Scientists have found amber containing perfectly-preserved 95-million-year-old bugs. From Wired Science:
Suspended in the stream of time were ancestors of modern spiders, wasps and ferns, but the prize is a wingless ant (above) that challenges current notions about the origins of that globe-spanning insect family.
The amber, which is formed when plant resin fossilizes, preserving flora and fauna trapped within, was found in what is now northwest Ethiopia. Ninety-five million years ago, it was part of a disintegrating Gondwana, one of two vast land masses that spawned the seven modern continents.
While it will take years to interpret the ecological tales trapped in the new amber, one important story is already suggested. Inside the Ethiopian amber is an ant that looks nothing like ants found in Cretaceous amber from France and Burma. Those deposits had placed the origin of ants in Laurasia. That’s no longer certain.
