Xaveropterus becomes Sciuruminus

The fossil of 28-inches-long Sciurumimus was found in the limestone strata in Painten quarry (northern Bavaria) and preserves remains of a filamentous plumage, indicating that the whole body was covered with feathers.

The genus name of Sciurumimus albersdoerferi refers to the name of the tree squirrels, Sciurus, and means "squirrel-mimic"—referring to the especially long tail of the animal.

The species name honors the private collector who made the specimen available for scientific study.
