Fossil-collecting is a hobby of mine. I live in a place that used to be an ocean bed several millennia ago. It is now a park with a lot of limestone shelves - which are perfect for finding fossils!

I wanted to share a few pieces from my collection, just because!

I hope the image quality is okay. I accidentally dropped my phone a few days back, and there’s been some slight problems with the camera since. ?

I found this fossil when I was eighteen. I was not as smart as I am now, and mistook it for a piece of spine. I flipped out, until I saw the limestone powder on the palms of my hands, and realized it was a fossil. Probably a piece of coral once upon a time.

Another side of the coral.

And another side to the coral.

This one is probably my coolest fossil. It’s obviously a chunk of ancient seabed, which blows my mind. Millions of years ago, these were living organisms resting in a sea bed. I am literally holding millions of years in my hands, and I’m always blown away by that.

A close up of the ancient sea bed.

Here’s the bottom of the chunk of ancient sea bed. Way back when, this was teeming with marine life.

This is something I found when fossil-hunting with someone else. We think it’s an iron deposit, because it’s sort of heavy. We found it lodged on the underside of the limestone shelf, but when he touched it, it fell into his hand.

EDIT: After posting to reddit/Imgur, this specimen was identified as a Pyrite module that’s been replaced by or coated in iron oxides. Nifty! :D

This was a curly shell! I have a soft spot for swirls, so I added it to my collection.

Another shot of the swirly shell.

This is another swirly shell, but it’s a little different. It’s ever so slightly bigger, and it has an extra feature on its underside, which I’ll show in a moment.

The swirl!

Underside of this particular specimen. There’s an extra itty bitty swirly shell! My initial thought was it was a momma swirly shell with a baby swirly shell beneath it, but that’s extremely unlikely in retrospect.

It probably was a shell that died before this one, and they’re just two fossilized corpses on top of one another. That sounds infinitely less romantic lol.

It was hard to get a picture of the little swirly shell, so I took an extra image below that circled it.

The iron one just might be a meteorite....

I just washed it - I typically don’t do that out of fear of damaging the fossil. It’s shiny, but not magnetic, so I’m not sure what it is.

Really? That’s so cool! Do you know where I could go to figure that out for sure?

The first one is an internal mold of a chamber from a coiled ammonite. Basically, sediment that filled in part of the shell.

Oh cool! Thanks! :)

The septa (walls between chambers) of ammonites were wavy and saddle-shaped to strengthen the shell, giving the mold that wavy shape.

The curved ones are referred to as devils toenails for obvious reasons. Can't remember the scientific name.

It does kind of have the demonic-toenail shape lol

Correct! They're oysters of the family Gryphaeidae. Common genera: Gryphaea, Exogyra.

That sounds familiar! Invertebrate paleaontology was a long time ago, for me and the fossils...
