The EditorialBoard of Integrative Zoology should be proud of thegains made since the inaugural issue of March 2006. Thejournal continues to experience impressive growth in theareas of readership and usage. In 2007 subscriptions tothe journal grew by 50%, and full-text article downloadsof journal content increased by 153%. There are nowmore researchers than ever receiving table-of-contentsalerts, with the number of people subscribing to thisservice for Integrative Zoology growing by over 170%last year.展开更多

基金I thank Dr Jessica Reeves,RMIT University,who helped with photography.Mr Ray Osborne,Heritage Victoria,and Mr Chris White,Acting Pro-Vice Chancellor(Group Governance),RMIT University,managed the legal paperwork,making extraction of the fossil both economically and mechanically feasible.This paper was presented orally at the Second International Symposium of Integrative Zoology at the Institute of Zoology,Chinese Academy of Sciences,Beijing,China,on 10 December 2007.
