Janavis

Janavis (from the Roman god Janus and the Latin avis for bird) is an extinct toothed bird, belonging to the Ichthyornithes, from the Late Cretaceous of Belgium. The genus has one named species, Janavis finalidens (from Latin finalis, meaning ending or final, and dens, for tooth) that was discovered in the 1990s, reported in 2002, and described in 2022. Recovered almost simultaneously from the same area and age as Asteriornis maastrichtensis, then the oldest known modern bird, it provides information on the evolution and divergence of basal and modern birds, especially on the evolutionary modifications of bird skulls.
