A friend of Tammy's has a chunk of amethyst crystals and was curious as to what the rusty orange highlights on the crystals might be caused by. I'm assuming it's some sort of iron oxide deposit leftover from when the amethyst crystals were created within the geode. I know that impurities of iron are responsible for turning the colorless quartz into a lovely purple amethyst. Has anybody else seen these rusty highlights in their amethyst specimens? Cheers. -Ken '

Hello, Found this on a beach in Algarve, Portugal. It looked like a piece of rust, and it was a little magnetic. With pliers, I broke the rust, and inside there was a metallic, hook-shaped object. What can it be? How old could it be? Thanks

Heres another. This is some sort of impression? Dunno. Does not look like much can be made from inspecting it but thought someone might find it interesting...or not.

Hey All, A couple Dinosaurs from this week. @Bobby Rico motivated me to get back into watercolors/ painting again and unfortunately the results are not what I would like. The watercolor Aucasaurus sports multiple mistakes and errors, one being the lack of realism in the overall painting. The predators mottled coloring also caused problems as I strove for a dappled sort of camouflage. Its obviously time to get back to painting. The other dinosaur, Torvorsaurus, was drawn in pencil as a perspective exercise. While the piece lacks detail, the movement in the Torvosaurus creates a sense of excitement that adds to the overall drawing. The jaw in mid-roar was extremely difficult but it seems to have turned out well. I liked it better then the watercolor because of the watercolor's overall shoddiness. Thanks for looking Watercolor Perspective sketch

This rock was found in Michigan. I has an odd shape. but also has two different "layers".. In the second picture you can see the "layer" , and something embedded into the rock like a stem? The rock Doesn't look sandy, but with a hand held magnifier you can see sand.Any ideas? Thank you.

I have a question about rust covered fossils (or not fossils!) is there an easy way to determine if the rust covered object is possibly a fossil (other than just being able to see it is a nail, etc)... how can I safely remove the rust if I am not sure what is under it? I ask because I had one piece that I was SURE was some metal object, but then when I cleaned it up, it was a little petrified twig... I have about 20 of these rusty objects and I've tried cleaning some, but I am afraid of damaging something since I am not sure of the material, and the rust had made the objects take on different shapes... what's going on here? Can anyone explain this to me? Thanks!
