Xu's interpretation was supported by further study of the "Juravenator" fossil. The first follow-up study to the initial description reported that faint impressions of filamentous structures, possibly primitive feathers, were present along the top of the tail and hips. A more in-depth study, published in 2010, included an examination of the specimen under ultra-violet light by Helmut Tischlinger. The examination under UV revealed a more extensive covering of filament-like structures, similar in anatomy to the primitive feathers of other compsognathids, including "Sinosauropteryx". The investigation also discovered additional patches of soft tissue, on the snout and the lower leg, and vertical collagen fibres between the chevrons of the tail vertebrae.
