The pre-Cenozoic bryophyte fossil record is significantly sparser than that of vascular plants or Cenozoic bryophytes. This situation has been traditionally attributed to a hypothesized low preservation potential of the plants. However, instances of excellent pre-Cenozoic bryophyte preservation and the results of experiments simulating fossilization contradict this traditional interpretation, s...

Over the past decades, abundant and well-preserved vertebrate fossils, known as Urho Pterosaur Fauna, have been recovered from Lower Cretaceous Tugulu Group in Junggar Basin, Xinjiang, NW China. Excavated materials belong to pterosaur, plesiosaur, dinosaur, crocodylomorph, turtle taxa. As such, they provide key insights into evolutionary history of several critical groups Early Cretaceous. The ...
