Cenozoic dinosaurs in South America – revisited. Memoirs of Museum Victoria 74: 363–377. Of course there were Cenozoic dinosaurs (theropods) in South America, phorusrhacid (‘terror’) birds among others, but that is not the subject here. Why did anyone think there were Cenozoic (non-avian) theropods in South America? Because of a misinterpretation of Ameghino’s belief that derived mammals lived along with dinosaurs in Late Cretaceous Argentina. But also because isolated theropod teeth were found associated with derived (Eocene) mammal fossils. These turned out to be the teeth of Sebecus icaeorhinus. This is a small crocodylomorph, skull length c. 450 mm. More recently discovered sebecosuchians were substantially larger: Barinasuchus arveloi had an (estimated) skull length of c. 1000 mm, similar to that of Daspletosaurus (1000 mm). These crocodylomorphs are generally believed to have been terrestrial animals, presumably preying on large mammals. Thus, although there were no large non-avian theropods in Cenozoic South America, there were crocodylomorphs that seem to have been ecological vicars of large theropods. The reconstruction of terrestrial trophic networks for large terrestrial tetrapods after the Cretaceous-Paleogene extinctions seems to have been slower than often supposed. At (or near) the Cretaceous-Paleogene boundary, large herbivores turned over from archosaurs to mammals, but turnover of large carnivores was slower. In South America, dinosaur-size crocodylomorphs lived as late as the Miocene. Thus modern terrestrial ecosystems do not, trophically, reflect those of even the Early Neogene in some southern continents. Sebecosuchians, at least in South America, seem to have been unaffected by the Cretaceous-Paleogene extinctions.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"1 1","pages":"363-377"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83059228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Memoirs of Museum Victoria 74: 63–71. Lower Cretaceous (Aptian-Albian) rocks of Victoria, Australia are well known for their dinosaur body fossils, but not so much for their trace fossils. For example, the first known dinosaur track from the Eumeralla Formation (Albian) of Knowledge Creek, Victoria, was not discovered until 1980. This specimen, along with two more Eumeralla tracks found at Skenes Creek in 1989, constituted all of the dinosaur tracks recognised in Lower Cretaceous strata of southern Australia until the late 2000s. Unfortunately, none of these first-known dinosaur tracks of Victoria were properly described and diagnosed. Hence, the main purpose of this study is to document these trace fossils more thoroughly. Remarkably, the Knowledge Creek and one of the Skenes Creek tracks are nearly identical in size and form; both tracks are attributed to small ornithopods. Although poorly expressed, the second probable track from Skenes Creek provides a search image for less obvious dinosaur tracks in Lower Cretaceous strata of Victoria. The Skenes Creek tracks were also likely from the same trackway, and thus may represent the first discovered dinosaur trackway from Victoria. These tracks are the first confirmed ornithopod tracks for Victoria, augmenting abundant body fossil evidence of small ornithopods (‘hypsilophodontids’) in formerly polar environments during the Early Cretaceous.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"114 1","pages":"63-71"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87397531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

McLennan (‘Mallee Bird’) and his Aboriginal informant Jowley: The source of early records of the Night Parrot Pezoporus occidentalis in Victoria? Memoirs of Museum Victoria 73: 107–115. Historical records of the Night Parrot Pezoporus occidentalis in north-western Victoria have not always been accepted as valid despite prominent contemporary ornithologists accepting them. We present new supporting information gleaned from newspaper articles written under the pseudonym ‘Mallee Bird’ published in national and local newspapers in the early 20th century. ‘Mallee Bird’ was Charles H. McLennan, a bushman and well-regarded ornithologist who worked on pastoral runs established among the terminal lakes of the Wimmera River in the Big Desert of north-western Victoria. We also provide biographical details of a local Aboriginal man, Jowley, identified by McLennan as his informant about the nest site and clutch size of the Night Parrot. We provide evidence that McLennan and Jowley were known to each other and probably worked together on cattle runs in the Hopetoun–Pine Plains region around the turn of the 19th–20th century. McLennan and Jowley’s observations of Night Parrot calls, habitat use, breeding and flight are some of the earliest published natural history of this most mysterious of Australian birds. They mostly corroborate other contemporary accounts and concur with preliminary findings of current research on the species in south-west Queensland. The relationship between McLennan and Jowley is one of the few documented Victorian examples of aboriginal information being incorporated into European ornithological knowledge. McLennan’s support and encouragement of ornithological expeditions to the Wonga Lake–Pine Plains area was pivotal in having the area declared the first National Park in the Murray Mallee region.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"313 1","pages":"107-115"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72977899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
