Hollanda luceria
''Hollanda'' is a genus of small ground birds known from fossils found in the Barun Goyot Formation of Mongolia. Found at Khermeen Tsav, it dates from the late Cretaceous period (Campanian stage), about 75 million years ago. Known only from partial hind limbs, ''Hollanda'' has long legs with an unusual configuration of the toes. These indicate that it was a fast-running ground bird, possibly similar to the modern Roadrunner.〔Bell, A.K., Chiappe, L.M., Erickson, G.M., Suzuki, S., Watabe, M., Barsbold, R. and Tsogtbaatar, K. (2010). "Description and ecologic analysis of ''Hollanda luceria'', a Late Cretaceous bird from the Gobi Desert (Mongolia)." ''Cretaceous Research'', 31(1): 16-26. 〕 Its relationships are uncertain. Some studies have found that it was an relatively advanced bird, a member of the Ornithurae, related to birds like ''Ichthyornis''. Other studies have recovered it as a member of the primitive family Songlingornithidae.
