Stoycho Vassilev Breskovski  () (December 25, 1934, Granit, Stara Zagora Province, Bulgaria – January 15, 2004, Sofia, Bulgaria) was a Bulgarian paleontologist.

Biography

Stoycho Breskovski was the only son of educators Vassil Stoychev Breskovski (1902 - 1978) and Paraskeva () Breskovska (1906 - 1988). After receiving his primary and secondary education in Plovdiv, he studied geology at Sofia University and graduated in 1958. Then, he took active part in Bulgarian geological survey and in the preparation of the geologic map of Bulgaria at scale of 1:200,000. Later Dr. Breskovski was noted for his research on Lower Cretaceous, Barremian fauna. He was also credited for discovering, identifying and discerning several families, subfamilies, genera and species of ammonites.

From 1974 to 1995 Breskovski had been research associate and curator of the paleontology collection at the  National Museum of Natural History in Sofia. He contributed to the collections at the natural history museums in the Bulgarian cities of Elena, Rousse, Razgrad, and Shumen. In later age he tried to reconcile his various hobbies of  collecting stamps, pocket calendars, phillumeny and philately with science. His older sister, Vesselina Breskovska, was professor of mineralogy, dean and vice rector at Sofia University. He was survived by his wife of 42 years and fellow paleontologist,  Nona Motekova, a son and a daughter, a granddaughter and a grandson, and a siamese cat.

Honors
