I know it isn't, but it looks like a fossilized kiwi fruit.

Looks like some sort of a shell fossil.

Nice. It looks to be part of a horn coral.

Nice fossil; looks like that remote has seen better days 🙂👍

A horn coral fragment! Nice find.

Lol I know right it's a trooper 😅

Crinoid cross section most likely. That's really what it looks like, we have a TON of such fossils in the shale of the Sandia mountains overlooking my city. Up there you find them willy nilly in the rocks in many areas. I'd bet a crisp $10 bill that it's a crinoid. Extremely ancient as fossils go, I wanna say 3-4 billion years(?), don't quote that number lol

The ribbed and ridged external structure and interior radial pattern is very typical for rugose horn corals as shown below, but not typical for crinoids.

[PS: True crinoids don’t predate 485 million years ago, with possible ancestral forms from the Burgess Shale at no older than half a million years. Fossils with the kind of age you’re imagining are only known as primitive colonial micro-organisms, the oldest being cyanobactaeria at around 3.5 billion years.]

I'm no fossil expert, as I said don't quote me on this one. I'll defer to what you're saying here, you're probably right. It looks like some of the crinoids I've seen but in terms of morphology I've not researched the particulars.
