Abstract:

The site, discovered in 1995, reveals the s.c. Lozents suite, dated Early Pliocene (Ruscinian), MN 14. Three species of vertebrate (a fish, a reptile and a bird) have been established. One bone fragment (a proximal part of a left humerus, No NMNHS 1644 - holotype) belongs to an undescribed swan. A review of fossil swans and a morphological comparison of the find are presented.
