Formica alsatica

紹介

Formica alsatica is an extinct ant species known only from fossil specimens preserved in Oligocene amber deposits from the Upper Rhine Graben of Kleinkems in what is now France . This species lived approximately 30+ million years ago during the late Eocene to early Oligocene period. Only fossilized queen specimens have been documented, with no worker casts known from the fossil record. As a fossil species, Formica alsatica cannot be kept in captivity - there are no living specimens to collect or maintain.
