Desmodus draculae, also named the giant vampire bat, once lived from Mexico to Argentina. It was 30% larger than the common vampire bat. It was first noted in 1965 after Omar J. Linares found a fossil of it in Cueva del Guácharo in Venezuela. He noted it in a 1968 report. In 1988, it was formally listed by science. Not much is known about the giant vampire bat other than fossil evidence of skulls, a humerus, and teeth. Scientists theorize that it fed on megafauna in the Pleistocene into the early Holocene. When North and South America connected in present day Panama during what is referred to as the Quaternary extinction event. Once the megafauna died out, scientists think the giant vampire bats struggled to adjust to smaller sized prey. The most recent giant vampire bat bone, a canine tooth, found in Argentina dated to around 1650 AD. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The giant vampire bat would probably not be a good candidate. Most of the specimens of this bat are fossils, but the canine tooth dating to 1650 could possibly still hold viable DNA. If the giant vampire bat was ever brought back from extinction, would it be able to survive?
