"Mesozoic on the Fourth Floor" is a book about smart, clever and, one might even say, strong people! Imagine that a real time portal has appeared in your apartment. Now your whole family is free to go back in time, the very old past, all the way back to the Mesozoic. And Mesozoic animals - dinosaurs - can end up in your home, eat your soup, overcome burglars... Do you think this is fantastic? And here and there - this is a fun story by Stanislav Solovinsky, which we sincerely recommend to be read by the whole family. The publication was printed with funds from an institutional support grant.
