I don’t really know, but they all came sealed in airtight bags that we had to cut open. They had some preservation chemical sealed inside as well, not formaldehyde at the time because it was known to cause cancer. But the smell was something I’ll never forget.

There was enough for all of us to pair up and share one, so it was a lot of pig fetuses. They looked like they were very late in the gestational phase about to be born, because they had all their bits, hooves, eyes… basically fully formed newborns right before birth.

I can only imagine someone had a connection with a slaughter house because of the sheep’s heads as well. Probably things the farm would toss out but made a buck off of selling for dissection to local labs.
