Here is a Cretaceous drama (including both original players) captured in amber and perfectly preserved for 99 million years.  A predatory “hell ant” (haidomyrmecine) was grasping a proto-cockroach (Caputoraptor elegans) in its strange vertical mandibles when a dollop of sap preserved both creatures in resin.  Because it was so well preserved, we can see how the hell ant’s mouth parts are completely different from those of modern ants. Today’s ants all have horizontal side to side scissor-like mandibles.  The ancient hell ant has scythelike vertical mandibles which meet up with horn like appendages on its forehead (like a platybelodon…if its upper tusks came out above its eyes).

The ant was found in a piece of amber from modern Myanmar and gives us a precious window into the lives of ancient ants (which were seemingly as widespread in the age of the dinosaurs as they are now, yet were also completely different than they are now).  The first ants evolved during the Jurassic (170 million years ago) so the hell ant is nearly as far removed from its first ancestors as today’s ants are from it.  Sometimes it seems like the way we picture the world–an empire belonging to dinosaurs, Andrewsarchus, or humans–must be ridiculous to ants.  To them we macrofauna must seem like ludicrous obscene monsters who dwell in a different world and are doomed to disappear in the immediate future (the same as Kardassians appear to us normal people).
