Here we describe the first record of a chalicothere from the Miocene of Myanmar. The chalicothere, documented by a par− tial mandible, was unearthed from the lower portion of the Irrawaddy Formation in the region of Magway, Central Myanmar. The Burmese material belongs to an early late Miocene fauna which recently yielded hominoid remains attrib− uted to Khoratpithecus. The specimen, which is a...

During drilling of Leg 160 in the Eastern Mediterranean (April−May, 1995), Messinian (i.e., uppermost Miocene) facies were identified at a site at the base of the Cyprus slope (Site 968) and at two sites on the Eratosthenes Seamount (Sites 965 and 967). The new results can be compared with the recovery of Messinian evaporites from the Florence Rise west of Cyprus (Deep Sea Drilling Project Site...

The phylogenetic position of many fossil platyrrhines with respect to extant ones is not yet clear. Two main hypotheses have been proposed: the layered or successive radiations hypothesis suggests that Patagonian fossils are Middle Miocene stem platyrrhines lacking modern descendants, whereas the long lineage hypothesis argues for an evolutionary continuity of all fossil platyrrhines with the e...

Although Cenozoic protoceratid artiodactyls are known from throughout North America, species referred to the Miocene protoceratine Paratoceras are restricted to subtropical areas of the Gulf Coast and southern Mexico and tropical areas of Panama. Newly discovered fossils from the late Arikareean Lirio Norte Local Fauna, Panama Canal basin, include partial dentitions of a protoceratid remarkably...

The main goals of this study were to increase the data quality of the SPOT XS imagery for diVerentiation of several rock units and to expose the structural features of the southern part of the Sivas Tertiary Basin. With these aims, both edge enhancement and histogram equalized stretching Ž lters were applied to SPOT XS imagery of the southern part of the basin. Various geological observations a...

A new geoemydid turtle, Ocadia tanegashimensis (Testudines: Geoemydidae) is described on the basis of a relatively well-preserved shell from the lower middle Miocene of Tanegashima Island, Kagoshima Prefecture, southwestern Japan. This species is clearly distinguished from two congeneric species (extant O. sinensis and O. nipponica from the middle Pleistocene of eastern Japan) due to the presen...

Oxygen isotopes in marine sulfate (delta18O(SO4)) measured in marine barite show variability over the past 10 million years, including a 5 per mil decrease during the Plio-Pleistocene, with near-constant values during the Miocene that are slightly enriched over the modern ocean. A numerical model suggests that sea level fluctuations during Plio-Pleistocene glacial cycles affected the sulfur cyc...

We summarize information concerning Recent and Pleistocene-Holocene Uruguayan sand dollars (Mellitidae), as well as Miocene taxa (Monophorasteridae). Recent and Pleistocene-Holocene species (Encope emarginata, Mellita quinquiesperforata, and Leodia sexisperforata) are at their southernmost limits of distribution, with only E. emarginata recorded further south than Uruguay. Lower temperatures to...
