Cruralispennia multidonta was named by Wang et al. (2017) [A small enantiornithine with the following unique features: 14 dentary teeth; abbreviated, plough-shaped pygostyle with a pygostyle/tarsometatarsus length ratio of about 0.28; coracoid mediolaterally narrow with the sternal margin measuring only one-quarter of the proximo-distal length; sternum bearing a V-shaped caudal margin and two pairs of subequal caudal trabeculae; manus shorter than the humerus; postacetabular process of the ilium short and strongly ventrally directed; dorsal process of the ischium more distally placed; and pubis without a distal expansion.]. Its type specimen is IVPP 21711, a partial skeleton (a nearly fully articulated partial skeleton with associated feathers preserved on a single slab), and it is a 3D body fossil. Its type locality is Cruralispennia-type locality, which is in a Hauterivian terrestrial horizon in the Huajiying Formation of China.
