Dog Skull Maceration OR Another Disturbing Project by Bio [WARNING: GRAPHIC PICS!!!]

Two things strick me about this thread. First, a college not keeping a dermestid colony anymore due to cost. As an entomologist I'm pretty familiar with that whole system and since it was already set up the cost would have basically been nothing. Dermestids don't take water and they will live months without food. Throw in a little leftover food once in awhile and they would be happy. I think someone just didn't want to mess with it anymore.

Secondly, the difference between a rural area and cities. I've had horse, cow with horns and so on skulls and I couldn't even give them away.

I don't remember saying we stopped the beetles due to cost, but my memory lapses are well established among those who know me. I scanned back and didn't see it, but I may have said it somewhere.
Cost was not the issue. The school was putting no money towards the venture, I donated my time, and actually spent some of my own money to bring in specimens. When we first set up the tank, we had it in the "new" wing of the science building. However, one of the professors using the lab complained. They claimed there was an odor, no one else I talked to could smell a thing. Honestly, based on hints dropped, I gather there was some sort of territorial infighting going on, and I could have had the cure for cancer in there and still been evicted. Luckily, the physics dept agreed to let us use a corner area they were not using, and the beetles were moved to the "old" wing of the building. The physics students never even knew it was there, lol. This went well for a while. However, then the "old" wing was to be shut down for renovations, and the project was homeless again. We tried keeping the beetles in an enclosure outdoors made from an old refrigerator, but too much moisture got into the tank, and the beetles got mites. I asked around on a taxidermy website for mite cures, and was told there wasn't much to do except nuke the tank. With no stable or semi-permanent home for the colony, restarting it seemed like a lost cause. I am hoping, that with the "old" wing reopening this semester, we will be able to get the beetles going again. The trick will be finding an unused hood in which to keep the tank. We still have a freezer brimming with specimens, so the professor I am working with and I really want to get the beetles going again.
But the issue was never really cost. You don't have to feed these guys much to keep the colony going at low numbers.
And I believe you about the difference in skull value from area to area, lol. You just don't typically find a horse skull laying around while walking through an urban area. I keep hoping to pick one up someday!
 
You know, I don't know how it works /laws, but many animal shelters kill then cremate the animals, they might let you make use of a body, not sure. Maybe in a rural area.

The biggest thing I've done it with is a cat, and I let nature take it's course - sitting out in the middle of summer, ants and maggots make quick works of the flesh.. then I just worked on it - surprisingly I have a weak stomach, but I can do that... Darn you! You're making me want to start doing that again.
 
I would just use a scalpel and dissection scissors.Don't go ANYWHERE near bone though. I have ruined specimens trying to get dried flesh off, and cutting off delicate bone. After you get all the real easy stuff, soak it for 24 hours. Remaining flesh will poof up with water (and you will probably see flesh you didn't know was there). Use a scalpel and try to gently scrape the meat off. I have heard of people even buying some kind of powdered meat tenderizer to help with this, but I have never tried this, nor do I know where one finds powdered meat tenderizer. Otherwise, just keep soaking and scraping. Be careful with the fish skull though...it might be more liable to disarticulate than a mammal skull. Just keep an eye on it.

Thanks! If I can find one, I'm going to try to get an obsidian blade. I'm used to working around delicate materials, so this shouldn't be too terribly different. I've had to peel the skin off of one of the catfish skulls, which was a nightmare. As soon as the studio opens I'll be soaking these things.

The largest catfish skull is already in 3 pieces (lower jaw separated when I found it). There are still some insects eating away at it, so I'm going to let them finish before it gets soaked.
 
Could you put a top that is black on your vat 'o bacteria? (paint it or put black plastic with holes?)

That might help keep the temp up if the summer starts to wind down before the head is done.
 
I always wanted to do this, but never could get the beetles...
 
I found a dried out snake once that I picked apart, but too much of it was damaged skeletal wise so I didn't keep it.
 
Any more pics? This is fantasic.

Growing up, we would often take skulls and place then under chicken wire secured to the ground so that scavengers wouldn't carry them off. They were left out in the sun for a few months to get cleaned by maggots, bugs, ants and bacteria. Luckily we had the space on the farm to have it about 500m from anything resembling a building.

Would love to see your collection Bio.
 
I heartily agree! You are extremely cool!!!

Awwwwwww! :hearts:
I think I am extremely....something, lol.
But I think YOU are extremely cool! And my shellies swimming around their holey rock castles agree!!!

Actually, I do have some more pics to post. Finally finished Fido! I am pretty pleased with how it looks, and it has joined the others on my display shelf in my room.
I can try to get a few photos of my other skulls as well, although they are in some disarray. I am not super organized, and I had to tear apart the case a bit recently, after I got a few wild dermestids who decided to hit up my stuff.
I can try to get some stuff up tonight, after classes.

That's frustrating, isn't it? It seems like a dried out critter would be easier, since a lot of the mass of the animal is gone. But it is much harder to clean them, or almost impossible if they are small. You really have to rehydrate it, to distinguish flesh from bone. One of my professors had be try to skeletonize a dried hummingbird once, and I wasn't able to do it. The whole thing just fell apart.
