriforms with peg-like teeth were present during the “mid” Cretaceous, while the Titanosauria with peg-like teeth was present during the middle of Late Cretaceous. Recent excavations of Cretaceous sauropods in Asia showed that multiple lineages of sauropods lived throughout the Cretaceous in Asia. Japanese fossil records of sauropods are conformable with this hypothesis. Key words: Sauropod, Titanosauriforms, tooth, Cretaceous, Japan.

A Stable Isotopic Investigation of Resource Partitioning Among Neosauropod Dinosaurs of the Upper Jurassic Morrison Formation
A stable isotopic investigation of resource partitioning among neosauropod dinosaurs of the Upper Jurassic Morrison Formation Benjamin T. Breeden, III SID: 110305422 [email protected] GEOL394H University of Maryland, College Park, Department of Geology 29 April 2011 Advisors: Dr. Thomas R. Holtz1, Jr., Dr. Alan Jay Kaufman1, and Dr. Matthew T. Carrano2 1: University of Maryland, College Park, Department of Geology 2: National Museum of Natural History, Department of Paleobiology ABSTRACT For more than a century, morphological studies have been used to attempt to understand the partitioning of resources in the Morrison Fauna, particularly between members of the two major clades of neosauropod (long-necked, megaherbivorous) dinosaurs: Diplodocidae and Macronaria. While it is generally accepted that most macronarians fed 3-5m above the ground, the feeding habits of diplodocids are somewhat more enigmatic; it is not clear whether diplodocids fed higher or lower than macronarians. While many studies exploring sauropod resource portioning have focused on differences in the morphologies of the two groups, few have utilized geochemical evidence. Stable isotope geochemistry has become an increasingly common and reliable means of investigating paleoecological questions, and due to the resistance of tooth enamel to diagenetic alteration, fossil teeth can provide invaluable paleoecological and behavioral data that would be otherwise unobtainable. Studies in the Ituri Rainforest in the Democratic Republic of the Congo, have shown that stable isotope ratios measured in the teeth of herbivores reflect the heights at which these animals fed in the forest due to isotopic variation in plants with height caused by differences in humidity at the forest floor and the top of the forest exposed to the atmosphere.
