Quantifying scientific significance of a fossil site: the Gogo Fossil sites (Late Devonian, Western Australia) as a case study. Memoirs of Museum Victoria 74: 5–15. Assessing the scientific significance of fossil sites has up to now been largely a matter of subjective opinion with few or no metrics being employed. By applying similar metrics used for assessing academic performance, both qualitative and quantitative, to fossil sites we gain a real indication of their significance that enables direct comparison with other sites both nationally and globally. Indices suggested are those using total pages published for both peer-reviewed and combined peer-reviewed and popular publications, total citations from the papers, total impact points for site (citing palaeontologyrelated papers only), total number of very high impact papers (VHIP; journal impact factor>30) and social media metrics. These provide a measure of how much the published fossil data from a site has been utilised. The Late Devonian fossils of the Gogo Formation of Western Australia are here used as an example of how these metrics can be applied. The Gogo sites for example, have produced c.4384 pages of peer-reviewed papers (c.5458 total combined with popular works); generated papers with a total impact point score of 611, including 10 VHI papers, and generated 4009 citations. The sites have an overall h-index of 33. Combing these into a Scientific Site Significance Index (SSSI) will permit direct comparisons of site significance to be made for initiating discussions about site protection, tourism, geopark status, local heritage listings or potential future world heritage nominations.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"12 1","pages":"5-15"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87982293","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}

Dental dimensions suggest it may have weighed at least twice as much as the living Tasmanian devil (Sarcophilus harrisii). Although known only from a lower molar, it exhibits a plethora of carnivorous adaptations including a hypertrophied protoconid, tiny metaconid and a battery of vertical carnassial blades between most of the major cusps, most of which incorporate carnassial notches to immobilise materials being sheared. It is unique among dasyuromorphians in having a massive entoconid that closes the entire lingual side of the talonid. Comparison with previously known thylacinid and dasyurid hypercarnivores suggests its relationships are closer to dasyurids than thylacinids in the main because of the very large entoconid, a cusp that is relatively small to absent in all known thylacinids but commonly small to large in dasyurids. However, the extent of enlargement of the entoconid suggests that it is not closely related to previously known Cenozoic hypercarnivorous dasyurids in the genera Dasyurus, Glaucodon, Sarcophilus or any of the other previously described Cenozoic dasyurids. Although the early late Miocene Ganbulanyi djadjinguli is only known from an upper molar, the reduced area of its protocone suggests a correspondingly reduced rather than hypertrophied entoconid in its as-yet-unknown lower molars. Reconsideration of the structure of the talonid in species of Sarcophilus even suggests that within that Quaternary lineage, the entoconid may have been entirely lost, with the posteriorly displaced metaconid taking its functional place as an occlusal counterpart for the blades of the protocone. The large size of the new species signals the earliest indication within the dasyurid radiation of a late Cenozoic trend towards gigantism that became evident in many lineages of Australian marsupials. While the age is uncertain, on the basis of associated taxa such as species of Ekaltadeta, it is probably either mid or late Miocene in age. Geological features of the deposit suggest it was formed within a pool in a cave environment that periodically underwent desiccation. Some grains suggest an aeolian as well as an alluvial and pluvial origin for the deposit. This may relate to current understanding about environmental change that took place in the region following the mid Miocene climate oscillation.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"1 1","pages":"137-150"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89252115","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}

Morphological variation of stratigraphically important species in the genus Pilosisporites Delcourt & Sprumont, 1955 in the Gippsland Basin, southeastern Australia. Memoirs of Museum Victoria 74: 81–91. Three hundred and ninety eight mudstone samples of Early Cretaceous age from the onshore part of the Gippsland Basin in southeastern Australia were used to ascertain the morphological variation in three species of spores in the genus Pilosisporites. In Australia all species of Pilosisporites are biostratigraphically useful and this study confirms that in the Gippsland Basin the ranges of Pilosisporites notensis, Pilosisporites parvispinosus and Pilosisporites grandis are as defined by some previous authors. Morphological variations of these three taxa from the published descriptions are discussed. In the case of P. grandis and P. parvispinosus the main variation was in the size of specimens, however P. notensis showed sculpture variations in regard to element size, type and distribution. Two distinct types of this species were defined with only one occurring in the youngest part of the section. Modern fern species can exhibit similar spore sculpture and size variations as a result of polyploidy. This could possibly be the cause of the variations in all three species of Pilosisporites and also their short-lived, in geological terms, species ranges.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"51 1","pages":"81-91"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89283854","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}

Warburton, M. Archer, S. Hand, K. Aplin","doi":"10.24199/J.MMV.2016.74.14","DOIUrl":"https://doi.org/10.24199/J.MMV.2016.74.14","url":null,"abstract":"We present the first detailed descriptions of postcranial elements of the fossil marsupial mole Naraboryctes philcreaseri (Marsupialia: Notoryctemorphia), from early Miocene freshwater limestone deposits in the Riversleigh World Heritage Area, northwestern Queensland. Qualitative functional analysis of these elements suggest that Na. philcreaseri was very well-adapted for burrowing, albeit somewhat less so than the living marsupial moles Notoryctes typhlops and N. caurinus. Quadratic discriminant analysis of limb measurements suggests that Na. philcreaseri was subterranean, and its Index of Fossorial Ability is almost identical to that of Notoryctes species, being among the highest known for any mammal. These results suggest that notoryctemorphians evolved their specialised, “mole-like” subterranean lifestyle prior to the early Miocene. Given that forested environments predominated in Australia until the middle-late Miocene, this transition to subterranean behaviour may have occurred via burrowing in forest floors, in which case fossorial mammals that live in tropical rainforests today (such as the placental golden moles Chrysospalax trevelyani and Huetia leucorhina) may represent reasonable living analogues for early notoryctemorphians. However, alternative scenarios, such as a cave-dwelling or semi-aquatic ancestry, should be considered. Phylogenetic analysis using a Bayesian total evidence dating approach places Naraboryctes as sister to Notoryctes with strong support (Bayesian posterior probability = 0.91), and indicates that Naraboryctes and Notoryctes diverged 30.3 MYA (95% HPD: 17.7-46.3 MYA). The age and known morphology of Na. philcreaseri does not preclude its being ancestral to Notoryctes. Using estimates of divergence times and ratios of nonsynonymous to synonymous substitutions per site, we infer that the nuclear gene “Retinol-binding protein 3, interstitial” (RBP3), which plays a key role in vision, became inactive in the Notoryctes lineage ~5.4 MYA (95% HPD: 4.5-6.3 MYA). This is much younger than previous published estimates, and postdates considerably the age of Na. philcreaseri, implying that RBP3 was active in this fossil taxon; hence, Na. philcreaseri may have retained a functional visual system. Our estimate for the inactivation of RBP3 in the Notoryctes lineage coincides with palaeobotanical evidence for a major increase in the abundance of grasses in Australia, which may indicate the appearance of more open environments, and hence selection pressure on notoryctemorphians to spend less time on the surface, leading to relaxed selection on RBP3. Ultimately, however, a fuller understanding of the origin and evolution of notoryctemorphians-including when and why they became “mole-like”-will require improvements in the Palaeogene fossil record of mammals in Australia","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"54 1","pages":"151-171"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81319219","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: 403–408. Frogs have the least understood fossil record of all major vertebrate groups in Australia. Here we report on pelvic remains of three Pleistocene frog species from the Nullarbor Plain, a large region of Australia where no living or fossil frogs had previously been discovered. One ilium, characterised by a small acetabular fossa with an indistinct peripheral rim, a broad dorsal prominence and enlarged supra-acetabular zone, is recognised here as representative of a new species of hylid, Litoria lundeliusi sp. nov. Three other ilia bear the hallmark generic attributes of the small myobatrachid Pseudophryne, two species of which co-occur today over much of southwestern Australia. A second larger myobatrachid is the best represented of the three species, and its ilial morphology matches that of the extant Neobatrachus sudelli. All three species were present in the early Pleistocene, but only N. sudelli is recorded in the middle Pleistocene. The loss of Litoria and Pseudophryne would be consistent with the disappearance of significant bodies of free water from the region, but the cause of the apparent extirpation of N. sudelli, which inhabits arid parts of Australia today, remains a mystery.","PeriodicalId":53647,"journal":{"name":"Memoirs of Museum Victoria","volume":"113 1","pages":"403-408"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76804898","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}
