The specimen is a left adult mandibular corpus preserving strongly worn M2 and M3, fragmentary roots of P4 and M1, alveoli of canine and P3, and the lower half of the mandibular symphysis. In Southeast Asia, two Late Miocene medium-sized hominoids have been discovered so far: Lufengpithecus from the Yunnan Province, southern China, and Khoratpithecus from northern Thailand and central Myanmar. In particular, the mandibular specimen of Khoratpithecus was discovered from the neighboring village of Tebingan. However, the new mandible shows apparent differences from both genera in the shape of the outline of the mandibular symphyseal section. The new Tebingan mandible has a well-developed superior transverse torus, a deep intertoral sulcus (= genioglossal fossa), and a thin, shelf-like inferior transverse torus. In contrast, Lufengpithecus and Khoratpithecus each have very shallow intertoral sulcus and a thick, rounded inferior transverse torus. -

The Cleveland Museum of Natural History December 2007 Number 56:152–157 NYANZACHOERUS SYRTICUS (ARTIODACTYLA, SUIDAE) FROM THE LATE MIOCENE OF LEMUDONG’O, KENYA LESLEA J. HLUSKO Department of Integrative Biology University of California, 3060 Valley Life Sciences Building Berkeley, California 94720-3140 [email protected] AND YOHANNES HAILE-SELASSIE The Cleveland Museum of Natural History 1 Wade Oval Drive Cleveland, Ohio 44106-1767 ABSTRACT Lemudong’o Locality 1 is a late Miocene mammalian-dominated fossil site in the Narok District of southern Kenya. Suidae specimens from this site are scarce and fragmentary, however the recovered specimens can be confidently assigned to Nyanzachoerus syrticus based on the size and morphology of the third molars and the relative size of the third and fourth premolars. This species designation indicates a late Miocene/early Pliocene biochronological age, which accords with 40Ar/39Ar determinations of ,6.11 Ma (Deino and Ambrose, 2007). These Lemudong’o specimens indicate that N. syrticus inhabited the southern part of what is now Kenya by 6 Ma, the earliest known appearance of the species south of Lothagam, Kenya. Introduction The last decade has witnessed a dramatic increase in the recovery of late Miocene and early Pliocene mammalian fossils Lemudong’o is a 6-million-year-old fossil site in the Narok from sites in eastern and central Africa such as Lothagam (Harris District of southern Kenya (Ambrose et al., 2003, 2007; Deino and Leakey, 2003) and Lukeino (Pickford and Senut, 2001) in and Ambrose, 2007). Primarily, mammalian fossils have been Kenya, Aramis and the West Margin of the Middle Awash recovered from the Lemudong’o Locality 1 (LEM 1) and nearby (WoldeGabriel et al., 1994; Haile-Selassie et al., 2004) in Ethiopia, contemporaneous localities, consisting of a large number of the Warwire and Nkondo Formations in the Albertine Rift of colobine primates and hyracoids. -
Record of a Late Miocene Suid, Tetraconodon Intermedius from the Baripada Beds (Mayurbhanj, Orissa): Age Implications
Journal of the Palaeontological Society of India ISSN 0522-9630 Volume 58(2), December 2013: 213-218 RECORD OF A LATE MIOCENE SUID, TETRACONODON INTERMEDIUS FROM THE BARIPADA BEDS (MAYURBHANJ, ORISSA): AGE IMPLICATIONS K. MILANKUMAR SHARMA* and RAJEEV PATNAIK* *DEPARTMENT OF GEOLOGY (C. A. S.), PANJAB UNIVERSITY, CHANDIGARH-160014 Corresponding e-mail: [email protected] ABSTRACT The highly fossiliferous marine deposits of the Baripada Beds have been assigned ages ranging from Eocene to Pleistocene primarily based on biostratigraphically long-ranging foraminfers, molluscs and selachians. We describe here a short ranging (Late Miocene) suid, Tetraconodon intermedius from these beds for the first time. A detailed comparison and biostratigraphic correlation of our finding with similar finds from the Nagri-Dhok Pathan transition of the Siwalik of Jammu and the Irrawaddy beds of Myanmar allows us to provide a smaller age window of ~10-8 Ma to these beds. Keywords: Tetraconodon, Late Miocene, Biostratigraphy, Baripada Beds INTRODUCTION The Baripada Beds, which are considered to be deposited as a consequence of marine transgression (Modak, 1952), are well known for their diverse fossil assemblages: selachians, spine of Rays and Skates, bony fishes, molluscs and foraminifers. However, the precise geological age of these fossiliferous marine deposits has remained contentious for a long period of time due to the presence of long-ranging taxa. The current paper describes an isolated tooth of Tetraconodon intermedius, which is known from the Nagri-Dhok Pathan transition in Jammu Siwalik (Pilgrim, 1926). The present specimen was collected from the bluish grey sandy shale bed overlying the limestone deposits of Itamundia (Fig. -

A contribution to the evolutionary biology of Conohyus olujici n. sp. (Mammalia, Suidae, Tetraconodontinae) from the early Miocene of Lučane, Croatia Raymond L. BERNOR Shundong BI College of Medicine, Department of Anatomy, Laboratory of Evolutionary Biology, Howard University, 520 W St. N.W., Washington D.C. 20059 (USA) [email protected] [email protected] Jakov RADOVČIĆ Croatian Natural History Museum, Department of Geology and Paleontology, Demetrova 1, HR 10000 Zagreb (Croatia) [email protected] Bernor R. L., Bi S. & Radovčić J. 2004. — A contribution to the evolutionary biology of Conohyus olujici n. sp. (Mammalia, Suidae, Tetraconodontinae) from the early Miocene of Lučane, Croatia. Geodiversitas 26 (3) : 509-534. ABSTRACT We describe here the topotypic series of Conohyus olujici n. sp. from the Croatian locality of Lučane. This sample was originally collected by local lignite miners in the 1930’s, who conveyed the sample to the parish’s Franciscan monk Dr. Josip Olujić. The Lučane Conohyus sample includes seven lower jaws and jaw fragments; no upper cheek teeth have yet been recovered. Our use of bivariate statistics, log10 ratio diagrams and a cladistic analysis all reveal that C. olujici n. sp. is the most primitive member of the Conohyus clade. The analyses reveal that: of the sample considered, only two species are referable to Parachleuastochoerus, P. sp. and P. crusafonti; Parachleuastochoerus is the sister-taxon to Conohyus; Conohyus is a clade, KEY WORDS and C. olujici n. sp. is the sister-taxon of the C. steinheimensis-C. simorrensis Mammalia, and C. sindiensis clades. Conohyus olujici n. sp. would appear to have occurred Suidae, Tetraconodontinae, at a time when the genus enjoyed a relatively continuous geographic range Conohyus, that extended from southern Europe to South Asia. -
New Materials of Tetraconodon Malensis (Mammalia, Artiodactyla, Suidae) from the Middle Miocene of Central Myanmar
Universities Research Journal 2008, Vol. I, NO.2 New Materials of Tetraconodon malensis (Mammalia, Artiodactyla, Suidae) from the Middle Miocene ofCentral Myanmar l 2 Thaung Htike , Zin Maung Maung Thein and Hnin Hnin Htar Abstract In this study, we report the additional dental specimens of Tetraconodon malensis (Artiodactyla, Suidae) discovered near Nwegwe Village, Chaung-U Township, Sagaing Division, central Myanmar. The well preserved maxitlary and mandibular fragments of T. malensis, firstly recorded from the ,basal part of the Khabo Formation (Middle Miocene) provide new dental characteristics of this species: large P3 with salient buccal and linfual walls; longer and wider P3 relative to P4; extremely large p3 and P ; longer but not wider p3 relative to p4; minute M3 with indistinct talon; well developed buccal cingulum in upper molars. The additional dental characteristics of T. malensis elucidates the taxonomic status of this species among tetraconodont suids, suggesting that T. malensis may have originated in Myanmar and was derived from Conohyus sindiensis ofIndian Subcontinent during the Early Miocene. Key words: Middle Miocene, new materials, taxonomic status, Tetraconodon malensis Introduction The fossil suids ofMyanmar have been knOWI). since the earlier part of 19th Century (Clift, 1828). Most ofthe Myanmar suids were described or mentioned by Colbert (1938, 1943) and Pilgrim (1910a, 1926, 1927a). Among their descriptions, Tetraconodon minor Pilgrim 1910a is a well known species which has been collected from the earliest Late Miocene of Myanmar. Recently, new species of Tetraconodon, T. malensis, T. irramedius and T. irramagnus were described from the Miocene of Myanmar (Thaung-Htike et al. 2005, 2007). Tetraconodon has been suggested that it was originated in Myanmar by the first appearance of smallest and most primitive T. -

La massa corporea di un individuo, oltre alla sua morfologia e struttura, è una delle caratteristiche che influisce maggiormente sulla sua ecologia. La variazione della taglia (body size), sia che essa diminuisca o sia che essa aumenti, porta a cambiamenti importanti nell’ecologia della specie: influisce sulla sua “longevità stratigrafica” (per le specie fossili), sulla complessità delle strutture ornamentali, sulla capacità di occupare determinati habitat, sulla grandezza degli areali che possono occupare (range size), sull’abbondanza (densità di individui) che esse possono avere in un determinato areale, sulla capacità di sfruttare le risorse, sul ricambio generazionale, sulla loro capacità di dispersione e conseguentemente sulla capacità di sopravvivere ai mutamenti ambientali (in seguito ai mutamenti si estinguono o tendono a spostarsi per seguire condizioni ecologiche ottimali – habitat tracking). -

The Myth of the Hippo-Like Anthracothere: the Eternal Problem of Homology and Convergence
HYPOTHESES OF HIPPOPOTAMID ORIGINS 31 THE MYTH OF THE HIPPO-LIKE ANTHRACOTHERE: THE ETERNAL PROBLEM OF HOMOLOGY AND CONVERGENCE Martin PICKFORD Collège de France, and Département Histoire de la Terre, UMR 5143 du CNRS, Case postale 38, 57 rue Cuvier, 75005, Paris. e-mail: [email protected] Pickford, M. 2008. The myth of the hippo-like anthracothere: The eternal problem of homology and convergence. [El mito de la similitud entre antracoterios e hipopótamos: el eterno problema entre homología y convergencia.] Revista Española de Paleontología, 23 (1), 31-90. ISSN 0213-6937. ABSTRACT The notion that anthracotheres had hippo-like body proportions, locomotion and lifestyles has been in the lit- erature for so long, and has been repeated so many times, that it has taken on the aura of unquestionable truth. However, right from the beginning of studies into hippo-anthracothere relationships over a century and a half ago, observations were made that revealed the existence of fundamental differences in dental, cranial and post- cranial anatomy in the two groups. From 1836 to 1991 two skeletal characters (a descending plate at the angle of the mandible, and raised orbits) have overshadowed all others in suggesting close relationships between hippos and a single anthracothere genus (Merycopotamus) later to be joined by a second genus, Libycosaurus, in 1991 for the descending angle, and 2003 for the raised orbits (Lihoreau, 2003; Pickford, 1991). Close examination of these structures reveals that they are not homologous in the two groups, yet they have played an inordinately stubborn role in interpretations of the relationships between them, featuring in papers as recently as 2005. -
