Eldonia is an extinct soft-bodied cambroernid animal of unknown affinity,[3] best known from the Fossil Ridge outcrops of the Burgess Shale, particularly in the 'Great Eldonia layer' in the Walcott Quarry.[4] In addition to the 550 collected by Walcott,[5] 224 specimens of Eldonia are known from the Greater Phyllopod bed, where they comprise 0.43% of the community.[6] Species also occur in the Chengjiang biota,[2] Siberia,[7] and in Upper Ordovician strata of Morocco.
A specimen from the Lower Ordovician Madaoyu Formation in Hunan, South China, can be interpreted as the incomplete body of Eldonia or the similar animal. However, its annulation, the structure of the intestine and the shape of the body are more similar to those of Ottoia.[8]
