Diagnosis
ReferenceDiagnosis
L. Hou and Z. Liu 1984A smaller Cretaceous shorebird. Claws are only slightly curved, with flexor tubercles. Phalanges are slender and have attachment channel for M. flexor tendons digitorum longus along each side. Digit IV is the longest. Tarsometatarsus is shorter than digits III and IV and laterally compressed, and is not fused completely in posterior view, and distal foramen large and prominent. Trochlea IV is shorter than trochlea III. Trochlea II is broad and in higher position. Calcaneal ridges and tendinal canals are not developed. Tibiotarsus is not supratendinal, highly compressed internal, and intercondylar fossa is deep. Internal condyle is slightly shorter than external condyle; internal condyle is extremely mediolaterally compressed.
