The above photo is showing an ant specimen, Haidomyrmex scimitarus, in amber dating to the Cretaceous period. It is awesome. I mean look at this thing:
These photos, from a paper by Phillip Barden and David Grimaldi at AMNH published back in September (although retrieved from Myrmecos), show what appears to be some kind of trap jaw ant, but one distinctly different from the extant Odontomachus or Anochetus.
This finding is also special to me, as I was aware of it before its publication – Phillip Barden showed me the drawing my last day at AMNH for my REU in August. With specimens like this out there, I would love to go on an entomological amber excavation someday!
