Featured Wee Burnished Black Cup, Signed; a Starfish?

I got this in Bishop, California, maybe 10 years ago. It was sold as 'Santa Clara', but I have little confidence in that.
The bottom is hemispherical, the sides are roughly 1 1/4" long, the opening is ~1" diameter, it's ~1 1/2" high, an' its weight is ~1 1/2 oz.
I cannot read the signature, an' hope one of you will be able to help me locate this with a place, an' the artist's name.
If it isn't a starfish, what might it represent? There appear to be marks, a bit hidden in the design, indicating 4 feet...an' starfish don't have such, nor do they have a mouth or eyes where this does.
The craft is high, with nary any indication of tool work; no visible seams, an' it's quite thin-walled. The sgraffito looks to be thru the burnished surface, as is the signature. The interior is quite smooth, but otherwise unfinished. As always, Thanks for lookin'!

 

I read Irma Juarez. Could be wrong. No, perhaps I'm not.

She appears to be (have been?) a Mata Ortiz potter (Mexico).

Very quirky. I like it !

 

Thank you, Debora an' Books!
I just realized the figure is probably a lizard, stylized.
I am happy to know of Irma Juarez, an' will further research her an' her works!
