Asian Paleocene and early Eocene strata are subdivided into four biochronological units based on the fossil mammals (Land Mammal Ages). From oldest to youngest, they are the Shanghuan, the Nongshanian, the Gashatan, and the Bumbanian Asian Land Mammal Ages (ALMA). Recent paleomagnetic data from the Nanxiong Basin indicate that the base of the Shanghuan lies about 2/3 the way up Chron C29r. Nanxiong data and recent paleomagnetic and isotopic results from the Chijiang Basin show that the Shanghuan-Nongshanian ALMA boundary lies between the upper part of Chron C27n and the lower part of Chron C26r, close to the Chron C27n-C26r reversal. -

A New Mammalian Fauna from the Earliest Eocene (Ilerdian) of the Corbie`Res (Southern France): Palaeobiogeographical Implications
Swiss J Geosci (2012) 105:417–434 DOI 10.1007/s00015-012-0113-5 A new mammalian fauna from the earliest Eocene (Ilerdian) of the Corbie`res (Southern France): palaeobiogeographical implications Bernard Marandat • Sylvain Adnet • Laurent Marivaux • Alain Martinez • Monique Vianey-Liaud • Rodolphe Tabuce Received: 27 April 2012 / Accepted: 19 September 2012 / Published online: 4 November 2012 Ó Swiss Geological Society 2012 Abstract A new mammal fauna from the earliest Eocene Keywords Ypresian Á Europe Á Mammals Á of Le Clot (Corbie`res, Southern France) is described.

The status of CASG 71892 as the oldest known record of either of the two spp. of Uria was recently confirmed by the review of Watanabe et al. (2016). The younger of the two marine transgressions at the Tolstoi Point corresponds to the Bigbendian transgression (Olson, 2013), which contains the Gauss-Matuyama magnetostratigraphic boundary (Kaufman and Brigham-Grette, 1993). Attempts to date this reversal have been recently reviewed by Ohno et al. (2012); Singer (2014), and Head (2019). In particular, Deino et al. (2006) were able to tightly bracket the age of the reversal using high-precision 40Ar/39Ar dating of two tuffs in normally and reversely magnetized lacustrine sediments from Kenya, obtaining a value of 2.589 ± 0.003 Ma. -
A New Paleocene Nyctitheriid Insectivore from Inner Mongolia (China) and the Origin of Asian Nyctitheriids
A new Paleocene nyctitheriid insectivore from Inner Mongolia (China) and the origin of Asian nyctitheriids PIETER MISSIAEN and THIERRY SMITH Missiaen, P. and Smith, T. 2005. A new Paleocene nyctitheriid insectivore from Inner Mongolia (China) and the origin of Asian nyctitheriids. Acta Palaeontologica Polonica 50 (3): 513–522. Nyctitheriids are primitive insectivores that were relatively abundant and diverse in North America and Europe during the middle Paleocene through to the middle Oligocene. The nyctitheriids from Asia are poorly known and show several distinctive characters. Here we describe the late Paleocene Asionyctia guoi gen. et sp. nov., the first fairly well known Asian nyctitheriid, from the Subeng locality near the city of Erlianhot (Erenhot) in Inner Mongolia, China. Among its most conspicuous features are the paraconid positioned high on p4, the rather primitive morphology and size of p3, the premolariform P4/p4 and the transverse upper molars with a small, straight postcingulum. Except for the paraconid po− sitioned high on p4, these combined features are also present in other Asian nyctitheriids, but absent in North American or European forms. We performed a cladistic analysis, based on a set of 20 dental characters, to resolve higher−level phylogenetic relations within Nyctitheriidae. The strict consensus tree groups all Asian forms in a single clade, for which we propose the rank of a subfamily and the name Asionyctiinae subfam. nov. Within Nyctitheriidae, a semimolariform P4/p4, as in Leptacodon tener, is considered primitive, and we consider the morphologically simpli− fied P4/p4 of Asionyctiinae derived within Nyctitheriidae. Asionyctiinae can be derived from an American, primitive Leptacodon−like ancestor migrating into Asia, with the reduction of P4/p4 occurring on the Asian continent. -

Museum of Dear Museum Friends and Family, Natural Science Director and It has been a long tumultuous year. The end, however, Curators is near. The sun is out, the air is warm, and spring has definitely sprung here in south Louisiana. Along with the joy to the end of winter we find ourselves at the end of a long pandemic year with vaccinations at an Christopher C. Austin all-time high. This is good news for all of us as we move Director John Stauffer McIlhenny into the summer and return to a hopefully more normal fall. Despite all of the Professor and Curator of difficulties of the last year, I’m very proud of our Museum curators, staff and Amphibians & Reptiles students who pivoted to accomplish some great science over the last year. On the next page curator Prosanta Chakrabartry writes about the importance Robb T. Brumfield of evolutionary biology in the development of vaccines. In this issue, you will Roy Paul Daniels Professor and Curator of also read about a literally large new species discovery in the Gulf of Mexico, Genetic Resources our expanded infrastructure for our genetic resource collection, and some fantastic archeological research and more. Prosanta Chakrabarty Professor One of the greatest pleasures we curators enjoy is when Museum folks fledge Curator of Fishes and move on to accomplish great things. -

The PETM is characterized by a globally quasi-uniform 5–8 8C warming and large changes in ocean chemistry and biotic response. The warming is associated with a negative carbon isotope excursion (CIE), reflecting geologically rapid input of large amounts of isotopically light CO2 and/or CH4 into the exogenic (ocean–atmosphere) carbon pool. The biotic response on land and in the oceans was heterogeneous in nature and severity, including radiations, extinctions and migrations. Recently, several events that appear -

At least 12 mammal-bearing horizons have been recognized in these formations, of which 4 in the Nomogen Formation, 6 in the Arshanto Formation, and 2 in the Irdin Manha Formation. Recent investigation proved that the “Houldjin Formation” recognized in this area by the Central Asi- atic Expeditions (CAE) of the American Museum Natural History in the 1920s is actually the Irdin Manha Formation, while the “Irdin Manha Formation” of CAE is the Arshanto Formation. A recent paleomagnetic study suggests that the upper part of the Nomogen Formation is early Eocene in age and the Arshanto Formation is mainly early Eocene rather than middle Eocene as previously thought. -
