 Description:
The 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 exact age of the
Yixian Formation is still under debate, with some researchers favoring
the Early Cretaceous, some the Late Jurassic, and still others the
Jurassic/Cretaceous boundary. The family Caloblattinidae arose during
the Middle Triassic, and was an important component of many ecosystenms
well into the latest Early Cretaceous. Notice the excellent prervation
of the venation in the wings, making this an excellent example of
the taxon. There is also a small (7mm) member of the Corixidae, or
waterboatmen, seen as well. |
