21、 Australia Photograph and story adapted from .au/wa-news 17th November 2010 Dr Katherine Trinajstic has been awarded one of the prestigious Prime Ministers Prizes for Science for her work investigating and interpreting soft tissues preserved in fossil fish. The Malcolm McIntosh Prize for Physical Sc

22、ientist of the Year (for scientists in the early stages of their careers) carries a cash prize of $50000, which Dr Trinajstic said would be put towards further research and possibly used to encourage young scientists from the Kimberley region of northern Western Australia to develop their careers. D

23、r Trinajstic, who is a Research Fellow at Curtin Universitys School of Science and is also based at the Western Australian Museum in Perth, has been studying Devonian fish fossils from the Gogo Formation in the Canning Basin of the Kimberley Ranges since 1995, in collaboration with Dr John Long (now

24、 of the Los Angeles Natural History Museum). Complete skulls of these 380 million year-old armoured fish are often exquisitely preserved in limestone concretions. The conventional method of studying the fish used dilute acetic acid to dissolve the limestone, leaving just the bony material. Dr Trinaj

25、stics innovative technique, involving the use of synchrotron light and CT scanning to virtually dissect the entombed fossils, enabled her discovery of muscles and internal organs in the Gogo fish. These are now the oldest known fossilised vertebrates with soft tissue. Her interpretation of one speci

26、men as the mother fish, that had an umbilical cord still attached to its embryonic offspring, revealed a vertebrate giving birth to live young some 200 million years earlier than was previously thought. 13 OPINION Brian McGowrans Statement to the International Commission on Stratigraphy, November 20

27、07 On stratigraphy 1. The core, the heart, the essence of geology is to be found in rock relationships and earth history. Stratigraphy is central to the ordination of strata and events and their correlation and age determination. These statements are as true today as they were in the early 19thC whe

28、n (a) the emergence of geology from geognosy was driven by historicism, as Martin Rudwick has made clear, and subsequently (b) Darwins achievement had more to do with his grasp of Earth and life history than with his theory of natural selection, as Michael Ghiselin demonstrated four decades ago. 2.

29、We can look at the state of stratigraphy at two levelsone being the science itself, the other pertaining to education and public culture, especially our pervasively ahistorical mindset. 3. In my opinion the discipline of stratigraphy has never been more vibrant than it is today. Within the exuberant

30、 expansion of the stratigraphic enterprise and toolkit I see four components: one is perceptual, two are major scientific advances and one is in technological advance. The latter is the access to strata afforded by deep-ocean drilling. The scientific advances are cyclostratigraphy/astrochronology an

31、d sequence stratigraphy. The first component is our increasingly ambitious, but increasingly feasible objective of an integrated biohistory and geohistory of the planet embracing its neritic, pelagic and terrestrial environmental realms. 4. Is there life after the last GSSP has been voted in and nai

32、led down? Sequence stratigraphy and cyclostratigraphy/astrochronology are expanding rapidly, and a jolly good thing too. Genetic packages, synthems, third-order cyclesthere are as many allostratigraphic variants as there are environments of deposition. At present sequence stratigraphy is as the elep

33、hant was to the six blind sages of Baluchistanit feels not the same to the siliciclastic sedimentologist in thick molassic wedges as to the palaeoceanographer in delicate carbonate drapes. We have not as yet cracked the problem of glacioeustasy vis-vis tectonoeustasy; but we will. We will extract a

34、cogent sea-level curve from the clattering signals of Earth history. Meanwhile cylostratigraphy, having a smoother run, encourages us to ask questions of the rock record and organic evolution that were but foolish dreams not so long ago. 5. Commissions and committees should encourage and facilitate,

35、 more than control intellectual efflorescence. The International Stratigraphic Guide makes that point. During the Guides gestation the Hedberg triad of lithostratigraphy, biostratigraphy and chronostratigraphy was widely debated. So too was Hedbergs stern admonishing that the frameworks of stratigra

36、phy be kept clear of our perceptions of the nature of the stratigraphic record. But the Vail et al. sequences and the Shackleton et al. root of cyclostratigraphy both emerged virtually coevally with the Guide, and stratigraphy has changed faster and more comprehensively since the Guide appeared than

37、 during the decades of its gestation. 14 6. Brian Harland distinguished the phenomenon category of stratigraphy, meaning the actual science, from the framework category, meaning the rules and regulations, the GSSPs and the votes, the consensual erection of the timescales, and the politics of getting

38、 the golden spike into ones territory. Gradstein made the distinction nicely on the ICS website. The distinction is useful in focusing on this question: how, and why, should the ICS be responding to rapid advances in stratigraphy and to the ongoing cultural variations in our perceptions of the natur

39、e of the stratigraphic record? Where Hedberg advocated what amounted to an agnostic approach (or so I have asserted) over European protests, we should now be engaging with that record and its nature. The next manifestation of the Guide is but one of the nodes here. 7. It is with feelings of bitter i

40、rony that I move from the excitement of modern stratigraphy in biohistory and geohistory to the sense that stratigraphy has never been in worse shape in education and public perception. In a 2006 survey of academia for Geoscience Australia I found that things were even worse than I had feared (with

41、a few honourable exceptions). One was the parlous state of deep-time micropalaeontology. There are quite a few workers in diatoms and palynomorphs, but they toil in environmental problems, meaning the Holocene, perhaps groping down into the gloom of the latest Pleistocene. Macro- and micropalaeontol

42、ogy teaching are mostly in a bad way. More disturbing still is the collapse of stratigraphy in undergraduate coursestaught by caring retirees or taught desultorily or not at all. Probably our graduates are more at home with seismic-stratigraphic image analysis than with dirty-fingernailed analysis o

43、f real strata. The basin geologists grasp their basinal structure more securely than its history. I am told that Australia is not atypical in this situation, nor in the distorting pull of the Recent and sub-Holocene through increased funding for environmental studies in the three environmental realm

44、s. Riding the gloom, I go a step further. Education, science education, and increasingly geoscience eduction are profoundly ahistorical. Structure and process resonate in science, technology and public policy. History, with its prefixes human-, pre-, bio- and geo-, does not. My concern for the futur

45、e health of history and the historical disciplines now matches my passion for the quintessentially historical disciplinesbiostratigraphy and stratigraphy. 15 MEMORIAL NOTICE Obituary Andrew Grebneff: 6 June 1959-7 July 2010 Andrew Grebneff - an exceptional fossil preparator in the Department of Geol

46、ogy at University of Otago - died unexpectedly on 7 July, aged 51, during a private visit to Tiujana, Mexico. Andrew had worked the previous week in the fossil preparation lab until Wednesday 30 June. It took some time to organise return of Andrews body; the NZ Ministry of Foreign Affairs and Trade

47、and the NZ Embassy in Mexico City were most helpful. A funeral was held Monday 26 July in Dunedin, followed by a reception in the Geology Museum, University of Otago. The Museum was the main focus of Andrews career, and includes his former work area and displays of material that he prepared. Andrew

48、had consuming interests in paleontology, and in the study of fossil and living molluscs. Before starting work as a preparator, he did 2 years of study at Otago, with the aim of becoming a paleontologist, but he never graduated. He returned to the Department of Geology, University of Otago, in 1985,

49、to work for me as a fossil preparator on rolling short term contracts mainly to collect and prepare fossil vertebrates. We had some most rewarding and excellent field trips. Around 1990, we had several years of field funding from National Geographic to support the exploration for and recovery of fos

50、sil whales and dolphins. The National Geographic support allowed over a month of field work in some years; we ranged across the South Island, but worked mostly in the Eocene, Oligocene and Miocene rocks of the southern Canterbury Basin around the Waitaki Valley region. That work led, incidentally, t

51、o the development of a field-based major educational and tourist resource, the Vanished World Centre and Trail. Andrew also carried out much field work in the Permian-Jurassic of the Southland Syncline, with Doug Campbell and others. For participating students and overseas visitors - from Australia,

52、 Japan, China, USA, Mexico, Argentina, Britain, France, Denmark and beyond 16 - the field work offered memorably formative experiences. In the field, Andrew was an excellent observer, painstaking preparator, rally driver, witty company, and practical joker - who, strangely, really disliked getting d

53、irty. In the lab, Andrew was an exceptionally skilled and patient preparator, meeting the highest international standards. In 1992, he received the Kingma Award from the Geological Society of New Zealand, in recognition of his skills. The excellent quality of his work is reflected in the exquisite p

54、reparation of fossils such as the cetaceans Waipatia, Llanocetus, Mauicetus, and Australodelphis, the shark Carcharodon angustidens, the extinct moon-fish Megalampris, Palaeeudyptes-like penguins, and many more vertebrates - and a plethora of invertebrates: molluscs, brachiopods, arthropods, echinod

55、erms, corals, bryozoans and more. Andrew prepared fossils that have been displayed widely, including Otago Museum (the Southern Lands gallery fossils), Museum of NZ, Vanished World Visitor Centre in Duntroon, the GNS (Geological and Nuclear Sciences) Dead Precious touring exhibition, Fukui Prefectur

56、al Dinosaur Museum exhibition When whales walked on land, National Museum of Nature and Science - Tokyo, and National Museum of Natural History - Smithsonian Institution. He really helped to put New Zealand on the map for vertebrate paleontology, and his work continues to have an impact through the

57、fossils that are currently the focus of an expanding cluster of vertebrate paleontology postgraduate students at Otago. As a paleontologist and preparator at this Department, and as a field collector, Andrew met and worked with a diversity of scientific visitors, senior students, and museum staff. M

58、any visitors enjoyed sitting with Andrew on the steps of the Geology Museum, having afternoon coffee in the sun. He had an extensive correspondence circle, particularly involving molluscs. He spoke with knowledge and understanding about the personal contributions of paleontologists and molluscan wor

59、kers, and used articles written by many. From about 2000, he finally started to contribute observations to manuscripts led by others; most recently he started to compile faunal lists for exceptional molluscan assemblages of Late Oligocene age, from Hakataramea Valley in South Canterbury, and Waimumu

60、 near Gore. Beyond science, Andrew had a prodigious general knowledge, including motorbikes, cars and especially VW buses. He also had strong dislikes, and could not help but be provoked by mention of, for example, speed cameras, politicians, and rugby fanatics. Andrew was rather a private man, who
