Like modern vampire bats, they also lived in Central and South America, only in the Pleistocene, almost 654.38 million years ago. In recent years, some human remains have been discovered before they became fossils, which means that they may only have lived hundreds of years ago before they became extinct. Even so, the understanding of Dracula vampire bat is very limited. Recently discovered fossils have played an important role.

Paleontologists found it in a cave on the outskirts of Buenos Aires, Argentina, and it was hidden in sediments during the Pleistocene. They found that this cave is the home of a giant ground sloth, which has certain reference value for us to understand the habits of Dracula's blood-sucking bat. In the past, researchers thought that the main targets of these bats were rodents or mammals such as deer. Now it seems that giant ground sloths such as grinding teeth may also be one of their recipes.

There is also a possible evidence for this speculation, that is, about 10000 years ago, with the gradual extinction of these giant mammals, the number of Dracula vampire bats also decreased, probably because of insufficient food sources. However, in view of the fact that there is only this fossil as evidence at present, researchers can only make preliminary speculation and cannot draw conclusions.
