Permian fossil help

I’m sorting through some micro-matrix that is said to be from the “Ryan Formation” however I’m pretty sure that’s just the Wellington formation. I’m looking for some sort of ID on this, It’s about a half centimeter long. My apologies for the poor photo quality, It’s just so tiny and my equipment isn’t good enough

I am not all familiar with bone anatomy. I have heard and seen pictures of amphibian bone fossils from that formation. That's the first thing crossed my mind when I saw your pictures. I would wait on others to say something.

Looks like a toe bone.  Couldn't tell you what it is from though, sorry.

Looks vaguely like a metacarpal. Couldn't tell you if this is from an amniote or amphibian; metacarpals are notoriously devoid of useful diagnostic features.

Yes I’m sure it’s some sort of amphibian, possibly even some sort of amniote
