“…Although the individual survived the injury, the hind limb injury may have caused difficulty in escaping from natural predators when the animal was alive. However, unlike carnivorans in which fast and swift moves as essential predatory abilities affect hunting success 50 , an injured leg may not be so fatal for multituberculates that are generally considered as omnivorous or herbivorous 2 51 52 .…”

A new multituberculate, Yubaartar zhongyuanensis gen. and sp. nov., is reported from the Upper Cretaceous of Luanchuan County, Henan Province, China. The holotype of the new taxon is a partial skeleton with nearly complete cranium and associated lower jaws with in situ dentitions. The new species is the southern-most record of a Late Cretaceous multituberculate from outside of the Mongolian Plateau in Asia and represents the largest known Mesozoic multituberculate from Eurasia. The new specimen displays some intriguing features previously unknown in multituberculates, such as the first evidence of replacement of the ultimate upper premolar and a unique paleopathological case in Mesozoic mammals in which the animal with a severely broken right tibia could heal and survive in natural condition. The phylogenetic analysis based on craniodental characters places Yubaartar as the immediate outgroup of Taeniolabidoidea, a group consisting of a North American clade and an Asian clade. This relationship indicates at least a faunal interchange of multituberculates before the K-Pg transition. The new evidence further supports the hypothesis that disparity in dental complexity, which relates to animal diets, increased with generic richness and disparity in body size, and that an adaptive shift towards increased herbivory across the K-Pg transitional interval.

“…On the contrary, the middle Miocene primitive saber-toothed felid Pseudaelurus quadridentatus had a robust Mc I (Ginsburg 1961a;Salesa et al 2010a;Peigné 2012), even more than the extant large pantherin felines (Salesa et al 2010a), in accordance with the huge dewclaw and robust forelimbs present in Machairodontinae, traits developed for achieving the rapid immobilization of prey (Gonyea 1976a;Emerson and Radinsky 1980;Akersten 1985;Rawn-Schatzinger 1992;Turner and Antón 1997;Salesa et al 2005Salesa et al , 2006aSalesa et al , 2010aSalesa et al , 2014. The small Mc I of L. vallesiensis would also help in reducing the weight of the forelimb, and thus the energy employed when moving on the ground.…”

The Spanish late Miocene locality of Batallones-1 yielded a rich sample of large carnivorans, including saber-toothed felids, amphicyonids, and ailurids, but also of smaller species, with the small cats being especially interesting. Two species are known from Batallones-1, one of them the size of a wildcat, Felis silvestris, the other one the size of a caracal, Caracal caracal. The former is represented by skulls, mandibles, and postcranial bones, whereas the latter is known from a collection of long bones. Both species are less abundant than their larger relatives, the saber-toothed felids Promegantereon ogygia and Machairodus aphanistus, but the available sample allows us to assess body proportions and adaptations of the smallest species, and to propose a new genus for this feline, Leptofelis vallesiensis. Its limb bones are remarkably gracile compared to fossils of the earlier genera Pseudaelurus, Miopanthera, and Styriofelis, and comparable in cursorial adaptations to the wildcat, very different from extant arboreal cats. While middle Miocene felids were likely semiarboreal forest dwellers, L. vallesiensis would be mostly terrestrial, climbing essentially for protection. This indicates an adaptation to a mosaic of habitats, including relatively open terrain, and may be related to the climatic changes detected in Eurasia during the late Miocene.

We report here the first case of bilateral mandibular hypodontia for a notoungulate, further associated with exostosis on various limb bones. We describe a partial skeleton of a palaeopathological individual of the notoungulate mesotheriid Plesiotypotherium achirense, from the Upper Miocene site of Achiri, Bolivian Altiplano. The main pathology is hypodontia of two first molars on both sides of the jaw. Other craniomandibular affliction, likely related to the latter pathology, are a striking overgrowth of two first upper molars on both sides and the anomalous development of masticatory muscle insertions (m. masseter, pterygoideus medialis, temporalis, and temporalis pars profundis). The pathological sequence of the masticatory apparatus was reconstructed in this individual according to distinctive wear of ever-growing crowns of two first upper molars, and the unequal lower alveoli reabsorption. Additional pathologies are exostoses observed on several articular surfaces of limb bones, from the scapula to distal phalanges. They likely decreased the range of movements during locomotion of this individual. Given its multiple pathologies, we might have expected this abnormal individual to be a potential easy prey. However, the long-time survival of this animal suggests a low predatory pressure in this area at that time, a hypothesis which is consistent with the virtual absence of flesh-eating vertebrates in the Achiri fossil record.
