Frontiers in Palaeontology Early Vertebrate Evolution
Debate over the origin and evolution of vertebrates has occupied biologists and palaeontologists alike for centuries. This debate has been refined by molecular phylogenetics, which has resolved the place of vertebrates among their invertebrate chordate relatives, and that of chordates among their deuterostome relatives. The origin of vertebrates is characterized by wide-ranging genomic, embryol...
متن کاملMolecular Palaeontology
In the broadest possible sense, molecular palaeontology might encompass any and all chemical traces left by onceliving organismsorby their life processes.Thiswould cover fields ranging from isotope geochemistry and biomineralization to molecular biology. However, in a more restricted sense, molecular palaeontology is the study of complex organic molecules made by once-living organisms. In some ...
متن کاملPalaeontology: The New Conservative
Cambrian Orsten-type fossils have yielded specimens with a uniquely detailed morphology from the early stages of animal evolution. A newly discovered crustacean larva illustrates how morphology and lifestyle over half a billion years ago closely resembled those of extant relatives.
متن کاملTrace element concentrations in teeth e a modern Idaho baseline with implications for archeometry, forensics, and palaeontology
Concentrations of 69 minor and trace elements were measured in situ using laser ablation inductivelycoupled plasma mass spectrometry in multiple teeth of modern herbivores (Cervus elaphus, Odocoileus hemionus, Odocoileus virginianus; n 1⁄4 52), omnivores (Ursus americanus; n 1⁄4 56), and carnivores (Felis concolor; n 1⁄4 33; Canis lupus; n 1⁄4 4) from Idaho, USA. On each tooth, two to five anal...
متن کاملPalaeontology: Turtles in Transition
One of the major remaining gaps in the vertebrate fossil record concerns the origin of turtles. The enigmatic little reptile Eunotosaurus could represent an important transitional form, as it has a rudimentary shell that resembles the turtle carapace.
