The following species are known:^[2][3]

• E. anglicus Woodward, 1901 - mid-late Cenomanian of England (English Chalk)^[4]
• E. syriacus Woodward, 1901 - Santonian of Lebanon (Sahel Alma)
• E. villosus von der Marck, 1863 (type species) - Campanian of Germany (Baumberge Formation)

Its taxonomic affinity remains uncertain; it was initially classified as an early halosaur in the order Notacanthiformes, and continues to be treated as such by some authorities. However, other studies have found it to be an elopomorph related to the common ancestor of Anguilliformes and Notacanthiformes,^[5][6][7] or even an early anguilliform itself.^[8]
