The first Oligocene sea turtle (Pan-Cheloniidae) record of South America
The evolution and occurrence of fossil sea turtles at the Pacific margin of South America is poorly known and restricted to Neogene (Miocene/Pliocene) findings from the Pisco Formation, Peru. Here we report and describe the first record of Oligocene (late Oligocene, ∼24 Ma) Pan-Cheloniidae sea turtle remains of South America. The fossil material corresponds to a single, isolated and well-preser...
متن کاملNew turtle egg fossil from the Upper Cretaceous of the Laiyang Basin, Shandong Province, China.
A new type of turtle egg fossil was established: Emydoolithus laiyangensis oogen. et oosp. nov.. Based on its elliptical morphological shape, rigid eggshells, and eggshell characteristics, it is different from other types of round chelonian egg fossils. It is the second chelonian egg fossil found in Cretaceous in China. This discovery shows the Laiyang ecosystem in Late Cretaceous is more diver...
متن کاملAn early bothremydid (Testudines, Pleurodira) from the Late Cretaceous (Cenomanian) of Utah, North America
BACKGROUND Bothremydidae is a clade of extinct pleurodiran turtles known from the Cretaceous to Paleogene of Africa, Europe, India, Madagascar, and North and South America. The group is most diverse during the Late Cretaceous to Paleogene of Africa. Little is known, however, about the early evolution of the group. METHODS We here figure and describe a fossil turtle from early Late Cretaceous ...
متن کاملComparative bone histology of the turtle shell (carapace and plastron): implications for turtle systematics, functional morphology and turtle origins
The bone histology of the turtle shell is valuable for addressing osteoderm and shell formation, reconstruction of fossil integumentary soft-tissue structures, phylogenetic hypotheses and functional aspects of the turtle shell, with both carapace and plastron showing similar results. Besides intrinsic physiological factors, the shell bones are proposed to be influenced by a mosaic of phylogenet...
متن کاملVertebrates of the Marília Formation (late Maastrichtian) from the Peirópolis Paleontological Site: toward a Better Understanding
The Peirópolis paleontological site (Late Cretaceous, Maastrichtian) in Minas Gerais State, Brazil yielded an important assemblage of fossil vertebrates. The typical occurrence of South American widespread taxa in Peirópolis is important for correlation between the Brazilian Bauru Basin and Argentinean Late Cretaceous basins. The fishes, turtles, anuran, crocodilians and dinosaurs known from Pe...
