The piece containing these inclusions is absolutely loaded with different arthropods, but the most spectacular inclusions are those of a swarm of 11 extinct Leptomyrmex ants: there are 9 complete and 2 incomplete individuals, averaging 3.5mm in body length. In a lighthearted interpretation, it appears as though the duo in this image are performing some acrobatic act, while half of another individual gives audience!


Other prominent inclusions consist of a twig (7mm), spider (2mm), formicine ant (3mm), two muscoid flies (1.5mm), two nematoceran flies (possible chironomid at 1mm, heavily decomposed mycetophilid at 3mm), and numerous enhydros.
