The Jehol Biota Group ranges from the Late Jurassic to the Lower Cretaceous and is famous for its remarkably well-preserved and widely varied prehistoric fauna including the best known components of the Jehol biota - the feathered dinosaurs and primitive birds.  They have been intensively studied and have attracted a great deal of public attention.  The discovery of small dinosaurs with feathers with feathers has strengthened the dinosaur-bird evolutionary link. 

This is a choice quality intact fossil stone plate showing a mass death assemblage of mayfly larvae of the  Ephemeropsis sp..  The plate is unbroken with both sides showing 100% natural and authentic, NATURALLY pigmented fossils of these larvae.   NO REPAIR OR RESTORATION.

The Jehol Biota is particularly noteworthy for the very high diversity of fossils and the very large numbers of individuals of each species that have been recovered.  Discoveries include fossils of plant macro- and microfossils, including the earliest angiosperms, charophytes and dinocysts, snails (gastropods), clams (bivalves), superabundant aquatic arthropods called conchostracans, ostracods, shrimps, insects, spiders, fish, frogs and salamanders (amphibians), turtles, choristoderes, lizards (squamates), pterosaurs, and dinosaurs including feathered dinosaurs, the largest mammals known from the Mesozoic, and a great diversity of birds including the earliest advanced birds, and the smallest and largest birds known from the Mesozoic.  The preservation of the fossils in this deposit is stunning with soft-body tissue details and anatomy seldom seen in other fossil deposits of the world.
