Brittle star fossil or carving?

[DS20]

Hi all, I saw this cool looking piece in a rock store in a small US country town. There were many other fossils in the store but this one stood out to me with the contrast in the colors and reminded me of an alien creature. The store owner claimed it was real but I’m not entirely convinced. I loved the look of it so bought it anyway but thought I’d get your opinions on whether this was a real fossil in any way or just a pretty bit of art? It appears to be a part of the slab of rock and if it is carved they’ve done a very good job at getting all the details into this solid rock. Thanks!

Hi,

 

Artwork ! Everything is pretty much detailed, except in the disc which proves to be incredibly simple.

Ditto. I hope you didn't pay too much for it, ie. an appropriate amount for a bit of home decor.
