It was a small pterosaur, even as an adult.1

Its neck bones were long and had weak ridges on top.1

The deltopectoral crest (a part of the upper arm bone) was 30% of the length of the humerus.1

Montanazhdarcho had no teeth in its lower jaw.1

It lived during the Campanian stage of the Late Cretaceous, about 83.6 to 72.2 million years ago.3
