[email protected] ABSTRACT – SYSTEMATIC UPDATE AND PHYLOGENY OF THE PROTEROTHERIIDAE (MAMMALIA, LITOPTERNA) FROM THE “MESOPOTAMIENSE” (LATE MIOCENE) OF ENTRE RÍOS PROVINCE, ARGENTINA. A systematic update of the species of Proterotheriidae (Litopterna) from the “Mesopotamiense” of Entre Ríos Province (Argentina) is performed, and their phylogenetic relationships with other members of the family are tested. Brachytherium cuspidatum Ameghino is validated (considered nomen dubium hitherto) and a sexual dimorphism is proposed for this species. This idea is based on metric, but not morphological, differences among the specimens included in it, which is supported by a discriminant analysis. Neobrachytherium ameghinoi Soria and Proterotherium cervioides Ameghino are also valid, and Epitherium? eversus (Ameghino) is assigned to the genus Diadiaphorus. Detailed descriptions of the specimens are presented for each taxon, and their diagnosis are revised. Key words: Proterotheriidae, Ituzaingó Formation, Entre Ríos Province, systematics, phylogeny. RESUMO – Uma atualização sistemática, das espécies de Proterotheriidae (Litopterna) presentes no “Mesopotamiense” da Província de Entre Ríos, Argentina, é realizada, bem como são testadas as suas relações fi logenéticas com outros integrantes da família. Brachytherium cuspidatum (previamente considerada nomen dubium) é revalidada, e um dimorfi smo sexual é proposto para esta espécie. -
Evolutionary and Functional Implications of Incisor Enamel Microstructure Diversity in Notoungulata (Placentalia, Mammalia)
Journal of Mammalian Evolution https://doi.org/10.1007/s10914-019-09462-z ORIGINAL PAPER Evolutionary and Functional Implications of Incisor Enamel Microstructure Diversity in Notoungulata (Placentalia, Mammalia) Andréa Filippo1 & Daniela C. Kalthoff2 & Guillaume Billet1 & Helder Gomes Rodrigues1,3,4 # The Author(s) 2019 Abstract Notoungulates are an extinct clade of South American mammals, comprising a large diversity of body sizes and skeletal morphologies, and including taxa with highly specialized dentitions. The evolutionary history of notoungulates is characterized by numerous dental convergences, such as continuous growth of both molars and incisors, which repeatedly occurred in late- diverging families to counter the effects of abrasion. The main goal of this study is to determine if the acquisition of high-crowned incisors in different notoungulate families was accompanied by significant and repeated changes in their enamel microstructure. More generally, it aims at identifying evolutionary patterns of incisor enamel microstructure in notoungulates. Fifty-eight samples of incisors encompassing 21 genera of notoungulates were sectioned to study the enamel microstructure using a scanning electron microscope. We showed that most Eocene taxa were characterized by an incisor schmelzmuster involving only radial enamel. Interestingly, derived schmelzmusters involving the presence of Hunter-Schreger bands (HSB) and of modified radial enamel occurred in all four late-diverging families, mostly in parallel with morphological specializations, such as crown height increase. Despite a high degree of homoplasy, some characters detected at different levels of enamel complexity (e.g., labial versus lingual sides, upper versus lower incisors) might also be useful for phylogenetic reconstructions. Comparisons with perissodactyls showed that notoungulates paralleled equids in some aspects related to abrasion resistance, in having evolved transverse to oblique HSB combined with modified radial enamel and high-crowned incisors. -

Reveals That Glyptodonts Evolved from Eocene Armadillos

Although glyptodonts were an important component of Cenozoic South American faunas, their early evolution and phylogenetic affinities within the order Cingulata (armoured New World placental mammals) remain controversial. In this study, we used hybridization enrichment and high-throughput sequencing to obtain a partial mitochondrial genome from Doedicurus sp., the largest (1.5 m tall, and 4 m long) and one of the last surviving glyptodonts. Our molecular phylogenetic analyses revealed that glyptodonts fall within the diver- sity of living armadillos. Reanalysis of morphological data using a molecular ‘back- bone constraint’ revealed several morphological characters that supported a close relationship between glyptodonts and the tiny extant fairy armadillos (Chlamyphori- nae). -

Functional Relationship Between Skull Form and Feeding Mechanics in Sphenodon, and Implications for Diapsid Skull Development
Functional Relationship between Skull Form and Feeding Mechanics in Sphenodon, and Implications for Diapsid Skull Development Neil Curtis1*, Marc E. H. Jones2, Junfen Shi1, Paul O’Higgins3, Susan E. Evans2, Michael J. Fagan1 1 Medical and Biological Engineering Research Group, Department of Engineering, University of Hull, Hull, United Kingdom, 2 Research Department of Cell and Developmental Biology, University College London, London, United Kingdom, 3 Hull-York Medical School, University of York, York, United Kingdom Abstract The vertebrate skull evolved to protect the brain and sense organs, but with the appearance of jaws and associated forces there was a remarkable structural diversification. This suggests that the evolution of skull form may be linked to these forces, but an important area of debate is whether bone in the skull is minimised with respect to these forces, or whether skulls are mechanically ‘‘over-designed’’ and constrained by phylogeny and development. Mechanical analysis of diapsid reptile skulls could shed light on this longstanding debate. Compared to those of mammals, the skulls of many extant and extinct diapsids comprise an open framework of fenestrae (window-like openings) separated by bony struts (e.g., lizards, tuatara, dinosaurs and crocodiles), a cranial form thought to be strongly linked to feeding forces. We investigated this link by utilising the powerful engineering approach of multibody dynamics analysis to predict the physiological forces acting on the skull of the diapsid reptile Sphenodon. We then ran a series of structural finite element analyses to assess the correlation between bone strain and skull form. With comprehensive loading we found that the distribution of peak von Mises strains was particularly uniform throughout the skull, although specific regions were dominated by tensile strains while others were dominated by compressive strains. -

CENTRAL AMERICAN PROVINCIALISM AND THE GREAT AMERICAN BIOTIC INTERCHANGE Michael O. Woodburne1,* Alberto L. Cione2,**, and Eduardo P. Tonni2,*** ABSTRACT The age and phyletic context of mammals that dispersed between North and South America during the past 9 m.y. is summarized. The presence of a Central American province of cladogenesis and faunal differentiation is explored. One apparent aspect of such a province is to delay dispersals of some taxa northward from Mexico into the continental United States, largely during the Blancan. Examples are recognized among the various xenar- thrans, and cervid artiodactyls. Whereas the concept of a Central American province has been mentioned in past investigations it is upgraded here. Paratoceras (protoceratid artio- dactyl) and rhynchotheriine proboscideans provide perhaps the most compelling examples of Central American cladogenesis (late Arikareean to early Barstovian and Hemphillian to Rancholabrean, respectively), but this category includes Hemphillian sigmodontine rodents, and perhaps a variety of carnivores and ungulates from Honduras in the medial Miocene, as well as peccaries and equids from Mexico. For South America, Mexican canids and hy- drochoerid rodents may have had an earlier development in Mexico. Remarkably, the first South American immigrants to Mexico (after the Miocene heralds; the xenarthrans Plaina and Glossotherium) apparently dispersed northward at the same time as the first Holarctic taxa dispersed to South America (sigmodontine rodents and the tayassuid artiodactyls). -
