    Carbon 14 dating dinosaur bones

    Dinosaur and Dinosaur-Layer Creatures: The dinosaurs and other Mesozoic creatures that have yielded their biological material are hadrosaur, titanosaur, ornithomimosaur [ostrich-like dinosaurs], mosasaur, [bird-like] .As you view the exciting scientific discoveries below in this chronological catalog, please feel free to listen to Real Science Radio co-hosts Fred Williams and Bob Enyart observe their annual tradition of presenting dinosaur soft tissue and other amazing discoveries including short-lived left-handed amino acids, DNA, and Carbon 14, all in bones and other specimens from dinosaur-layer Mesozoic and even deeper strata. Clockwise from top left: Microraptor gui (a winged theropod), Apatosaurus louisae (a giant sauropod), Edmontosaurus regalis (a duck-billed ornithopod), Triceratops horridus (a horned ceratopsian), Stegosaurus stenops (a plated stegosaur), Pinacosaurus grangeri (an armored ankylosaur) Dinosaurs are a diverse group of reptiles of the clade Dinosauria that first appeared during the Triassic period.Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago.Real Science Radio hosts Bob Enyart and Fred Williams had predicted on air and in writing at rsr.org/predictions that: - Dinosaur soft tissue will be found not only in rare circumstances, but rather easily, i.e., when looked for. The journal reported original tissue in six of eight dinosaur bones investigated, leading to the conclusion that "preservation is more common than previously thought." And: - Original dinosaur and other biological tissue will be found largely independent of the claimed age of the fossil."beard worms" that are allegedly 530 million years old!

    Biological Material Found: As of 2017, in fossils from dinosaur-layer and deeper strata, researchers have discovered flexible and transparent blood vessels, red blood cells, many various proteins including beta-keratin, the microtubule building block tubulin, collagen, the cytoskeleton components actin, tropomyosin, and the related motor protein myosin, and hemoglobin, bone maintenance osteocyte cells, DNA-related histone proteins, and powerful evidence for DNA including positive results from multiple double-helix tests.Diamond is the hardest substance known, so its interior should be very resistant to contamination.Diamond requires very high pressure to form—pressure found naturally on earth only deep below the surface.Even so, scientists have found intact soft tissue in dinosaur bones before.The most famous case dates to 2005, when Mary Schweitzer of North Carolina State University found collagen fibers in the fossilized leg bone of a Tyrannosaurus rex.
