Origin, Evolution and Biogeographic History of South by Marcelo S. de la Fuente, Juliana Sterli, Ignacio Maniel

By Marcelo S. de la Fuente, Juliana Sterli, Ignacio Maniel

The prolonged continental South American turtle list (Norian to Lujanian) permits us to stick to the evolution of this reptile clade from its origins. a number of major stem turtle taxa reminiscent of: Palaeochersistalampayensis and Condorchelys antiqua supply info at the first steps of turtle evolution. Others comparable to: Chubutemys copelloi or Patagoniaemys gasparinae supply clues to the beginning of the weird horned tortoises of the clade Meiolaniidae. The panpleurodiran species comparable to Notoemys laticentralis or Notoemys zapatocaensis shed mild at the foundation of contemporary pleurodiran turtles. This booklet explores aquatic and terrestrial cryptodiran turtles, South Gondwana pleurodiran turtles, North Gondwana pleurodiran turtles; Meiolaniforms and early differentiation of Mesozoic turtles.

Biodiversity Response to Climate Change in the Middle Pleistocene: The Porcupine Cave Fauna from Colorado

This publication chronicles the invention and research of animal fossils present in the most vital paleontological websites within the world-Porcupine Cave, positioned at an elevation of 9,500 ft within the Colorado Rocky Mountains. With tens of millions of pointed out specimens, this web site has turn into the main resource of knowledge at the fauna of North America's better elevations among nearly 1 million and 600,000 years in the past, a interval that observed the improvement and retreat of glaciers various occasions.

Fossil Reptiles of Great Britain

British Fossil reptile websites are of foreign significance in view that they comprise continues to be that fill the time gaps poorly recognized in other places. They contain wealthy vintage reptile beds which were the resource of dozens of significant specimens. This quantity information all these websites that experience yielded fossil reptiles.

The Great American Biotic Interchange: A South American Perspective

South American ecosystems suffered one of many maximum biogeographical occasions, after the institution of the Panamian land bridge, known as the “Great American Biotic Interchange” (GABI). This refers back to the alternate, in numerous levels, of land mammals among the Americas; this occasion all started through the past due Miocene with the looks of the Holartic Procyonidae (Huayquerian Age) in South the United States and maintains this day.

The second fallacy lies in Moll and Legler (1971) model itself. Nonetheless, results of recent molecular phylogenies for Central and South American slider turtles suggest that South America was invaded by these turtles from Central America at least twice (Fritz et al. 2012). In this context the first lineage to have colonized South America was the clade T. dorbigni + T. adiutrix (as a subspecies of T. dorbigni in Fritz et al. 2012) prior to the emergence of the Panamanian land bridge, whereas T.

These authors pointed out that Ch. donosobarrosi is a junior synonymous of Ch. chilensis. Although Richard (1999) recognized two species, the designation is different from Fernández (1988) and Cabrera (1998). 1 Testudinidae Batsch 1788 39 (1999) recognized Ch. chilensis (northern populations), including Ch. petersi as a synonym, and Ch. donosobarrosi (southern populations). In contrast with these taxonomic decisions, Ernst and Barbour (1989) and Ernst et al. (2000) identified only one species: Ch.
