A constructionworker has found fossils of what has been described as a “whale-like mammal" during work on a new dumpingsite for householdwaste near the northwestern Bulgarian city of Vidin.
The whalefossils were discovered by MiroslavPankov, who drives a truck, back in the fall of 2013, in an area known as Kozi Garbini (“Goat Backs"). However, they have made their way to the Bulgarian scientists just now, reports RadioVidin.
“I was driving the truck down a steep section, some very dangerous terrain. I was driving slowly, and I noticed a peculiar object in the soil. I stopped and went to check what it was. At first, I thought it was a strange stone but then I figured out it was a bone. I dug up a little and found more bones. I brought them home, and I had forgotten about them until recently when I was cleaning up my apartment and found them. I took them to the [Vidin] Museum," Pankov says, telling the story of his discovery.
“I hope they will be made part of the Museumcollection. I watch a lot of documentaries on TV, and that’s why the bones made an impression on me. A lot of people must have passed by them but didn’t pay attention. I am glad I found them, and I am glad our region yields such finds," he adds.
“The conclusion of the [National Museum of Natural History] in Sofia is that these are the bones of a whale which lived about 10 million years ago. They should be put on display," says the archaeologist from the Vidin Regional Museum of History while praising Pankov, first, for taking interest in what he found, and, second, for bringing his finds to the Museum.

Assist. Prof. Latinka Hristova also thinks it is a great idea for the Vidin Museum to set up a paleontologyexhibit with the newly found whale fossils, and adds that the National Museum of Natural History in Sofia is ready to provide for the future exhibitionfossils of other mammals from the whale family discovered over the years near the town of Florentin, Vidin District, on the Danube River.
“The discovery consists of several vertebrae and a pelvisbone. The bones are from a whale-like mammal, and date back to the Neogene (app. 23 – 2.6 million years ago). During the Miocene (app. 23 – 5.3 million years ago) the region of Vidin was part of the ParatethysOcean. This was a shallow sea which formed as a result of its splitting from the Tethys Ocean because of the formation of the mountain range of the Alps. Several times the Paratethys was fully isolated losing its connection with the Tethys and its successors – the Mediterranean or the Indian Ocean. During the different geologic ages it covered varying areas of contemporary Europe – from the northern slopes of the Alps in Germany and Austria all the way to the Aral Sea. It had its greatest area during the Oligocene (34 – 23 million years ago), while in the Late Miocene (23 – 5.3 million years ago) it lost its connection with the world ocean for the last time, and gradually disappeared. The climate was warm, subtropical, and when it had the normal salinity of ocean water this ocean was inhabited by a large number of animal species not unlike the modern-day warm seas and oceans: corals, snails, mollusks, echinoderms, fish. The diversity of marine mammals was also great – it features almost all groups such as seals, dolphins, toothed whales and baleen whales," explains Latinka Hristova from the National Museum of Natural History in Sofia.
“Our Museum does not have the money to buy out the new find so I have recommended that the VidinMuseum buy it, and set up an exhibition. There are many interesting archaeologicalfinds in Vidin, and it would be great [for the Museum] to also have this paleontology collection. This will provide for a more detailed historicalpicture," she adds.
Paleontology in Bulgaria started to develop as a separate discipline in the second half of the 20th century. Consistent with the type of the specific fossil finds, Bulgarian paleontology has been focused mostly on the study of prehistoricmammals (such as elephants, rhinoceroses, whales) of which numerous fossildeposits have been found, and paleo-ornithology, the study of prehistoric birds. There have been few discoveries of fossils from dinosaurs, fish, and amphibians, and, respectively, little academic effort dedicated to those fields. So far only two dinosaur species have been proven to have lived on Bulgaria‘s territory – an ornithomimosaur species and a hadrosaurid species, as well as the aquatic lizard species of mosasaurus.
