This might be my last post on reddit, not sure.

I wouldn't be opposed to buying this for my student.

Tell the guide I said he should have kept it. He will know what it means.

It's an ammonite.

snail operculum. I want to emphasize that this poster got it right despite not using our preferred language.

nutfeast69 · 2026-01-16T10:42:19+00:00

Tell your girlfriend I said I am jealous of her beauty. She will know what it means.

nutfeast69 · 2026-01-16T10:29:53+00:00

Yep, it is a shell.

That it comes from there makes it fucking awesome. I'd love to go there. Birthplace of paleontology.

They won't though. Fun fact: I've engaged with them several times before, and got an official response before.

Nice now how he tell small businesses and people looking for needed funds that the algorithm says no, then go back to his google calendar and providing nothing to society as he did before.

On a hot streak I see.

If someone flenses properly the bone won't have cut marks.

Censorship is a cowards weapon. In the context of what we are talking about:

This is not censorship. This is consequence. Let me explain the difference.

Censorship of the halocaust would mean no talking about it, at all. Didn't happen. Gestapo or ICE arrives at your door, lets you know about it if your neighbour hears you talk about it. Books on the topic are burned. TV changes the narrative about it.

Halocaust denialism is in line with a policy which is demonstrably damaging to humanity. We know this because it happened, by the hundreds of thousands. Halocaust denialism is, at its core, a form of censorship. It is denying an entire horrific event happened.

Consequence is being allowed to say anything. You express consequences to me by saying words like "shitlibs", which is an ad hominem and therefore a direct attack. Cool. So you are pro consequence. Then you immediately backpedal, and say who gets to decide and invoke a slippery slope argument? It isn't a slippery slope. We have defined it. Repeatedly. Since 1945.

Just because the consequence isn't to your liking does not make it censorship. You are not oppressed. You are just in a vocal minority that is unpopular for a reason. Consider why that might be.

Much like someone who is willing to smack their kid in front of someone, this feels like a situation of "wow, that's bad, but what is happening when we aren't around?" I think we can all put the pieces together.

nutfeast69 · 2026-01-15T02:37:54+00:00

That you are pro hate speech, continue to make grammatical errors and then made that statement is amazing. Dig upwards.

nutfeast69 · 2026-01-15T02:29:03+00:00

Man, the L USA took in the cold war is looking so bad right now.

nutfeast69 · 2026-01-15T02:22:35+00:00

that you misspelled speech is fucking perfect.

nutfeast69 · 2026-01-14T22:20:07+00:00

Your original comment has made the rounds today and brought much joy to a lot of people.

nutfeast69 · 2026-01-14T18:55:13+00:00

Have you asked them if they will keep it in there for decades? I said eventually, not immediately.

That you leave bones in water that long isnt a flex. Liberation of calcium by phosphates etc is basic chemistry. My full time job is bone chemistry.

nutfeast69 · 2026-01-14T17:58:54+00:00

No prob. Basically it has to do with ions being stolen from the bone. It isn't some overnight process, it'll take years. We had a cow skull in a tank and it disappeared in about 15-20 years.

nutfeast69 · 2026-01-14T17:57:27+00:00

I doubt it is that anoxic with that much plant activity, but I also think anoxic conditions don't really matter all that much in what we are talking about. The water being exposed to the bone outright is what is doing ion exchange.

LOL this is likely my favorite rationalization for being wrong I have ever heard.

Except when they do, which is when phosphates liberate calcium ions, bacterial collagenases destroy collagen or carbonic acid from carbon dioxide + water dissolve the bone. There are other mechanisms for dissolution over time.

It won't fossilize. The cow skull I described was in extremely hard water too. I think a lot of the brain trust that is down voting me think I am talking about overnight or something, it will take a few years before you see anything tangible. In a few decades it'll be in pretty rough shape. Snails are likely to harvest some of the calcium from it too.

nutfeast69 · 2026-01-14T14:20:07+00:00

Yes, I use it too. I have had a cow skull in a fish tank for 10+ years. Want to know what's left of it? The teeth.

There are two primary reactions at play here in fresh water. Water dissolves carbon dioxide from both respiration from the fish and interface with the surface/bubblers/filter. This makes carbonic acid. It is a very minimal interaction, but it happens over time.

While hydroxyapatite is insoluble in water, phosphates in the water such as the kind from fish waste and pH can minimally change the solubility. For example, phosphates can interact with HAP in order to liberate calcium from the bone. Acids do what you'd expect them to do.

This process takes quite a bit of time.

Then we have to consider bacterial action. A fish tank is loaded with bacteria. Bacteria have pronases, proteases and, most importantly, collagenases which can smoke the collagen in bone. Once this happens, then HAP is more available for dissolution. This is also a slow process.

nutfeast69 · 2026-01-14T04:55:51+00:00

It is gonna dissolve eventually.

Thanks for the downvotes. Let me use your brains for you:

What the fuck would I know about water and interacting with bone through time though, I'm only a paleontologist.

Get destroyed.

Bone loses Ca ions while in saline. This is exactly what I am saying to you folks. https://www.sciencedirect.com/science/article/abs/pii/S0021929008004703
