The Missing Late Pleistocene Ostrich Femur from Zhoukoudian (China): New Information Provided by a Rediscovered Old Cast
A complete ostrich femur from the Late Pleistocene deposits of the Upper Cave at Zhoukoudian (China) was referred by Shaw to Struthio anderssoni in the 1930s, but its present whereabouts are unknown. A good quality plaster cast of the missing specimen has been found in the collections of the Natural History Museum (London). This cast provides interesting information about the morphology of this large ostrich femur, which had previously been only summarily described and not illustrated. Although smaller than the femora of the Early Pleistocene giant ostrich Pachystruthio, the robust femur from Zhoukoudian shows morphological similarities with them, and it is suggested that ‘Struthio’ anderssoni should be placed in the genus Pachystruthio. The importance of old palaeontological casts is emphasized, as well as the need to preserve and curate them properly.

A marine bird (sulidae, Aves) from the Langhian (middle Miocene) of Penedo beach (Setúbal Peninsula—SW Portugal) and its paleoenvironmental context - Journal of Iberian Geology
The fossil remains of birds from the Miocene of Portugal are scarce, encompassing a total of twelve specimens, from nine paleontological outcrops located in Leiria (central Portugal), southern sector of Setúbal Peninsula and along the lower Tagus Basin. This study focuses on a new specimen found in the Praia do Penedo Norte (Sesimbra) coastal cliff corresponding to a coracoid bone, attributed to Morus sp., a sulid bird, biostratigraphically framed by calcareous nannofossils within the middle Miocene (Langhian).
