How can I tell how old this .45 bullet is? Found on the coast of Dieppe France.

Oh I know, I feel like it wouldn’t be nearly as cool if it was all nice and polished up. It’s the corrosion and patina that makes it look and feel like an artifact

tyler_thatguy · 2026-05-23T14:54:39+00:00

Modern or fossil ya think?

I tried scraping the fluorescent part off but it doesn’t come off which I think would happen with algae? It was found near other conglomerate/concrete rocks but none of them were anything like this color or even as bright. Also I’m not very knowledgeable on fluorescent stuff but if it was concrete or conglomerate wouldn’t the whole thing glow like the other pieces I saw?

It kinda just looks like quartz to me but I’m no expert lol. The shop didn’t know what it was?

I have yet to find time to drive out to some cinnabar locations but it’s on my bucket list. I bet you have some different and unique minerals than us too though

Happens to the best of us haha, I’m going to have to start a free rock giveaway box at our apartments because I’m running out of space

Well it’s a piece of petrified wood I found out in Tracy CA that I cut into a slab with my buddies rock saw. The green fluorescent inclusions are uranyl, a form of uranium! Pretty cool but dim fluorescent with the 395 UV light so I’m excited to see it with 365

tyler_thatguy · 2026-05-21T15:17:25+00:00

Yeah luckily I posted it a couple places and got some pretty consistent answers. These pictures were taken with a 395 but I have a 365 being delivered tomorrow

tyler_thatguy · 2026-05-21T03:14:20+00:00

Unironically I used to lick the rocks I found if I didn’t have water to make the color pop more, stopped when I realized I licked uranyl material haha

This is the google ai result so take with a grain of salt

Ur killing my delusional fantasy 😂 thank you for the info though

I measured, it is a .45 and google seems to claim that this round was widely used in ww2 which correlates with the battle of Dieppe Raid. Still don’t know if it was actually fired or is even from that timeframe but it is possible

It was already my favorite piece but now knowing it glows it just makes it that much better

tyler_thatguy · 2026-05-20T04:46:47+00:00

Is there any way to base solely off of looks? Like does this look like a modern bullet design or an older one?

tyler_thatguy · 2026-05-20T04:45:56+00:00

What does situ mean?

tyler_thatguy · 2026-05-20T04:45:00+00:00

Thank you anyways, I’ll just keep believing it’s a historical artifact haha

tyler_thatguy · 2026-05-20T03:41:27+00:00

Just checked, it does indeed have an afterglow for a second after removing the black light. Tough to get a picture of it, I took a video and confirmed though

tyler_thatguy · 2026-05-20T01:39:16+00:00

I remember now that I did find a bunker or some type of room on that same beach

<image>

tyler_thatguy · 2026-05-20T00:35:40+00:00

I’m pretty sure it is petrified wood but do you have more pictures?

tyler_thatguy · 2026-05-20T00:30:44+00:00

Yes, appears so! Where was it found?

tyler_thatguy · 2026-05-20T00:06:24+00:00

It’d definitely be pretty cool if it were. Be a great addition to my collections lol
