TL;DR: New Pleistocene fossilized turtle remains from five localities of western Ecuador are described here, belonging to three different lineages of cryptodires (“hidden-necked” turtles) and the first fossil record of chelydrids, Chelydra, in the entirety of Central and South America.
Abstract: New Pleistocene fossilized turtle remains from five localities of western Ecuador (Santa Elena Province) are described here. All these shell (carapace and plastron) fossil remains come from the Tablazo Formation and belong to three different lineages of cryptodires ("hidden-necked" turtles). The most abundant remains belong to geoemydids, attributed here to the genus Rhinoclemmys (indeterminate species). Less abundant in occurrence are the kinosternidids, attributed to Kinosternon (indeterminate species), and the first fossil record of chelydrids, Chelydra(indeterminate species), in the entirety of Central and South America.

TL;DR: The presence of fossil reptiles from the mainland of Asia, such as: giant tortoise (Megalochelys sp.), fresh water turtle (Geoemydidae), crocodile (Crocodylus sp.) and the komodo dragon (Varanus kOModoensis) in the Soa Basin of Flores, supports the hypothesis that Wallace's line is not a demarcation line between the reptilian fauna from Asia (Indo-Malayan region) and that from Australia (Austro-malayan region), in the reptiles came to Flores about
Abstract: The presence of fossil reptiles from the mainland of Asia, such as: giant tortoise (Megalochelys sp.), fresh water turtle (Geoemydidae), crocodile (Crocodylus sp.) and the komodo dragon (Varanus komodoensis) in the Soa Basin of Flores, supports the hypothesis that Wallace's line is not a demarcation line between the reptilian fauna from Asia (Indo-Malayan region) and that from Australia (Austro-Malayan region) in the reptiles came to Flores about 1 million years ago, or perhaps earlier (during the Pleistocene), by sweep stake dispersal through swimming or floating. After arrived, they lived in isolated conditions and adapted to a savannah environment. Nevertheless no morphological changes with their Asian mainland ancestors could be found.

TL;DR: A new turtle from the early Eocene of Wutu, Shandong Province, China with a full row of well-developed inframarginal scutes is described, demonstrating that stem testudinoids crossed the Palaeocene–Eocene boundary in their original range.
Abstract: We describe here a new turtle from the early Eocene of Wutu, Shandong Province, China. This turtle with a full row of well-developed inframarginal scutes is assigned to the basalmost testudinoids while stem testudinoids were believed to disappear by the Palaeocene–Eocene boundary. This account shows that stem testudinoids crossed this boundary in their original range. The first comprehensive phylogenetic analysis of stem and modern testudinoids performed here demonstrates that the stem testudinoids, previously placed in the family ‘Lindholmemydidae’, do not form a monophyletic group, and the two major clades of testudinoids (Emydidae and Geoemydidae+Testudinidae) split one from another well before the Palaeocene/Eocene boundary, prior to the Late Cretaceous.

TL;DR: Forty threatened and endangered Malaysian freshwater turtles representing four species in four genera of Geoemydidae destined for the Chinese food market were seized by authorities in Hong Kong in 2001 and transferred to the University of Florida, Gainesville, Florida, U.S.A. to be examined for metazoan parasites.
Abstract: Forty threatened and endangered Malaysian freshwater turtles representing four species in four genera of Geoemydidae (Cuora amboinensis, Heosemys grandis, Orlitia borneensis, Siebenrockiella crassicollis) destined for the Chinese food market were seized by authorities in Hong Kong in 2001 and transferred to the University of Florida, Gainesville, Florida, U.S.A. to be examined for metazoan parasites. The parasites of these turtles were removed, preserved, and tentatively identified. Specimens collected were subsequently transferred to the Laboratory of Parasitology, Department of Wildlife and Fisheries Sciences, Texas AM Meteterakis striatura, Proatractis sp., Trichoskrjabinia malayana, O. linguiformes, and Parapleurogonius brevicecum from H. grandis; Orientatractis...
