A first attempt has been made to systematically present the achievements of several archaeozoological fields in Bulgaria: archaeomalacology, archaeoichthyology, archaeoherpetology, archaeornithology, and archaeomammalogy. The main results and some of the more significant studies in each of these fields are presented. In summary, archaeozoological studies began in the first decade of the 20th century. A list of established authors of archaeozoological publications in Bulgaria has been compiled. Of the identified species, four species of birds and six species of mammals have disappeared from the modern fauna of the country. Two species have completely disappeared globally.
Zlatozar Boev (Tue,) studied this question.
