[1] The holotype specimen of Miodytes is a slab that contains the right wing skeleton of the bird, nearly completed, consisting of the distal fragment of humerus, ulna, radius, carpometacarpus and parts of the wingtips (RGF 97/3).

Due to the nature of the bones in the slab, the authors Dimitreijevich et al. (2002) used the humerus part and the carpometacarpus to provide comparative anatomy and a diagnosis.

Miodytes can be differentiated from other grebes as the genus has a well developed epicondylus ventralis and a very deep and long sulcus musculi brachialis.

Ksepka et al. (2013) argued at best Miodytes is a member of Mirandornithes, as it does have a strongly elongate phalanx II-1 which lacks an internal indicus process.

Inferring from the ecology of modern grebes and how the specimen was preserved, Dimitreijevich et al. (2002) suggested Miodytes was a migratory species and the individual died from an accident, not predation.
