Terrestrial Origin of Viviparity in Mesozoic Marine Reptiles Indicated by Early Triassic Embryonic Fossils
Viviparity in Mesozoic marine reptiles has traditionally been considered an aquatic adaptation. We report a new fossil specimen that strongly contradicts this traditional interpretation. The new specimen contains the oldest fossil embryos of Mesozoic marine reptile that are about 10 million years older than previous such records. The fossil belongs to Chaohusaurus (Reptilia, Ichthyopterygia), w...
متن کاملEcomorphological diversications of Mesozoic marine reptiles: the roles of ecological opportunity and extinction
—Mesozoic marine ecosystems were dominated by several clades of reptiles, including sauropterygians, ichthyosaurs, crocodylomorphs, turtles, and mosasaurs, that repeatedly invaded ocean ecosystems. Previous research has shown that marine reptiles achieved great taxonomic diversity in the Middle Triassic, as they broadly diversified into many feeding modes in the aftermath of the Permo-Triassic ...
متن کاملSome Aspects of Electrolyte Excretion in the Green Turtle, Chelonia Mydas Mydas.
Except for the brief period of egg-laying, five species of turtle are strictly marine: namely, the green turtle (Chelonia mydas), the loggerhead turtle (Caretta carettd), Ridley's turtle (Lepidochelys olivacea), the hawksbill turtle (L. imbricatd) and the leatherback turtle (Dermochelys coriacea). Reptiles in the sea, like marine fish and marine birds, have a high intake of electrolytes; yet, a...
متن کاملA large aberrant stem ichthyosauriform indicating early rise and demise of ichthyosauromorphs in the wake of the end-Permian extinction
Contrary to the fast radiation of most metazoans after the end-Permian mass extinction, it is believed that early marine reptiles evolved slowly during the same time interval. However, emerging discoveries of Early Triassic marine reptiles are questioning this traditional view. Here we present an aberrant basal ichthyosauriform with a hitherto unknown body design that suggests a fast radiation ...
متن کاملMacropredatory ichthyosaur from the Middle Triassic and the origin of modern trophic networks.
The biotic recovery from Earth's most severe extinction event at the Permian-Triassic boundary largely reestablished the preextinction structure of marine trophic networks, with marine reptiles assuming the predator roles. However, the highest trophic level of today's marine ecosystems, i.e., macropredatory tetrapods that forage on prey of similar size to their own, was thus far lacking in the ...
