I thought the rest of the list may want to know about this, hence
this reply. Arachnids are represented in the Rhynie Chert near
Aberdeen in Scotland. Terrestrial arachnids (which are not insects)
are found in the Dryden Flags and Shales that are thought to be
Pragian in age based on spores (390-396 Mya). If you include
scorpions in this discussion, then you have to take it back into the
Silurian. I know of one scorpion that was found at Lesmahagow (birth
place of the person who wrote the Canadian national anthem) from the
Llandovery age rocks there. Both these localities are well
represented in our collections and we have the scorpion from
