    Nice tour JG! I hunted for fossils when I was a kid. Growing up in a coal mine town digging through tailings piles was one of my favorite pass times. You could find neat stuff there.

    Hello Marshall,

    I knew that this postcard will attract your attention, as you are another friend of fossils, minerals, and gemstones.

    Thank you all for the kind comments,

    JG
    That's pretty cool.
    I assume you are familiar with the Permian/Triassic extinction. I spent some time studying that event. I was particularly interested in the effects of increased sulfur and carbon dioxide from the eruptions of the Siberian Traps on the atmosphere and ocean processes. I looked for a correlation between the estimated carbon output at that time period with the present carbon output and the potential effect on our present environment. My main interest involved the effects of acidification of the oceans and atmospheric temperature rate changes that lead to the extinction event.

    Thank you Caddman for your comments!

    The burning hydrocarbons during the Permian, also due to the volcanic eruptions as documented in the Chemnitz area (Germany), are highly likely to have caused mass extinctions, especially of the plants.

    I have some unique Carboniferous/Permian fossil reptiles in my depository, must find them, and then I can post several pics. They belong to the oldest well preserved reptiles, anyway.
