Far out. Possible conclusions:
1. If made in 1890, it's real.
2. If made after, a gifted "artist" created it.
My guess? Fake, else the owner would be tripping over themselves to get it to a scientist or lab for their own curiosity, which has not happened. Nor would an organic being have been preserved in such a pristine state in an above ground, unprotected, evaporating solution of anything for 100 years.
Fake fake fake. Move along before it comes to life and reproduces since dragons are supposed to live forever according to the song.
BWA HAHAHA!!
