My German is non-existent. The article is in English. I am trying to get
the original references they cite which are
A. G. Sharove Tr. Akad. Nauk. SSSR Palaeont. Inst. 130, 104(1971
P. F. A. Maderson, Am. Natu. 106:424 (1972
H. Haubold et al, Acad. Sci. Paris 305(2)(1987) p. 645
Until then I can't answer your questions. This fossil was cited in a
discussion of bird origins recently which is where I first found it, and I
am trying to chase this down.
