Important difference is also in stratigraphy, as E. loricatus is middle albian species, while E. barroisi lived during upper Albian zone of Dipoloceras cristatum. There is a gap between their occurrence during the zone of Dimorphoplites biplicatus ammonite zone, during which, the only member of this genus was E. lautus.
