A nearly complete skeleton of an erycine boid is described from the Ypresian-Lutetian (early-middle Eocene) site Messel, Germany, for which we propose name Rageryx schmidi n. gen., sp. The animal had a total length c. 52 cm, with 258 vertebrae. In skull proportions it similar to ungaliophiine boids, especially Ungaliophis, and Tropidophis. distinctive accessory processes distal caudal vertebrae...

We describe a near-complete, three-dimensionally preserved skeleton of a metatherian (relative of modern marsupials) from the middle Eocene (Lutetian: 44-43 million years ago) Lülük member of the Uzunçarşıdere Formation, central Turkey. With an estimated body mass of 3-4 kg, about the size of a domestic cat (Felis catus) or spotted quoll (Dasyurus maculatus), it is an order of magnitude larger ...

Abstract New mapping and dating of volcanic outcrops on the east coast Admiralty Bay, King George Island, has demonstrated that Eocene sequences are dominant also crop out extensively elsewhere, particularly eastern part island. The can be divided into at least three formations (Hennequin, Cape Vauréal Carruthers Cliff) together with strata Warkocz near Lions Rump currently unassigned stratigra...

The article provides an overview of all known 39 localities the Paleogene turtles Eastern Europe. Numerous remains are described for first time from 19 localities, which six new, and 13 materials were only mentioned previously. Among them Pan-Trionychidae indet., Pan-Cheloniidae Dermochelyidae indet. Pan-Testudines as well pan-cheloniids Argillochelys sp. Ypresian Novoivanovka or Lutetian Gruzi...

The integration of sedimentological and structural data in the western end of the Ripoll syncline allows a clearer understanding of the palaeogeography of the area between the oblique termination of the Pedraforca thrust sheet and the frontal Vallfogona thrust during middle Eocene times. In this region, a 2.5-km thick clastic succession corresponding to the Bellmunt and Milany sequences infille...

The rise of the Isthmus of Panama, linked to a number of climatic, paleoceanographic, and biological events, has been studied mostly from indirect, often distal, geochemical and biotic evidence. We have upgraded existing geologic mapping in central Panama with more than 2000 fi eld stations, over 40 petrographic analyses, and more than 30 new geochronological and thermo chrono logical analy ses...

Calcareous nannofossil biostratigraphy and carbon-isotope stratigraphy on bulk organics of the middle-upper Eocene Souar Formation (Tunisia) allow for a refined this interval in southwestern Neo-Tethys margin. The represents deepest sedimentary deposits central northern Tunisian Basin was only dated previously by coarse data planktonic foraminifera. Together with our new data, correlation is pr...

introduction the study area is a small part of the urumieh-dokhtar structural zone in the markazi province, located in the northeastern part of the farmahin, north of arak (hajian, 1970). the volcanic rocks studied from the area include andesite, dacite, rhyodacite, ignimbrite and tuff of middle to late eocene age (middle lutetian to upper lutetian) (ameri et al., 2009). it seems that folding a...

The northern margin of the Organyà basin (Southern Pyrenees) has a complex structure in which syn-rift Lower Cretaceous carbonates flank wide Keuper evaporite province, featuring leading edges basement-involved thrust sheets Pyrenean antiformal stack. Recent studies show that diapirs and salt walls grew during extensional episode, conditioning development differentiated depocenters minibasins. ...
