Most extinct dragons, especially smaller genera are only known by one specimen. Mirolong is no exception, but in this case it's at least a very good preserved one. To be honest the preservation state is astonishing. The fossil was found in the Shanwang National Geological Park which is known for fantastic fossils of all sorts and more than 600 species of plants, invertebrates and vertebrates.
Beside big parts of the skeleton there are also soft tissue parts. A small part of the wing membrane is known and a scarp of skin, but the most exiting feature are the two very long scales and a couple of similar bristles at the hips.
Mirolong was- how phylogenetic analysis recently confirmed- a sister taxon of the Cryodraconidae and near related to Eoiactator.
This species may change the way we depict early Cryodraconidae and the evolution of dracofuzz.
