A high degree of variation was found in the plastral formula and in the shape and size of the intergular scute. This study suggests that the Amazon population of matamatas is different from the Orinoco population in the following characters: shape ofthe carapace, plastral pigmentation, and coloration on the underside of the neck. Additionatly, a preliminary analysis indicates that the two populations could be separated on the basis of the allometric growth of the carapace in relation to the plastron.

Xinjiangchelyids provide us with great insights into the plesiomorphic anatomy of crown-cryptodires, the most diverse group of living turtles, and they are particularly relevant for understanding the origin and early divergence of the primary clades of extant turtles. Results: Exceptionally complete new xinjiangchelyid material from the ?Qigu Formation of the Turpan Basin (Xinjiang Autonomous Province, China) provides new insights into the anatomy of this group and is assigned to Xinjiangchelys wusu n. sp. A phylogenetic analysis places Xinjiangchelys wusu n. sp. in a monophyletic polytomy with other xinjiangchelyids, including Xinjiangchelys junggarensis, X. radiplicatoides, X. levensis and X. latiens. However, the analysis supports the unorthodox, though tentative placement of xinjiangchelyids and sinemydids outside of crown-group Testudines. A particularly interesting new observation is that the skull of this xinjiangchelyid retains such primitive features as a reduced interpterygoid vacuity and basipterygoid processes.

Of those that have been assessed on the IUCN Red List, 63% are considered threatened, and 10% are critically endangered, with ca. 42% of all known turtle species threatened. Without directed strategic conservation planning, a significant portion of turtle diversity could be lost over the next century. Toward that conservation effort, we compiled museum and literature occurrence records for all of the world’s tortoises and freshwater turtle species to determine their distributions and identify priority regions for conservation.

    Demographic Consequences of Superabundance in Krefft's River

    i The comparative ecology of Krefft’s River Turtle Emydura krefftii in Tropical North Queensland. By Dane F. Trembath B.Sc. (Zoology) Applied Ecology Research Group University of Canberra ACT, 2601 Australia A thesis submitted in fulfilment of the requirements of the degree of Masters of Applied Science (Resource Management). August 2005. ii Abstract An ecological study was undertaken on four populations of Krefft’s River Turtle Emydura krefftii inhabiting the Townsville Area of Tropical North Queensland. Two sites were located in the Ross River, which runs through the urban areas of Townsville, and two sites were in rural areas at Alligator Creek and Stuart Creek (known as the Townsville Creeks). Earlier studies of the populations in Ross River had determined that the turtles existed at an exceptionally high density, that is, they were superabundant, and so the Townsville Creek sites were chosen as low abundance sites for comparison. The first aim of this study was to determine if there had been any demographic consequences caused by the abundance of turtle populations of the Ross River. Secondly, the project aimed to determine if the impoundments in the Ross River had affected the freshwater turtle fauna. Specifically this study aimed to determine if there were any difference between the growth, size at maturity, sexual dimorphism, size distribution, and diet of Emydura krefftii inhabiting two very different populations. A mark-recapture program estimated the turtle population sizes at between 490 and 5350 turtles per hectare. Most populations exhibited a predominant female sex-bias over the sampling period. Growth rates were rapid in juveniles but slowed once sexual maturity was attained; in males, growth basically stopped at maturity, but in females, growth continued post-maturity, although at a slower rate.

Marcos Jannello 2018 Resumen Las inusuales estructuras óseas observadas entre los vertebrados, como el cuello largo de la jirafa o el cráneo en forma de T del tiburón martillo, han interesado a los científicos desde hace mucho tiempo. Uno de estos casos es el clado Testudinata el cual representa uno de los grupos más fascinantes y enigmáticos conocidos entre de los amniotas. Su inconfundible plan corporal, que ha persistido desde el Triásico tardío hasta la actualidad, se caracteriza por la presencia del caparazón, el cual encierra a las cinturas, tanto pectoral como pélvica, dentro de la caja torácica desarrollada. Esta estructura les ha permitido a las tortugas adaptarse con éxito a diversos ambientes (por ejemplo, terrestres, acuáticos continentales, marinos costeros e incluso marinos pelágicos). Su capacidad para habitar diferentes nichos ecológicos, su importante diversidad taxonómica y su plan corporal particular hacen de los Testudinata un modelo de estudio muy atrayente dentro de los vertebrados. Una disciplina que ha demostrado ser una herramienta muy importante para abordar varios temas relacionados al caparazón de las tortugas, es la paleohistología. Esta disciplina se ha involucrado en temas diversos tales como el origen del caparazón, el origen del desarrollo y mantenimiento de la ornamentación, la paleoecología y la sistemática.

    www.nature.com/scientificreports OPEN An early bothremydid from the Arlington Archosaur Site of Texas Brent Adrian1*, Heather F. Smith1, Christopher R. Noto2 & Aryeh Grossman1 Four turtle taxa are previously documented from the Cenomanian Arlington Archosaur Site (AAS) of the Lewisville Formation (Woodbine Group) in Texas. Herein, we describe a new side-necked turtle (Pleurodira), Pleurochayah appalachius gen. et sp. nov., which is a basal member of the Bothremydidae. Pleurochayah appalachius gen. et sp. nov. shares synapomorphic characters with other bothremydids, including shared traits with Kurmademydini and Cearachelyini, but has a unique combination of skull and shell traits. The new taxon is signifcant because it is the oldest crown pleurodiran turtle from North America and Laurasia, predating bothremynines Algorachelus peregrinus and Paiutemys tibert from Europe and North America respectively. This discovery also documents the oldest evidence of dispersal of crown Pleurodira from Gondwana to Laurasia. Pleurochayah appalachius gen. et sp. nov. is compared to previously described fossil pleurodires, placed in a modifed phylogenetic analysis of pelomedusoid turtles, and discussed in the context of pleurodiran distribution in the mid-Cretaceous. Its unique combination of characters demonstrates marine adaptation and dispersal capability among basal bothremydids. Pleurodira, colloquially known as “side-necked” turtles, form one of two major clades of turtles known from the Early Cretaceous to present 1,2. Pleurodires are Gondwanan in origin, with the oldest unambiguous crown pleurodire dated to the Barremian in the Early Cretaceous2. Pleurodiran fossils typically come from relatively warm regions, and have a more limited distribution than Cryptodira (hidden-neck turtles)3–6. Living pleurodires are restricted to tropical regions once belonging to Gondwana 7,8.
