12 Ιουλ 2019 · To the best of our knowledge, 2P imaging microscopy of the living human eye has never been performed before. In this work we present a new compact clinically-adapted 2P microscope to record...
Microraptor was a very small, feathered dinosaur with wings on its legs as well as its arms. As a member of the dromaeosaur group, it was related to the well-known dinosaur, Velociraptor . Of all the dromaeosaurs, we have the most fossils for Microraptor .
7 Μαΐ 2021 · Such sensory innovations are unknown in nonavialan theropod dinosaurs and are poorly characterized on the line that leads to birds. We investigate morphofunctional proxies of vision and hearing in living and extinct theropods and demonstrate deep evolutionary divergences of sensory modalities.
16 Ιουν 2011 · Abstract. Here we introduce a database of calibrated natural images publicly available through an easy-to-use web interface. Using a Nikon D70 digital SLR camera, we acquired about six-megapixel images of Okavango Delta of Botswana, a tropical savanna habitat similar to where the human eye is thought to have evolved.
6 Δεκ 2000 · Now Chinese paleontologists describe the smallest, at least of the dinosaurs: a Microraptor that would have easily rested in the palm of your hand. The lightweight, feathered creature reinforces the theory that birds evolved from dinosaurs.
