This plaque of amber displays a most uncommon inclusion: a complete
scorpion juvenile. The oldest amber containing insects comes
from the deposits of Lebanon at some 135 million years of age.
Deposits in Myanmar, New Jersey, and Japan are somewhat younger.
Despite the fact that scorpions have an extensive history dating
back to the Lower Devonian, Mesozoic examples are quite rare,
with most known examples from the Lower Cretaceous of Brazil
and a single amber specimen from Lebanon. As of the publication
of the cited work by the AMNH the only examples from Burmite
amber were three fragments, one which was of the sting. That
publication was prophetic in that it predicted there was the
likely possibility that a complete example would eventually come
to light. In the years since a few have indeed been found, with
this example notable in that it is easily seen in this clear
piece of amber from the time of the dinosaurs.
