متن کاملVase-shaped Microfossils from the Neoproterozoic Chuar Group, Grand Canyon: a Classification Guided by Modern Testate Amoebae
Vase-shaped microfossil (VSM) assemblages from early diagenetic carbonate nodules in .742 6 6 Ma black shales of the Chuar Group, Grand Canyon, provide evidence for affinities with testate amoebae. Not only are VSMs exceptionally preserved in Chuar rocks, they exhibit a much higher degree of morphological diversity than was previously known. Using the taxonomy of modern testate amoebae as a gui...
