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 
Lesmahagow too.
