I work in the Your Lab at XYZ University. I learned about OpenWetWare from internet search, and I've joined because I am wanting to figure out why the insect fossils of Solnhofen Formation (Germany) only have the casts and molds of insect remains. Was the exoskeleton destroyed due to the saline in the water? Did chemicals bleach out the melanin so that the chitin is invisible? Did heat in the water play a part in the destruction of the exoskeleton?
Typically the schertization hardens the exoskeleton so it is not penetrable. I read somewhere that it takes a roach about a month to fall apart in fresh water, but I cannot find that article now. I know that hydrophobic acid prevents water penetration, but does that dissolve over time? Does low saline water speed the process of dissolution of proteins in the insect skeleton? These are some of the questions I seek answers to.
Thank you, Beatrice.
