Abstract
We describe an exceptionally well-preserved partial skeleton of a new bird from the early Eocene Fur Formation of Denmark. Like other fossils from these marine deposits, the partial skeleton is three-dimensionally preserved and articulated. This new Danish specimen consists of a skull, vertebral column, ribs, pelvis, and hindlimbs. Concerning characters of the pelvis, tibiotarsus and tarsometatarsus, the new fossil bears morphological affinities to charadriiform birds (shorebirds and relatives). A phylogenetic analysis of higher neomithine (modern birds) taxa also supports a close relationship between the new specimen and modern Charadriiformes. The morphologies of the skull and vertebrae, however, distinguish the new fossil from all recent charadriiform families.
