Adults of the late Middle Triassic eosauropterygian Brevicaudosaurus jiyangshanensis from southern China exhibit fang-shaped premaxillary teeth that resemble those of some nothosaurids and are adapted for feeding on large prey. Here, we report a juvenile example of the species, about one-third the length of the adult. The new juvenile shares apomorphies of the adult, like the posteriorly constricted parietal table, broadened humeral mid-diaphysis and short tail. However, its juvenile status is confirmed by unfused contralateral neural arch halves and developing epiphyses of the humerus. The small, smooth, conical premaxillary teeth of the juvenile differ from the ornamented fangs of the adult. The differences in the tooth morphology between the juvenile and adult suggest that this is an example of ontogenetic dietary niche partitioning, a common strategy for reducing intraspecific competition.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"76 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145089574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its global use over the past four centuries, the language roots of zoological taxa remain unknown. The lack of a standardized method for studying the etymology of scientific terms hinders a thorough understanding on the origin of zoological nomenclature. To address these gaps an interdisciplinary method bridging zoology, linguistics, and chronology of ancient texts has been established. All genera names in echinoderms, one of the most speciose animal phyla, were examined. Evidence highlights the leading contribution of the Greek language in zoological nomenclature. For the first time it is shown that zoological nomenclature is rooted in the 2nd millennium BC (Greek Linear B script) with one third of the elements being sourced in Ilias (the Iliad) and Odyssea (the Odyssey), the emblematic Greek epic poems dated in the 1st millennium BC. The study elucidates for first time the Greek 3400-year-old language roots of zoological nomenclature. Most language elements are sourced in poetic, philosophical, historic, and economic rather than biological texts unravelling the dispersal of language elements across remote human-knowledge fields for at least 3400 years. The established method is transferable serving much-needed interdisciplinary research on the language roots and evolution of modern scientific terminology.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"54 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145089576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings quantitatively support and refine the hypothesis of Bae and McCafferty in 1995 revealing that curvature and robustness are functionally linked to tusk adaptations. A principal component analysis of the mandibular tusks and forelegs substantiated the grouping of the three dwelling morphotypes (interstitial, burrowing, and hard-substrate burrowing dwellers). Evolutionary trends based on the current Ephemeroidea phylogeny suggest that interstitial dwellers with flattened bodies might have evolved in the basal lineages of Potamanthidae and Euthyplociidae, whereas burrowing dwellers with cylindrical bodies, such as that in most basal lineages of Polymitarcyidae and Ephemeridae, as well as hard-substrate dwellers, such as Povilla—Ashenopus (Polymitarcyidae) and Cheirogenesia—Palingenia (Palingeniidae), appear to have evolved in parallel, with enhanced burrowing efficiency with the forelegs.

Modern molecular techniques have challenged the dogmatic assumption that speciation represents a simple bifurcating process, revealing complex evolutionary dynamics, such as incomplete lineage sorting and reticulated speciation. The diverse topography of Angola, which includes coastal savannahs and high-elevation grasslands, fosters intricate evolutionary processes across a broad range of faunal taxa. Recent studies on Angolan species, such as Cordylus or Afroedura lizards, have provided evidence for these complex patterns of diversification and introgression between populations from different regions. We investigate these processes by revisiting the Angolan Cordylus to gain a better understanding of their diversity, biogeographical patterns, and the evolutionary forces driving their speciation. To investigate this, we conducted a broad geographical survey and performed a detailed examination of molecular and morphological (both internal and external) data. Our results necessitate the description of a new species from the central highlands, Cordylus cultratus sp. nov., and have identified mito-nuclear discordance, which challenges the taxonomic stability of the Cordylus machadoi group. However, this inconsistency might be explained by incomplete lineage sorting, introgression, and/or taxonomic inflation, thus hindering any taxonomic actions within this group.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"195 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145089577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results strongly support the monophyly of Amebelodontidae but necessitate taxonomic revisions. Notably, we propose a new genus, Saegusaia, for Chinese specimens previously classified as Protanancus, which represent a more basal lineage than true Protanancus found in Africa and South Asia. We identify two monophyletic subfamilies within Amebelodontidae: Platybelodontinae and Amebelodontinae. Megabelodon and Eubelodon, traditionally considered aberrant gomphotheres lacking mandibular tusks, are now placed within the Amebelodontinae based on their cheek teeth similarity to other amebelodontines. Additionally, our re-evaluation suggests that Konobelodon britti may be a junior synonym of Torynobelodon campester, restricted to North America. Eurasian forms attributed to ‘Konobelodon’ are stem elephantoids rather than members of Amebelodontidae. These revised classifications enhance our understanding of Amebelodontidae and other longirostrine elephantiforms, highlighting their importance in the broader context of proboscidean evolution.

This species provides a glimpse at the transition between the earliest sauropodomorphs and the classic ‘prosauropods’. To date, the appendicular anatomy of this taxon has not been described in detail. Therefore, in this contribution we present a detailed description of its appendicular skeleton. As expected from its chronostratigraphic position, the limbs of M. itaquii exhibit a combination of plesiomorphic (e.g. absence of a radial fossa, ossified proximal carpals, iliac acetabular wall not fully open) and derived traits (e.g. metacarpal I inset into the carpus, sub-triangular preacetabular process, straight femur). Phylogenetic analyses support the classification of this taxon, along with two or three other Norian taxa, as members of Unaysauridae, an early radiation of plateosaurian sauropodomorphs. An articulated wrist offers rare insights into this region, confirming that sauropodomorphs (like other dinosaur groups) ancestrally possessed at least nine carpals. This finding enhances our understanding of carpal morphology and evolution within sauropodomorphs. Macrocollum itaquii reveals the presence of a unique third phalanx of manual digit V, raising questions about the confidence we can infer the phalangeal counts of the outermost digits.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"24 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic analyses under both maximum parsimony and Bayesian criteria support the placement of Rastodon within the emydopoid clade Kingoriidae. These findings provide the first evidence of Emydopoidea and Kingoriidae in South America and underscore the limited knowledge of dicynodonts during the Guadalupian, particularly outside southern Africa.
