A Remarkable Discovery in the Dominican Republic

Scientists have made an astonishing find on a Caribbean island: a tiny, 16-million-year-old ant fossil perfectly preserved in amber! This ancient gem represents the very first dirt ant species, known as Basiceros enana, discovered in the Caribbean.

The Size and Significance of Basiceros enana

Measuring just over 5 millimeters, Basiceros enana may be small, but it packs a big punch in the scientific community. This extinct species is notably smaller than its modern-day relatives, which can reach up to 9 millimeters. Despite its size, the fossil provides critical insights into the history of dirt ants, suggesting they once thrived in the Caribbean before going extinct between 23 and 5.3 million years ago.

What Makes Amber So Special?

Amber, the fossilized tree resin, is a treasure trove for paleontologists. It preserves entire organisms in incredible detail, allowing scientists to gather valuable data even from the smallest specimens. This discovery is akin to unearthing a diamond, according to Gianpiero Fiorentino, co-author of the study from the New Jersey Institute of Technology.

Revamping Our Understanding of Evolution

Previously, all known Basiceros ants were found in Central and South America, making this Caribbean finding revolutionary. It raises intriguing questions about the evolutionary history of these ants and indicates they had established a presence on the islands long ago.
