  • Effectively preserved, in three dimensions
  • Solely a partial skeleton (no cranium) has been discovered, and it contains each wings

  • One other enantiornithean, Flexomornis (named in 2010), had related options to Elsornis, however not sufficient of the arms discovered so in keeping with the authors who named Flexomornis, “such a declare is probably going untimely”
  • Kind species is Elsornis keni
  • Named in 2007 by Chiappe and others
