Eastonian trilobite faunas of the Gordon Group in Tasmania include the new species Ceraurinella oepiki, Erratencrinurus trippi, and Pliomerina trisulcata, as well as a reedocalymeninid probably allied to Sarrabesia Hammann & Leone, 1997. Ceraurinella and Erratencrinurus have not previously been reported from Australia, the former being predominantly Laurentian but also known from NE China, the Himalaya, and Vietnam, and the latter mostly Baltic/Laurentian. Peri-Gondwanan species of Ceraurinella appear to form a clade, within which Tasmanian and Indian (central Himalayan) taxa are closest relatives. 相似文献

A large fossilized crocodilian left femur recovered from the Pliocene Chinchilla Local Fauna of southeastern Queensland, Australia, exhibits a region of proliferative bone, consistent with an episode of osteitis. The nature and location of the pathology suggest a simple fracture with puncture wounds, possibly the result of a crushing bite of another crocodile, followed by infection. The size and morphology of the femur most closely resembles the now extinct Plio-Pleistocene crocodile Pallimnarchus. 相似文献

This note considers Blair, Kaserman, and Romano's conclusion (1989) that the only optimal solution in the case of bilateral monopoly is the joint profit maximization solution and examines the pattern of industrial location under joint profit maximization. 相似文献

The Boyadjian et al dental wash technique provides, in certain contexts, the only chance to analyze and quantify the use of plants by past populations and is therefore an important milestone for the reconstruction of paleodiet. With this paper we present recent investigations and results upon the influence of this method on teeth. A series of six teeth from a three thousand years old Brazilian shellmound (Jabuticabeira II) was examined before and after dental wash. The main focus was documenting the alteration of the surfaces and microstructures. The status of all teeth were documented using macrophotography, optical light microscopy, and atmospheric Secondary Electron Microscopy (aSEM) prior and after applying the dental wash technique. The comparison of pictures taken before and after dental wash showed the different degrees of variation and damage done to the teeth but, also, provided additional information about microstructures, which have not been visible before. Consequently we suggest that dental wash should only be carried out, if absolutely necessary, after dental pathology, dental morphology and microwear studies have been accomplished. 相似文献
