We report the first insights into this <em>Stegodon</em>'s bone histology, which furthers our understanding of this species’ palaeobiology, and evaluate the micro-anatomy and metabolic microstructural products retained in well-preserved rib bone tissue. A proximal rib fragment selected from a larger assemblage was sampled at three anatomical regions from which histological sections were produced. The sampling regions differed in cortical width size ranging from relatively thick to thin (17.94mm to 6.31mm). Bone tissue arrangement and histomorphometric variables measuring histological products of adult bone remodelling processes (secondary osteon population density and area, bone area, and Haversian canal percentage) were examined. The preservation of bone histology was very good, showing widespread Haversian bone with indication of several generations of remodelling processes, multiple resorption cavities, and the presence of ‘super’ (unusually large) osteons. Secondary osteon density and geometry varied with cortical width through the serial sections whereby the section with the narrowest cortex produced the highest secondary osteon density but also the largest osteon area. The effects of medullary cavity infilling on the endocortical region in the <em>Stegodon</em> rib may also relate to the adjacent periocortical region. The rib histology of this intermediate-sized dwarfed species shows, for the first time, a degree of secondary bone active remodelling in a <em>Stegodon</em> that indicates this was possibly a long-lived individual. Microscopic bone characteristics shared with other extinct and extant proboscideans may be useful in identifying <em>Stegodon</em> from fragmented mixed fossil assemblages.</div></div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":"109 4","pages":"Article 102654"},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140585541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the terrestrial vertebrate fossil record of the island is still poorly known. A new fossil-bearing paleochannel deposit was discovered in La Union Province, northwestern Luzon, Philippines. This paleochannel is inferred to be of Pleistocene age and has yielded fossils tentatively classified as a bovid (<span><em>Bubalus</em></span> sp.), a cervid (<span><em>Rusa</em></span> sp.), a suid (<em>Sus</em><span> sp.), and a large crocodile (Crocodylidae). Interestingly, a proximal fragment of the left tibia of a cervid shows multiple bite marks. This study analyzes the bite marks and modifications on the specimen to infer its possible trace maker and explore its implications in understanding the ancient predatory guild of Luzon. Three sets of modifications were recognized on the specimen, namely the bite marks, the broken proximal end and the dry bone fractures. A crocodilian agent for the bite marks is supported by the bisections, their occurrence in the paleofaunal assemblage and the fluvial setting of the deposit. However, an unknown carnivoran agent interpretation cannot be fully disregarded given the ambiguity of bisected marks and the possibly gnawed proximal end of the specimen. Unfortunately, given the lack of in situ context and apparent overprinting, the extent of the peri- and post-mortem modification remains uncertain which hinders the identification of the predatory agent. Verification of the observations reported in this study would require the systematic collection and detailed taphonomic analysis of additional fossil specimens from the deposit.</span></div></div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":"109 4","pages":"Article 102649"},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140585574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studied ostracod assemblage includes thirty-one species and subspecies, belonging to twenty-three genera and seventeen families. The ostracod group belonging to Cytheroidea Baird, 1850 represents the most abundant group that reaches 81.99% in Munqar El-Shinnara section, 81.88% in Sath El Hadid section, and 61.12% in Elwe El Breig section.

These analyses are applied on a matrix consists of some nominated Middle Eocene species from 13 countries. The results point to two distinctive provinces, Southern Tethys Province (Algeria, Tunisia, Libya, Egypt and Jordan) and the Northern Tethys Province (England, Germany, Spain, France, Belgium, Ukraine, Hungary and Turkey).

The work carried out to verify this hypothesis used a number of tools, including palaeontology, the results of which seem to us to have been greatly embellished given the paucity of reliable data available. Indeed, it is clear that the hypothesis concerns a geographical area that is largely inaccessible today, located at a depth of 120 meters in the South China Sea, and that the faunal assemblages taken into account remain imperfectly defined to allow such a hypothesis to be tested. We provide a summary of the main work carried out to date and a critical assessment of the articles published over the last few decades. It emerges that the fossil series considered (essentially mammals) are neither well chronologically set nor well defined from a taphonomic point of view, notably because they are based on unsatisfactory references, which are themselves poorly dated or based on mixtures of different faunas. These shortcomings also call into question the renewed and attractive hypothesis of the flexibility of the diet and change of habitat (ecological niche) of certain taxa, based on isotopic analyses, as recently proposed. We advocate the implementation of systematic fine excavations that take into account the taphonomy of the sites, but also show that progress has been made to go further.</div></div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":"109 4","pages":"Article 102657"},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140585467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
