Cenomanian birds

Alexornis was a genus of enantiornithine birds from the La Bocana Roja Formation of Baja California, Mexico. This geological formation has been dated to the late Cretaceous period, and more specifically to the Cenomanian and Turonian ages, about 93.6 mya. The type and only known species is Alexornis antecedens. The scientific name as a whole means "Alex's ancestral bird"; Alexornis from the given name of ornithologist Alexander Wetmore + Ancient Greek ornis, "bird", and antecedens, Latin for "going before" or "ancestral".

Pasquiaornis is a prehistoric seabird genus of the Hesperornithes. It lived in the Late Cretaceous, during the late Cenomanian between 95 and 93 million years ago in North America. Two species, P. hardiei and P. tankei, were described in 1997 by Tim Tokaryk, Stephen Cumbaa and John Storer.

Elektorornis () is an extinct genus of enantiornithean bird from the Late Cretaceous of Myanmar. The genus contains a single species, Elektorornis chenguangi, known from a partial hindlimb and a small amount of wing plumage preserved in amber. In life, it would have been slightly smaller than a sparrow and possibly used its characteristically elongated middle toe to probe for food. Elektorornis chenguangi is the first bird species described from remains found in Burmese amber, although other undiagnostic enantiornithean specimens have previously been found.
