of Science (Prirodoslovno-matematički Fakultet) at the University of Zagreb. He was the founder and president of the Speleological Association of Croatia. During an expedition to the "Strašna peć" cave in 1953 (English: "the horrible stove"), Malez wrote: "We were muddy, dirty, bloody as well, since we scraped on the stone blocks and stalactites during the wriggling and crawling. But, we didn't feel any regret. We were inebriated with the beauty we saw inside that place. We have experienced the harmony of the natural creation and have realised that it is indeed "horrible", as its name is telling us..". For his scientific contributions in 1966 he received the "Ruđer Bošković" award. Malez left over 430 original scientific, expert and popular-scientific papers on quaternary geology, tertiary and quaternary vertebrates, fossil man and his material cultures, and papers about Palaeolithic and Mesolithic archaeology and speleology. Some of his main research sites included Vindija, Istrian sites Šandalja, Oporovina, the Romualdova cave, Pećina on the Gradina hills, the Vergotinova cave, Klanjčeva peć, Podosojna peć, Loza and the well known cave Veternica, on the south facing hill slopes northwest of the Croatian capital Zagreb. In Romualdova cave between 1961 and 1962, Malez excavated five probes in the cave and found the bones of Pleistocene animals, including the cave bear, cave lion, leopard, cave hyena, wild horse, big deer, snow hare, and others. Malez carried out anatomical-morphological analyses and studies of geological stratigraphy dating, the appearance of ice wedges and the development of river terraces. He paid special attention to the levels of the Gravettien culture in the Šandalja cave near the city of Pula in Croatia. On the evidence of hearthstones and material cultures, Malez found the presence of the early man Homo Erectus in the Šandalja cave dated to approximately 900,000 years of age. The Vindija Cave site was first excavated in the first half of the 20th century, and more extensively excavated between 1974 and 1986 by Malez. Numerous archaeological and faunal remains have been found, with over 100 hominid discoveries. Co-authoring with Erich Thenius Malez describes a new species, from the Perissodactyla Order, Amynodontidae Family: Cadurcotherium rakoveci, whose fragments were found in Ugljevik, Croatia within brown coal, dated to the Upper Oligocene (or lower Miocene). This species is the most evolved of the part of the Order that migrated to Europe from Asia in the beginning of the Oligocene. During deep-sea trawling by
