title: Tribal allocation and biogeographical significance of one of the largest sigmodontine rodent, the extinct Galápagos <i>Megaoryzomys</i> (Cricetidae)

description: One of the largest members of Sigmodontinae, the extinct <i>Megaoryzomys curioi</i> from Santa Cruz Island in the Galápagos Archipelago (Ecuador), is traditionally treated as a representative of Thomasomyini. We contrasted this hypothesis based on a direct study of craniodental material of <i>M. curioi</i>, including a well-preserved skull assessed through CT-scan examination, within a broader sampling of brachydonts sigmodontines. <i>M. curioi</i> lacks or presents a poorly expressed suspensory process of the squamosal bone, while in Thomasomyini this structure is well developed. In the same way, <i>M. curioi</i> does not exhibit the condition in the dorsal aperture of the ectotympanic displayed by the Thomasomyini, and the morphology of the mandible also contrasts with the widespread condition shown by Thomasomyini. Besides, the procingulum of the first lower molar in <i>M. curioi</i> lacks the typical pattern of Thomasomyini composed of two defined conulids. Overall craniodental morphology in <i>M. curioi</i> favours its allocation to the Oryzomyini. This alternative hypothesis resolves two biogeographical issues connected with the target genus: (1) Galápagos Islands were colonised by members of a single sigmodontine tribe (i.e., Oryzomyini) and (2) within the sigmodontine radiation; members of the Oryzomyini were uniquely capable of reaching oceanic islands.

title: A new throscid from mid-Cretaceous Burmese amber (Coleoptera: Elateroidea: Throscidae)

description: Throscidae is a small family belonging to the polyphagan superfamily Elateroidea. Fossil throscids with a large morphological variety have been discovered from Cretaceous and Cenozoic amber deposits. However, only one of them has been reported from the fossil-rich Cretaceous Burmese amber so far. Here we describe and figure the second throscid beetle in mid-Cretaceous Burmese amber (ca. 99 Ma), <i>Trixagosoma guangyuani</i> gen. et sp. nov. The new fossil species has <i>Trixagus</i>-like short mesotarsal grooves and <i>Potergosoma</i>-like prosternum with nonparallel carinae. Our phylogenetic analysis indicates that it represents an early branching lineage of Throscidae. Its short mesotarsal grooves on metaventrite might represent an early evolutionary stage of this structure. http://zoobank.org/urn:lsid:zoobank.org:pub:2793C1A1-EE55-4F96-B3E8-E98D289EB261

title: Ground sloth vertebrae identification through multivariate analysis

description: Extinct sloths (Xenarthra, Folivora) are morphologically diverse, despite some similarities among some Pleistocene genera. Cranial and diagnostic postcranial elements (especially limb bones) are taxonomically informative but the axial postcranial skeleton can prove difficult to classify, as in cases with only vertebral remains or when closely related taxa are found together. Here, 24 linear and angular measurements of presacral axial skeletons from eight genera of Pleistocene ground sloths were analysed through multivariate methods for assigning their vertebrae to a genus and to a position along the vertebral column. Both isolated vertebrae and vertebrae associated with partial and complete skeletons of each genus were included. Principal components and linear discriminant analyses show a high percentage (over 90%) of correct taxonomic reclassification. For the position of vertebrae, the accuracy increased significantly when cervical, thoracic and lumbar regions were separately considered instead of the whole column, misclassifying the position of the vertebrae only by a few positions in most cases. Our database is useful for confidently assigning isolated vertebrae of extinct sloths to a specific genus and position, showing that beyond the apparent homogeneity in the axial postcranial skeleton of ground sloths, quantitative studies allow the evaluation of diversity and variation between groups.

title: <i>Brachypotherium perimense</i> (Perissodactyla, Rhinocerotidae) from the Miocene of Nakhon Ratchasima, Northeastern Thailand, with comments on fossil records of <i>Brachypotherium</i>

description: The cranio-dental and postcranial remains of the Rhinocerotidae collected from the sand pit no. 8 at Nakhon Ratchasima in northeastern Thailand, are described in this study. The remains show cheek teeth that tend to have flattened buccal walls, bucco-lingually broad molariform premolars with short crochet, and brachypodal limb bones, suggesting that these remains belong to genus <i>Brachypotherium</i>. Compared with Afro-Eurasian <i>Brachypotherium</i>, the remains are identified as a South Asian species, <i>Brachypotherium perimense</i>. The result reveals that <i>B. perimense</i> was distributed in Southeast Asia during the Late Miocene. The fossil records of <i>Brachypotherium</i> in Afro-Eurasia show that the genus <i>Brachypotherium</i> was already present in the Indian Subcontinent by the earliest Miocene. This genus then became widely distributed and diversified in Afro-Eurasia during the late Early Miocene and Middle Miocene. Its diversity seems to have decreased before it became extinct by the end of the Miocene, with only the African species, <i>B. lewisi</i>, surviving.

title: Archival data provides insights into the ambiguous track-maker gait from the Lower Jurassic (Sinemurian) Razorback beds, Queensland, Australia: evidence of theropod quadrupedalism?

description: The ichnological and palaeobiological interpretation of the first dinosaur tracks described from the Lower Jurassic (Sinemurian) Razorback beds, anthropogenic ‘fireclay caverns’ of Mount Morgan, Australia, is reviewed. This track sequence of two size categories has been widely accepted as having been formed by a theropod walking in an uncharacteristic quadrupedal stance. However, the morphology of the purported manus impression remained ambiguous due to the poor reproduction quality of the original image data. Here, we present previously unpublished archival photographic and replica material of this track surface. These clearly show the morphological details of the track series that are consistent with registration by two different sized bipedal track-makers. Overall, our findings illustrate that retained archival data can be pivotal in the resolution of palaeoichnological obscurities.

title: Quaternary sigmodontines (Mammalia, Rodentia) from Serra da Bodoquena, Mato Grosso do Sul, Brazil

description: Sigmodontine rodents are extremely diversified in the Neotropics but their fossil record remains generally poorly known, especially in Brazil. Here, we examine the assemblage of sigmodontines from the limestone cave Nossa Senhora Aparecida (21°5ʹ27.89”S 56°34ʹ28.77”W), located in Serra da Bodoquena (Mato Grosso do Sul), a karstic region in southwestern Brazil. We describe cranial and dental fragments and recognise the presence of some new species not previously recorded for the region, as <i>Bibimys</i> sp., <i>Graomys</i> cf. <i>G. chacoensis, Thalpomys lasiotis</i>, and <i>Pseudoryzomys simplex</i>. This fossil assemblage is comparable to others fossil sites in Brazil, such as those from Goiás and Rio Grande do Sul, with the predominance of species from open areas, including grasslands, and some of forested environments from Cerrado landscapes.

title: A revision of the poorly known Pontocaspian gastropod genus <i>Abeskunus</i>, and its Central Paratethyan origin

description: Biodiversity and conservation assessments rise and fall with taxonomic accuracy. An example of a still largely unresolved taxonomy is found in the Gastropoda of the Caspian Sea. The present paper clarifies the taxonomy of the genus <i>Abeskunus</i> and its three species of anomalohaline gastropods endemic to the Caspian Sea. Based on material from Pleistocene, Holocene, and (sub-)recent deposits from Russia, Azerbaijan, and Kazakhstan we discuss species discriminations, synonyms, systematic position, as well as uncertainties regarding the type species. Given the apparent loss of all type material, we designate neotypes for all three species. Despite our efforts to collect and analyse new material and available material housed in museum collections, molecular data, and soft-part anatomy are unavailable precluding a firm systematic classification. Overall shell morphology and protoconch microsculpture are indicative of the family Lithoglyphidae. Comparison with Miocene and Pliocene fossils attributed to the genus <i>Zagrabica</i> suggests it to be a likely ancestor of <i>Abeskunus</i>, tracing back the lineage to the late Miocene Lake Pannon. Although the recent literature lists all three species of <i>Abeskunus</i> among the extant Pontocaspian fauna, two of the three species have never been found living and the third one not since the nineteenth century.

title: Drilling gastropod predation on the lower Miocene gastropod assemblages from Kutch, western India: spatiotemporal implications

description: Unambiguous gastropod drilling predation has been reported in shells of Cretaceous age onwards. Global data suggest that the drilling intensity shows wide spatial variation throughout the Miocene. In order to understand the factors controlling geographic variability in drilling predation, data from many regions are needed. The present study includes detailed analyses of drilling intensity (DI) of predation, its spatial variability, and behavioural stereotypy within the lower Miocene gastropod assemblages of the two formations of Kutch, India. The studied area was positioned at about 17⁰N latitude during the lower Miocene. DIs calculated from 25,766 gastropod specimens in the assemblage, as well as at lower taxon levels, are relatively low for the entire lower Miocene. Prey effectiveness (PE) and Multiple drill holes (MULT) are also low. DI in each formation shows spatial variability which is not related to the number of samples per location and specimen numbers. Temporally, DI increases from the Aquitanian to the Burdigalian, and this rise is statistically significant. Low abundance of the predators and bivalves as a potential prey item are two possible causal factors for the low DI’s observed.
