During one of Leonid Rosca’s expeditions to explore his homeland, a lump of rock stuck into his eye. In fact, it was not the rock itself, but the form of its surface. He figured out a head, a beak, eyes, bones, wings. Leonid Rosca had discovered a petrified 150-million-year-old Pterodaktyl and thus by far the oldest remains of an animal ever found in the Republic of Moldova.
