Time: Lower Cretaceous (125 million years ago)
20 mm long 33 mm across Matrix: 90 mm by 60 mm
Site: Liaoning - Yixian Formation, Chaoyang, Liaoning Province of
Class Insecta is well represented in Liaoning and Hebei Provinces
of China, with over 500 species referable to over 100 families based
upon over 10,000 specimens. This fantastic diversity and exquisite
detail is unprecedented throughout the world. The most obvious example
is a large, detailed member of the Dictyoptera, or Cockroaches.
Notice the incredible detail in the venation of the wings. The many
freshwater clams as well as three Ephemeroptera larvae (to left)
present are indications of the aquatic environment in which these
types of specimens were preserved. There is one repaired matrix
crack which does little to detract from this one which appears to
have been caught in flight over the lake.
