Liaoning Cretaceous Blattaria Insect FossilLiaoning Province in northeast China has remained one of the hottest paleontology study sites on earth the past two decades. Liaoning is perhaps most famous for discoveries of feathered dinosaurs. From feathered dinosaurs to birds to reptiles with color patterns, the fine lake silts of Liaoning preserved the most intricate of life from more than 100 million years ago. Relatively hard to preserve insects are well represented in the diverse BlattariaLiaoning biota. This cockroach fossil from the age of dinosaurs exhibits many fine details such as the venation in the wings. Note also the many fress water clam fossils.

The earliest cockroach-like fossils are from the Carboniferous period some 354–295 million years ago. They differed from modern cockroaches by having a long ovipositors. These early roaches are believed to be the ancestors of not only recent forms, but also the mantises. The earliest fossils of modern cockroaches having internal ovipositors date to the early Cretaceous.
