He was the first man ever to use the x-ray to analyze the fossil bones. He participated in several scientific gatherings in Europe and gave a significant contribution to the Croatian geological science. He was also the founder of the Geological commision for the Kingdom of Croatia and Slavonia, which was a predecessor of the Geological Institute in Zagreb today. All in all, he published 237 works. He was named the court counsellor, honorary citizen of Zagreb, Krapina and Karlovac, honorary doctor at the Zagreb University, honorary member of the Choir of Croatian doctors, and the Croatian Natural History Society. After his death in 1936 up until today, many scientific gatherings dedicated to his greatest work have been held.

First and foremost, he was a tireless museum worker, an expert and an all-round scientist, as proved by his personality and entire scientific opus. The caring for his work is noticeable in the collection itself, his library, his works and scientific bonds he had with experts and institutions worldwide. He was one of the best paleontologist - his knowledge preceeding the time in which he lived. The amount of energy, consistency and careful attention he had while studying the remnants was incredible, as was the relentnesness and versatility of his work.
