Most dedicated creationist advocates will already be familiar with the mental gymnastics required to assert that a coelacanth allegedly remaining unchanged for tens of millions of years somehow disproves evolution, therefore life must have been magically created ex nihilo just a few thousand years ago.
Now they have a new specimen to test their contortions even further: a beautifully preserved 113-million-year-old ant fossil from Brazil—the oldest ant fossil discovered to date. Remarkably, by 113 million years ago, this now-extinct species was already highly specialised as a predator, equipped with distinctive scythe-like mandibles. These formidable features have earned it the informal nickname "hell ant."
The exquisitely preserved limestone fossil clearly reveals detailed wings and wing veins, characteristic of the insect order Hymenoptera, confirming ants' close evolutionary relationship with wasps and bees. Since wings are typically absent in worker ants, the presence of fully developed wings strongly suggests that this specimen represents a reproductive female—likely a queen.
This remarkable ant fossil was identified within a collection originating from the Crato Formation in northern Brazil, housed in the Museu de Zoologia da Universidade de São Paulo. The Crato limestone was deposited in a shallow lake environment approximately 113 million years ago during the Early Cretaceous period, at a time when the ancient southern supercontinent Gondwana had not yet fully separated into what would become modern-day Africa and South America.
