摘要：

The rock shelter of Tan Zoumaitek, Tassili-n-Ajjer, Central Sahara, Algeria, famous for its paintings of humans and mammals, is found to contain as well several pictures of objects that are most likely medusae. Ii is argued that these can be identified as the afrotropical Limnocnida tanganjicae GUNTHER. The duration of their isolation, after the end of the early Holocene humid period, may be contemporaneous (c. 8000 years) with that of the extant relicts of that species in Mauretania and Chad. These figures are the oldest images of a cnidarian currently known.
