Info
Ichthyornis dispar (Marsh, 1872) [= Colonosaurus mudgei (Marsh, 1872) including Ichthyornis agilis (Marsh, 1873); Graculavus agilis (Marsh, 1873); Ichthyornis anceps (Marsh, 1872);Graculavus anceps (Marsh, 1872); Ichthyornis victor (Marsh, 1876); Ichthyornis validus (Marsh, 1880); Ichthyornis antecessor (Wetmore, 1962); Plegadornis antecessor (Wetmore, 1962); Angelinornis antecessor (Wetmore, 1962)
Ichthyornis victor was named by Marsh, (1876) and differentiated from the holotype of Ichthyornis dispar (YPM 1450) as being one-third larger than that species (Marsh, 1876). Referred specimens: The majority of YPM specimens were referred (Marsh, 1880) to this species.
Holotype
YPM 1452 includes a proximal right coracoid, proximal right scapula, and three fragments of a poorly preserved left humerus (fig. 11). As discussed in the Historical Background, some or all of the material incorporated into the YPM Ichthyornis victor panel mount frequently appears to have been mistaken for holotype of Ichthyornis victor. The YPM Catalogue entry for YPM 1452 included the phrase ‘‘Major portions of skeleton’’ for most of the 20th century.
Locality and horizon
Marsh (1880: 199) reported that YPM 1452 was ‘‘found in May 1876, by Mr. H. A. Brous, in Wallace County, Kansas.’’ No locality information was given in the original description of the species (Marsh , 1876), while the listing in Marsh (1880) was repeated in Brodkorb (1967). (Clarke , 2004)
