Great photo-set. Never visited that museum in Ustrzyki.
I liked this comparison between Tertiary and - how to say Czwartorzêd in English, geeee! - Quartiary? - but it may be misleading. While some time ago there was a lot of havoc about 'missing link' Eva,the Australopithecus afarensis, I have learned that already in the Tertiary they stood on two!
