The morphological and molecular evidence for higher-level reptile relationships is reassessed, A combined analysis of 176 osteological, 40 soft anatomical, and 2903 (1783 aligned) molecular characters in 28 amniote taxa yields the traditional reptile tree. Synapsids (including mammals) are the sister taxon to all other amniotes, including all extant reptiles. Turtles group with anapsid parareptiles and fall outside a monophyletic Diapsida. Within diapsids, squamates and Sphenodon form a monophyletic Lepidosauria, and crocodiles plus birds form a monophyletic Archosauria. This tree is identical to the tree strongly supported by the osteological data alone when fossils are included. In a combined analysis the strong osteological signal linking turtles with... |

We report a total of 57 type specimens (31 primary and 26 secondary) belonging to 27 nominal species of chelonians (23) and crocodilians (4) in the collection of the Netherlands Centre for Biodiversity Naturalis Leiden, the Netherlands. Fragments of fossil crocodilians have not been included in the specimen count. We provide the original name and publication, type locality, synonyms under which type specimens have been cited in the literature, current name, comments on the type material, its history, and its status and provide information on illustrations. |

Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have... |

The origin and evolution of the crown-group of turtles (Cryptodira + Pleurodira) is one of the most interesting topics in turtle evolution, second perhaps only to the phylogenetic position of turtles among amniotes. The present contribution focuses on the former problem, exploring the phylogenetic relationships of extant and extinct turtles based on the most comprehensive phylogenetic dataset of morphological and molecular data analyzed to date. Parsimony analyses were conducted for different partitions of data (molecular and morphological) and for the combined dataset. In the present analysis, separate analyses of the molecular data always retrieve Pleurodira allied to Trionychia. Separate analysis of the morphological dataset, by contrast, depicts a more... |

Nesting activity of the neotropical turtle Phrynops hilarii Duméril & Bibron, 1835 was studied from Feb/94 through Jan/95, with weekly visits at the Lami Biological Reserve (30º15'S, 51º05'W), Porto Alegre, Rio Grande do Sul, Brazil. Nesting behavior was observed 17 times on three different nest sites. Phrynops hilarii laid in average 11 eggs per clutch (10-14; sd±1; n=17), nests' depth ranged from 100 to 150 mm (x=121.53 mm.sd±12.31; n=17). The species presents stereotiped behaviour common to other Testudines. Temperature inside the nest, just after nesting, ranged between 20-31ºC (x=26.29ºC; sd±2.89; n=17); nest predation during this period was 82.35% (14 of 17 nests). From Aug/29 through Oct/03/95, 220 egg shells was collected next to 21 nests... |

Este estudio revisa la distribución para el Caribe colombiano de las especies Kinosternon scorpioides, Trachemys callirostris, Mesoclemmys dahli y Chelonoidis carbonaria y nuevas localidades en la distribución de dichas especies para la región. La especie K. scorpioides es registrada por primera vez en la cuenca del río Manzanares, en Santa Marta, Magdalena. Trachemys callirostris fue registrada en el río Cañas, La Guajira, constituyéndose en el primer registro para la especie en un riachuelo de la cara norte de la Sierra Nevada de Santa Marta. Chelonoidis carbonaria fue registrada en un humedal ubicado en la ciudad de Santa Marta. Se registró una hembra de M. dahli en el corregimiento Monterrubio, municipio Sabana de San Ángel, Magdalena. Tres de las... |

This is a review article on the fossil record of turtles in Colombia that includes: the early Cretaceous turtles from Zapatoca and Villa de Leyva localities; the giant turtles from the Paleocene Cerrejón and Calenturitas Coal Mines; the early Miocene, earliest record of Chelus from Pubenza, Cundinamarca; the early to late Miocene large podocnemids, chelids and testudinids from Castilletes, Alta Guajira and La Venta; and the small late Pleistocene kinosternids from Pubenza, Cundinamarca. I also discuss here the current gaps in the fossil record of tropical South American turtles, as well as the ongoing research and future projects to be developed in order to understand better the evolutionary history of Colombian turtles. |

ABSTRACT The citations contained in a recent literature review on the freshwater turtle and tortoise species of Colombia were analyzed. Publishing rates on these species have been increasing exponentially since the 1950s, although many of the publications would not be detected using internet-based literature searches. The most common topics of publications were systematics and phylogeography, nesting ecology, and management. In the 1970s and 1980s, the rate of publishing on the ecology and genetics of Colombian populations lagged behind the rate of publishing on these topics for populations of Colombian freshwater turtle and tortoise species located in other countries, but currently the production of the two regions is comparable. Also, in other countries... |
