  1. That looks AWFUL. How could anything think that's plausible, even the artist?

  2. I know that in their 1986 Baryonyx description, Charig & Milner suggested that Baryonyx may have been quadrupedal (primarily based upon how robust the arm bones were); though they abandoned that notion in their 1997 osteology (at least, I'm pretty sure they did).

  3. A parte il caso del Baryonyx, Dong Zhiming aveva proposto una postura quadrupede per Xuanhanosaurus qilixiaensis Dong, 1984 [Dong, Z. (1984). "A new theropod dinosaur from the Middle Jurassic of Sichuan Basin". Vertebrata PalAsiatica 22(3):213-218].
    Il paleontologo cinese era assai eclettico - oppure di "manica larga" - nel suo pensiero:
    > ricordo il "Dilophosaurus" sinensis con becco [intervista su National Geographic, vol. 183, n.1, jan. 1993];
    > oppure il Nanshinugosaurus brevispinus come titanosauride o stegosauride [Zhiming Dong, "Dinosaurs from the Cretaceous of South China, in Mesozoic and Cenozoic Red Beds of South China Selected Papers from the "Cretaceous-Tertiary Workshop,"
    Nanxiong, Guangdong Province, Institute of Vertebrate Paleontology, Paleoanthropology
    & Nanjing Institute of Paleontology Science Press, 1979, pp. 342-350].
