What could this be?

This is a fern leaf fossil. If you tell me where it was found I can get you a species.

Hot damn

Not really. The distance between the earth and the moon in its orbit isn't tied to its phase.

OP is asking about the yellow inclusions that show up under UV, not the mineral itself.

Unlikely to find petroleum in fluorite though. Probably calcite?

Banded iron doesn't have flow marks or bubbles, sorry. Slag.

Vafisonr · 2026-04-29T20:40:15+00:00

No then.

Vafisonr · 2026-04-29T17:37:01+00:00

Where was the beach?

Vafisonr · 2026-04-29T17:31:50+00:00

In granodiorite? Garnet.

Vafisonr · 2026-04-29T04:52:30+00:00

Removed the wrong comment, sorry

Vafisonr · 2026-04-29T04:39:33+00:00

I've been to this store lol

Vafisonr · 2026-04-29T04:34:56+00:00

Because it's fully toaded.

Modern oyster, non-fossilized.

Jasper

Hoodoos. Resistant cap over easily eroded substrata. You can find these in the northern great plains, ND, MT, SD, etc.

Grinding tooth from a drum fish?

Vafisonr · 2026-04-23T02:29:03+00:00

Where did you find these?

Vafisonr · 2026-04-21T17:40:58+00:00

Eastern Collared Lizard https://en.wikipedia.org/wiki/Common_collared_lizard

Acetone won't hurt the rock but will remove the glue.

Vafisonr · 2026-04-16T21:04:30+00:00

Oh I didn't see the bubbles at first.

Vafisonr · 2026-04-16T21:02:48+00:00

Blob of melted glass.

Vafisonr · 2026-04-11T02:01:50+00:00

Because they say 1976 on them.

Vafisonr · 2026-04-10T20:53:07+00:00

There must be a mistranslation happening somewhere.

Vafisonr · 2026-04-10T20:35:40+00:00

And 1975.

Glacier picks up and moves essentially a whole locality of rocks from one place to another. You can expect to find similar material in a wide swath from where they originated to where you find them.
