Time Period: Lower Cretaceous ~ 108 - 92 MYO
The Santana Formation is a geologic Lagerstätte (undisturbed fossil accumulation) in northeastern Brazil's Araripe Basin where the states of Pernambuco, Piauí and Ceará come together. The slightly older insect-bearing area of the strata has been named the Crato Formation by David Martill. While quarrying for paving stones, insect fauna was exposed. In addition to the great variety of insects, spiders and scorpions, many plants have also been discovered. This specimen is a member of the Odonata (dragonflies and damselflies). The Odonata are well-represented in the fossil record, with some 700 species known.
