    Fossil Ephemeropsis trisetalis Insect Specimen from China 41x9 mm 11.2 gram

    A nice fossil specimen of Ephemeropsis trisetalis from China.

    Name:Chinese Insect (Ephemeropsis trisetalis)
    Location: Yixian Formation, Grey Shales, Upper Volcanic Series, Liaoning Province of China (NE region)

    Age: Lower Cretaceous (~125 m.y.a.)

    Size of fossil: 41x9 mm
    Size of mother rock: 92x62x1 mm
    Weight: 11.2 trisetalis
    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. This example is a fine Mayfly naiad (nymph, or larva) preserved in dorsal view. The tripartite abdominal extension from which the species derives its name, as well as the head, legs , and body segments are all exceptionally well preserved, making for a fine addition to any collection of fossil insects.
    Insect Order Ephemeroptera comprise the Mayflies. The earliest certain mayfly nymphs in the fossil record are from the late Carboniferous. The difficulty of placing fossil nymphs in an insect order, however, make this in dispute, with some authors claiming appearance as early as the Devonian is possible. Most fossil mayflies are larval fossils, ostensibly due to the very short time they have in the adult stage. After living as aquatic nymphs for one to two years, they live as adults only for a few days, an ephemeral existence indeed. When you only have a few days as an adult, finding a member of the opposite sex to perpetuate the species is of paramount importance; and any advantage would be a valuable trait. Both young and adult mayflies are an important part of the food chain, especially for stream fish.
    The wings of Mayflies have been hypothesized by some scientists to be highly adapted (tracheal) gills, leading to conjecture that their gill blades and insect wings have a common origin, and research continues into this question. Interestingly, extant mayfly nymphs do not have gills until after their first moult. This trait could be shared by the common ancestor of all flying insects.
