Hello, I acquired these pieces of "Burmese amber" of Myanmar on an auction site: shipping from China. They have irregular, natural-looking inclusions such as tiny Diptera flies, wasps etc., and feel very lightweight and relatively warm to the touch. However, that fact that they ship from China made me nervous so I did some tests, and I think I'm down to Amber vs. Polystyrene for the following reasons: 1. I did the saltwater test. These pieces float in saturated saltwater, which to my understanding narrows it down to amber, copal and polystyrene. 2. I

Hi guys, I'm new here! I just wanted to ask if the burn test is always reliable. A year ago I found a tooth near a creek, it's certainly bovid but I still can't understand if it's a modern one or prehistoric/Pleistocene. I've burnt it and it doesn't smell like burnt hair, but at the same time it kinda smells weird. So does the burn test always says the truth?

I made this chart about the Greenriver formation, and I was making sure I had everything right. I know I am missing 3 fish, but I could find no evidence of predation or them preying on any other fish. My conclusion was that Amia was the super predator!

Using mohs hardness scale test for selecting blasting media?
Scuter posted a topic in Questions & Answers
I had received a rock hardness tester kit and was not shore what to do with it. Through some research I was able to find that the testing was known as a mohs test, and this test classifies rock in a 1 to 10 scale. This is nominally used for minerals, but what I was cureus about is using this scale for matrix uncovering fossil prep. If this is possible I wish to use this identification poses for selecting a blasting media. Duos anyone know if this is possible? -
So I could not help myself and just had to sate my curiosity and got one of the "real" looking eggs from our favourite auction site. I took some close up photos. It's pretty heavy. Not resin, can't burn or melt it and doesn't release any smells. Any other tests I can do or visual cues? It has a lot of grey-whitish on remaining eggshell and thinking it could be a morter they rubbed on. Ideas? Advice on tests?
