{"title":"Rib remodelling changes with body size in fossil hippopotamuses from Cyprus and Greece","authors":"Justyna J. Miszkiewicz, Athanassios Athanassiou, George A. Lyras, Alexandra A. E. van der Geer","doi":"10.1007/s10914-023-09688-y","DOIUrl":"https://doi.org/10.1007/s10914-023-09688-y","url":null,"abstract":"Abstract Large species that are isolated for thousands of years on islands often evolve extreme degrees of dwarfism. Very little is known about physiological processes that accompany such extreme transitions in extinct dwarf species. We tested whether physiological cycles of bone maintenance (remodelling) in dwarf adult hippopotamuses correlate with insularity-driven body mass shifts that may occur due to variables such as ecological release from predation pressure and change in access to resources. We hypothesised that hippopotamuses with the smallest body size should show higher values of osteocyte lacunae, proxies for osteoblast proliferation during cycles of remodelling, when compared to relatively larger dwarf forms, as well as much larger mainland common hippopotamuses. We examined 20 ribs from three extinct Pleistocene Hippopotamus species spanning a gradient in body size: H. minor (~132 kg, Cyprus), H. creutzburgi (~398 kg, Crete), and H. antiquus (~3200 kg, mainland Greece). Ribs were selected because they reflect bone metabolic rates that are not completely clouded by factors such as biomechanics. Densities of osteocyte lacunae (Ot.Dn) were examined in 864 individual secondary osteons observed in histology sections. We found the highest average Ot.Dn in the H. minor ribs, intermediate Ot.Dn in the H. creutzburgi ribs, and the lowest Ot.Dn in the H. antiquus ribs. It appears that Ot.Dn distinctly separated these three species, possibly signifying a gradient in bone remodelling such that bone tissue optimises maintenance in the face of insularity-driven reduction of body size. We discuss hippopotamus rib bone microstructure and the utility of Ot.Dn in palaeontological analyses for elucidating intricate biological processes occurring in bone of insular fossil mammals.","PeriodicalId":50158,"journal":{"name":"Journal of Mammalian Evolution","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135868627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Konidaris, Thomas Lechner, Panagiotis Kampouridis, Madelaine Böhme","doi":"10.1007/s10914-023-09683-3","DOIUrl":"https://doi.org/10.1007/s10914-023-09683-3","url":null,"abstract":"Abstract During the Miocene, proboscideans reached their greatest diversification, and due to their marked evolutionary changes in dental size and morphology, they comprise an important biostratigraphic/biochronological tool. In this article, we study the proboscideans from the Late Miocene hominid locality Hammerschmiede (Germany), whose fossiliferous layers HAM 6, HAM 4 and HAM 5 are dated to 11.42, 11.44 and 11.62 Ma, respectively. The studied material consists of mandibular, tusk and cheek tooth specimens, which are attributed to the deinothere Deinotherium levius and the tetralophodont gomphothere Tetralophodon longirostris . An almost complete juvenile mandible of D. levius was CT-scanned and revealed that the erupting lower tusks represent the permanent ones. The mandible is most possibly associated with a lower deciduous tusk, and therefore these specimens capture the rare, and short in duration, moment of transition between deciduous and permanent lower tusks in fossil proboscideans and represent the first such example in deinotheres. The chronologically well-constrained proboscidean fauna from Hammerschmiede and the examination of other assemblages from European localities indicate that the coexistence of D. levius and T. longirostris characterizes the late Astaracian–earliest Vallesian, while Hammerschmiede may showcase the transition from the Middle Miocene trilophodont ( Gomphotherium )-dominated faunas of central Europe to the Late Miocene tetralophodont-dominated ones. Finally, in order to decipher the dietary preferences of the Hammerschmiede Tetralophodon we performed dental mesowear angle analysis, which revealed a mixed-feeding diet with an important browsing component, significantly different from the heavily browsing one of Deinotherium known from other localities. Such distinct feeding habits between the taxa indicate niche partitioning, which allowed their sympatry.","PeriodicalId":50158,"journal":{"name":"Journal of Mammalian Evolution","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135061205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
