Silverfish, Pseudoscorpion & Huntsman
I am not sure what to highlight on this. All three are rare. the silverfish (order Thysanura) and pseudoscorpion (order Chelonethida) as very rare animals to find in amber. With the silverfish, you can see the entire body and the very long, two cerci and central longer, terminal filament at the tips of its abdomen. You just do not see them like this very often. The order Thysanura, in particular, may be the direct ancestor of winged insects.
This is a large chunk of amber, almost 3 x 1.5 x .5 inches in size (scanned image shows it well.)
The piece is about 1.5 x 1 x .25 inches.
