The paper summarizes numerous scattered data from the last 120 years on the former distribution of the brown bear (Ursus arctos) in Bulgaria. Data from 52 (13 fossil and 39 subfossil) sites (from the ...Middle Pleistocene to the 19th century AD) are presented. The brown bear former distribution was much wider than the present occurrence. The species range covered the whole territory of the country, including mountain regions, as well as vast lowland and plain landscapes. The geographical, altitudinal and chronological distribution are presented and analyzed. The record from the Kozarnika Cave (1.000,000–700,000 years BP) is one of the earliest records of this species in Europe. About 73% of the localities are situated between 100 and 500 m a. s. l. Twelve sites contain Paleolithic finds, one Mesolithic, 14 Neolithic, six Chalcolithic, five from the Bronze Age, and two from the Iron Age. The remaining 12 subrecent sites are dated to the last ca. 2,400 years. Most of the species findings came from archeological sites – prehistoric and ancient settlements. The distribution of Ursus arctos once covered the entire territory of the country, including the vast regions such as Ludogorie, Dobruja, the Danube Lowland, the Upper Thracian Lowland, as well as the Sakar, Strandja, Sredna Gora, and the Predbalkan Mts.
The paper summarizes all scattered data from the last 116 years on the distribution of the Late Pleistocene cave hyena in Bulgaria, a part of them unpublished. Data from 24 fossil sites (Middle ...Pleistocene – Late Pleistocene) in the country are presented. The fossil record in Bulgaria proves the wide distribution of the species in the karst areas of the low-mountain regions of the country. Its Pleistocene localities are concentrated in the Predbalkan Mts. (83%), Strandja Mts. (8%), Western Rhodopes Mts. (4%) and southern Dobruja Plain (4%). They are situated at the altitudes between 136 and 1250 m a.s.l., about 75% of them at 136–400 m a. s. l. All (except one) Bulgarian sites represent former human dwellings, which indicates competition between man and this carnivore for the cave spaces.
An observation of a flock of 30 birds on 26 August 2020 on the coast of the Studen Kladenets Reservoir is discussed in the light of the species migration and conservation.

A total of 9 taxa of 6 domestic forms and 3 wild species of animals have been identified, among them wild boar, red deer and roe deer. All finds are dated Middle Ages (10th – 13th century A. D.).

The paper presents first find (a cervical vertebra – atlas) of Strix nebulosa in the Late Pleistocene of CN Bulgaria from the Devetashka Cave (ca. 70 000 BP). It is the first record on the Balkan ...Peninsula, tenth and the southernmost record of the Great Grey Owl in Europe and the Palearctic.
A total of 86 bones and bone fragments of wild and domestic mammals collected in the Late Antiquity military settlement near Barkach village (Pleven Region, CN Bulgaria) have been identified as 9 ...species of 4 orders. Most numerous are the remains of Donkey and the Red deer. The record of the Fallow deer proves the species occurrence in the Late Antiquity in the North Bulgaria.

Although the Collared Dove appeared in Bulgaria at 17-18th century, the subfossil record of the species in the country is rather scant. Only five Late Holocene sites contain bone remains (88 bones of ...9 individuals), but all of them remained imprecisely dated. Some of the sites could be of older (possibly: Early Medieval Ages) age. All sites are situated in the NE Bulgaria and represent former feeding places of Eagle owls (Bubo bubo).

The paper summarizes numerous scattered data on the former distribution of the Mediterranean monk seal (Monachus monachus) along the western Black Sea coast and the lower Danube bank in Bulgaria. ...Data on 25 sites of historical (last two centuries), two sites of subfossil, and one site of fossil records are presented (23 from the Black Sea coast, two from the Danube). Four stuffed skins, two skulls and two subfossil limb bones are kept in three Bulgarian museum collections. The latest record of the monk seal in Bulgaria was documented on 8 December 1996.
The paper summarizes and evaluates all scattered and scanty data on the fossil and subfossil records of reptiles from Bulgaria. A complete list of the 72 localities and the taxonomic composition and ...kind of reptilian findings are presented for the first time. Data cover at least 98 taxa (25 identified up to species level) of 26 genera, 22 families and 6 orders at least. Chronostratigraphically they range from the Kimmeridgian (Late Jurrasic) to the Late Holocene (subrecent), i. e. last 157.3 Ma. Two families (Varanidae and Elapidae) and one subfamily (Lygosominae) of the skinks today include only representatives of exotic distribution. About one fifth of all taxa are fossil. Three of the fossil taxa are described as new to the science. Apart from herpetologists from Bulgaria, experts from Poland and Germany have contributed most to exploration of fossil and subfossil reptiles in the country.
