This is a STUNNING AND EXTRAORDINARILY RARE quality of a Lower Cretaceous dragonfly fossil featuring a superbly preserved prehistoric dragonfly of the type Cordulagomphus sp. Not to be confused with a damselfly or lacewing, this is a true dragonfly of preservation that excels what many museums showcase in their collections. Unlike many insect fossils that are nothing more than a crude body impression with detail carved and painted on the rock artificially, you can clearly see very rare detail in the stone and protruding up from as well as into the stone. Wing vein detail is remarkable with original pigment throughout the wings and body. Left forward wing tip has been restored but otherwise, dragonfly is original. Rare head detail is visible including the eyes, the tops of some of the legs, and even the individual segments in the tail are preserved.
Not to be confused with a MUCH LESS VALUABLE damselfly or lacewing, this is a true dragonfly with preservation that excels what many museums showcase in their collections.
Many Brazil dragonfly fossils offered are NOT EVEN DRAGONFLY FOSSILS. We have seen many dealers selling damselfly and lacewing fossils as "dragonfly" fossils. There is a huge price difference in the two.
Of all the richest fossil-bearing deposits ever known, Brazil's Santana Formation is ranked among the world's greatest. Santana fossils are known for not only their extreme diversity but more importantly, for the nature of their breath-taking preservation - considered by scientists to include the finest examples of fossils in existence. The formation provides an amazing window into the paleobiota of a prehistoric world from the Lower Cretaceous, 110 million years ago. The Santana fossils of Brazil were first recorded in the year 1828 by two natural historians, Dr. J. B. von Spix and Dr. C. F. P. von Martius, commissioned by the king of Bavaria. To this day, they are still being studied with many new discoveries coming to light.
Rarely do fossils possess the preservation of those found in Brazil's Santana Formation located on the Araripe Plateau. The magnificent fossils include a vast selection of fish, insects and plants along with rare occurrences of the remains of pterosaurs, dinosaurs, frogs, turtles, crocodiles and miscellaneous marine invertebrates. Santana fossils are predominantly made up of two kinds of fossils which are classified as two different strata - the earlier Crato members which are found in shales and thin limestone layers and the later Romualdo members which are found in round limestone concretions. The lower or older Crato member strata occur as fossils in laminated limestones that were deposited on an undisturbed lakebed. These types include small fishes and a diverse fauna of insects and other animals suggesting a dry open terrestrial environment. A frog has been found in the Crato deposits along with the impression of a feather and pterosaur remains. Romualdo member fossils include a wide variety of fish, plants and rare occurrences of reptiles such as crocodiles, turtles, dinosaurs and pterosaurs. Most impressive are the fact that these concretionary fossils are preserved in a full three dimensional perspective and when prepared with the utmost care and skill, reveal features and anatomy that are akin to the animal being alive. The exact dating of these two members remains enigmatic although the Crato members are known to pre-date the Romualdo members. It is possible that both are within the same time zone of the Lower Cretaceous. Despite the long period of time these fossils have been known, much work remains in the study and determination of dating and the full breadth of the flora and fauna from the Santana Formation of Brazil.
