Data from: “Kimberella from the terminal Ediacaran Shibantan limestone, South China: the persistence of bilaterians during the White Sea-Nama transition”

However, this genus has a very limited temporal and spatial distribution, with previously known occurrences mainly from siliciclastic rocks in the White Sea assemblage (~560–550 Ma) from Russia and South Australia. Here we report a complete Kimberella specimen and a possibly related resting trace from limestone of the terminal Ediacaran Shibantan Member (ca. 550–543 Ma), Dengying Formation, in the Yangtze Gorges area of South China.

The new fossils represent the youngest known occurrence of Kimberella, and the first record of this genus from carbonate rocks, expanding its known spatial and environmental distributions. Integrated with previously reported Dickinsonia and complex trace fossils in the same and adjacent horizons, Shibantan biota offers an opportunity to test the biotic replacement hypothesis to account for the decline of the White Sea assemblage.
