“…The Pliocene leporine lagomorph Hypolagus (extinct) and Oryctolagus were surely smaller compared to the larger rodents before mentioned, but still robust forms compared to the extant species, like Oryctolagus laynensis (López Martínez, 1977) (see López-Martínez, 1989;Lopez-Martinez, 2008). They were recorded in the late Early and Late Pliocene of western Europe, also in the Roussillon basin (Mein and Aymar, 1984) together with Trischizolagus (Radulesco and Samson, 1967) (another leporine lagomorph). Eucyon davisi apparently fed on smaller prey, since the estimated prey size is around 2 kg (Bartolini-Lucenti and Rook, 2021).…”

IntroductionThe phylogenetic and ecological importance of paranasal sinuses in carnivorans was highlighted by several previous authors, mostly in extant species. Nevertheless, no specific study on this feature on extant canids, and no one on fossil representatives of the family, has been published up to now. Here, we analyze for the first time the paranasal sinus of extant and fossil canids through computed tomographic techniques to characterize them morphologically and morphometrically, making ecological inferences.MethodsTo do so, we applied for the first time an innovative deformation-based morphometric approach.ResultsThe results obtained for extant species highlight a remarkable correlation between morphology and ecomorphotypes previously defined by some scholars (namely hypercarnivorous group-hunters; small-prey hypercarnivores, mesocarnivores, hypocarnivores). Our results thus support the direct relationship between diet preferences and the development of frontal sinus in canids. Regarding fossil specimens, we reconstructed for the first time the frontal sinus of three Eucyon species and compared it to those of living forms.DiscussionThe best-preserved specimen, the only known cranium of Eucyon adoxus dated to the Late Pliocene of Saint-Estève (France), displayed similarities with hypercarnivorous group-hunter canids by the large sinus prominences. Given that the overall craniodental morphology of E. adoxus suggests that it acted as a small prey hypercarnivore—similar to extant Canis simensis—the aforementioned affinities might have evolved independently, in relation to high stresses during feeding. Overall, our study demonstrates that morphological inspection and deformation-based geometric morphometrics complement each other and allow a thorough investigation of sinus shape variability, thus enabling the study of sinus morphology in other fossil carnivorans with the ultimate goal of inferring their ecological preferences.

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

The neighbouring sites of Berești and Mălușteni (Eastern Carpathian Foreland, eastern Romania) have yielded the most abundant and taxonomically diverse Pliocene vertebrate assemblages described so far from the entire country. Some of the small mammals found here were described as new taxa, and occasionally reassessed during the past one hundred years, but most of the material collected initially remained unrevised. Here, we provide a taxonomic revision of all the small mammal material (insectivores, rodents, and lagomorphs) that could be found in three main collections. The studied specimens were assigned to the insectivore families Desmanidae (Desmana verestchagini and Talpa sp.), and Erinaceidae (Erinaceus sp.); to the rodent families Muridae (Mimomys sp. or Promimomys sp.; Allocricetus sp.), Sciuridae (Spermophilus cf. nogaici), Spalacidae (Pliospalax macoveii), and Castoridae (Trogontherium minus, Castor fiber); and to the lagomorph families Leporidae (Trischizolagus dumitrescuae) and Ochotonidae (Ochotona ursui). Compared to the faunal assemblages described from Central-Eastern Europe, the identified taxa (some confirmed, others reassessed as synonyms) support an Early Pliocene age for the vertebrate assemblages from Berești and Mălușteni. Both faunal assemblages are assigned to the Ruscinian, with the faunas from Berești being considered geologically slightly older than the ones from Mălușteni.
