About Rhynchaeites
Rhynchaeites (Greek for "beak fossil") is an extinct genus of wading bird, a stem-group threshkiornithid, which lived in Europe and North America during the Eocene epoch. The genus contains three species, R. messelensis, R. litoralis and R. mcfaddeni. It is one of the oldest members of the ibis family known from fossil remains.
