Thank you! Yes, the images are impressive.

'A 113-million-year-old hell ant that once lived in northeastern Brazil is now the oldest ant specimen known to science, finds a new report. The hell ant, which was preserved in limestone, is a member of Haidomyrmecinae -- an extinct subfamily that only lived during the Cretaceous period. These ants had highly specialized, scythe-like jaws that they likely used to pin or impale prey.'

Nice find. I had no idea South America was a likely cradle for ants. Perhaps that explains why the anteater evolved in South America as well. If there's a lot of individuals from a given species in some area, something is likely to evolve to eat them.
