Do you have any pictures of saiga antelope?
I’ve managed to find a few pictures, there’s some nice anatomical illustrations in: ‘Murie, J. 1870. On the saiga antelope, Saiga tatarica (Pall.). Proceedings of the Zoological Society, London 1870:451-503.’ The 3d scans at Digimorph are great:
The paper describing the Saiga’s weird nose is very interesting: ‘Case studies in novel narial anatomy: 3. Structure and function of the nasal cavity of saiga (Artiodactyla: Bovidae: Saiga tatarica)’ (PDF)
