Diagnosis
ReferenceDiagnosis
J. O'Connor and G. Dyke 2010Sinornis santensis (BNHM BPV 538) differs from C.
yandica (IVPP V9769) in that: (1) the first phalanx of the minor digit is curved (cf. straight in C. yandica) and proportionately longer relative to the first phalanx of the major digit; (2) the claw of the major digit is proportionately larger relative to that of the alular digit; (3) the postacetabular wing of the ilium is proximally broad, curved and tapered distally (cf. ‘strap-like’ in C. yandica); (4) the ulnare is U-shaped with a relatively deep narrow incisure (wide and shallow incisure in C. yandica) and; (5) the pygostyle is shorter (3⁄4 the length of that of C. yandica).
