Scientists exploring a cave on a Caribbean island made a surprising discovery: ancient bees unlike the ones we know today. For the first time, paleontologists found fossil evidence of burrowing bees nesting inside the bones of ancient animals. This finding sheds light on the diverse behaviors of bees, according to researcher Lazaro Viñola Lopez.
Viñola Lopez, a doctoral student at the Florida Museum of Natural History, wasn’t searching for insects when he and his team excavated fossils in Cueva de Mono, located in the Dominican Republic. They were studying vertebrates related to the late Quaternary extinctions caused by climate change and human activity. What they stumbled upon were thousands of fossils belonging to an extinct rodent known as hutia.
While examining the hutia remains, Viñola Lopez noticed an odd smoothness on one of the jawbones. Initially, he thought these features might be linked to wasps, as he had worked with dinosaur fossils before. However, he later realized that the remains were actually used by a species of burrowing bee, named Osnidum almontei, that lived many thousands of years ago.
These ancient bees were unique. While many bees are sociable and build visible nests, most species are solitary, and these bees took nesting to another level. They used chambers in bones, a behavior not seen in other known bee species. The cave likely served as a nesting site after being used by ancient barn owls, who might have left hutia remains behind either as leftover meals or droppings.
The researchers learned that cave environments might provide essential nesting materials for these bees. By studying these findings, scientists are more cautious about how they handle fossils from such caves. Viñola Lopez mentioned that this discovery has shifted their approach to fossil cleaning, allowing them to preserve any hidden traces of ancient insect behavior.
As for the ancient cave bees, they are just one part of the ongoing research. The team is excited to uncover even more fossils, which could include previously unknown species of mammals, reptiles, and birds.
Recent studies show that solitary nesting behaviors in bees might be more common than previously thought. This discovery enriches our understanding of the natural world and reminds us of the complex ecosystems that existed long before us. For today’s bees, these ancient findings are a valuable reminder of adaptation and survival.
