Morphological comparisons of metacarpal I for Australovenator wintonensis and Rapator ornitholestoides: implications for their taxonomic relationships

WHITE, M.A., FALKINGHAM, P.L., COOK, A.G., HOCKNULL, S.A. & ELLIOTT, D.A., 2013. Morphological comparisons of metacarpal I for Australovenator wintonensis and Rapator ornitholestoides: implications for their taxonomic relationships. Alcheringa 37, 1 - 7. ISSN 0311-5518.

Various comparisons of left metacarpal I of the Australovenator wintonensis holotype have been made with Rapator ornitholestoides. These specimens were identified as being morphologically more similar than either was to that of the neovenatorid Megaraptor namunhuaiquii. Owing to the poor preservation of A. wintonensis and R. ornitholestoides, distinct morphological separation between the two appeared minimal. The recent discovery of a near perfectly preserved right metacarpal I of A. wintonensis enables a direct and accurate comparison with R. ornitholestoides. Distinct morphological differences exist between the metacarpals of the two species. A re-evaluation of the age of the A. wintonensis holotype site (AODL 85 ‘Matilda Site’) with zircon dating reveals a maximum age of 95 Ma, 10 Ma younger than the Griman Creek Formation at Lightning Ridge, from which R. ornitholestoides was recovered. This age difference detracts from the probability that the specimens belong to the same genus.

Celebrating British multiculturalism,lamenting England/Britain's past

Drawing upon Littler and Naidoo's ‘white past, multicultural present’ alignment, this article examines English newspaper coverage of two ‘British’ events held in 2012 (the Diamond Jubilee and the London Olympic Games). In light of recent work on English nationalism, national identity and multiculturalism, this article argues that representations of Britain oscillated between lamentations for an English/British past – marred by decline – and a present that, while being portrayed as both confident and progressive, was beset by latent anxieties. In doing so, ‘past’ reflections of England/Britain were presented as a ‘safe’ and legitimate source of belonging that had subsequently been lost and undermined amidst the diversity of the ‘present’. As a result, feelings of discontent, anxiety and nostalgia were dialectically constructed alongside ‘traditional’ understandings of England/Britain. Indeed, this draws attention to the ways in which particular ‘versions’ of the past are engaged with and the impact that this can have on discussions related to multiculturalism and the multiethnic history of England/Britain.
