The oldest ant ever discovered found fossilized in Brazil

SMRTR summary

A 113-million-year-old hell ant fossil discovered in Brazil is now the oldest known ant specimen. Found in limestone, this extinct Cretaceous-era species had specialized scythe-like jaws for hunting prey. The discovery challenges previous understanding of ant evolution and distribution, showing ants were widely spread and diverse early on. The fossil's remarkably preserved features, including unique forward-facing mandibles, suggest sophisticated predatory strategies had already evolved in these ancient ants.
