I found it hiking near Lethbridge, Alberta years ago, just found it again while going through old boxes. The wavy lines look kind of organic, but I don't know about the rest.

Mountain oyster has a different meaning haha

It doesn’t look like any fossil I’ve seen before. But it’s certainly strange! I would take it to a university and see what they know.

If that crack goes all the way around. Give it a good wack with a hammer on the seam and it should pop open for you to show you whatever is hidden in the middle. (If there is a fossil in there). Often times it's just empty but you never know. If it looks like it contains something take it to a specialist instead of trying to clean it up yourself.

I don't want to hurt the squiggles :(

[–] phonics@lemmy.world 4 points 2 months ago (1 children)

You won't. Just tap it to loosen it. Don't smash it to obliterate it. Also put on some protective eyewear and maybe gloves. Don't want ancient shards in your body

Fine! Maybe. My curiosity is greater than my attachment.

[–] phonics@lemmy.world 2 points 2 months ago (1 children)

Yeah boi! Can you reply to me with a pic of what's inside so I don't miss it?

[–] Wren@lemmy.today 1 points 2 months ago (1 children)

I will! But it might be a while. I found it in a box when visiting my parents. Put it back in the box before I left.

That was delightful, thank you.

It looks like 2 pre-made frozen beef patties separated by a sheet of paper, but it's super incredibly freezer burnt.

The waves look very regular to me, maybe something like this? https://au.grandado.com/products/plastic-garden-edging-fence-border-green-corrugated-landscape-tidy-lawn-divider-prevent-overgrowth-of-grass-newest?variant=UHJvZHVjdFZhcmlhbnQ6ND

Not sure how multiple layers would break in a cross section. Maybe sediment plus freezing could make it brittle?

[–] jamesrandysghost@lemmy.zip 1 points 1 month ago (1 children)

That layer that runs through the middle, does it flake apart easily or is it pretty solid?

I've got a couple pieces that remind me of this, I'll dig them out and see if my memory serves me right.

[–] Wren@lemmy.today 2 points 1 month ago

Do share them! It's pretty solid. I can't conduct further investigation until I'm visiting my folks again.
