Early Cretaceous - Araripe Basin, Brazil
An outstanding fossil grasshopper, of the order Orthoptera, from the Crato Formation, Brazil, 108m to 92m years old.
The Araripe Basin, in Brazil, is home to an amazing variety of wonderfully detailed Early Cretaceous fossils.
The entire formation is known as the Santana Formation, but there are distinctions, and the slightly older, lower, insect-bearing strata, is now known as the Nova Olinda Member, of the Crato Formation, Ceara.
As usual, it is quarrying operations that expose the remarkable insect fauna, just as quarrying for lithographic limestone in Solnhofen has produced an amazing variety of superbly preserved Jurassic fossils in Germany.
As well as many orders of insects, spiders, scorpions, decapod crustaceans, and many plant fossils have been found.
To date no vertebrates have been found in this layer, in stark contrast to the overlying Santana Formation deposits.
When you consider the age of these fossils, they have changed little over millions of years.
You have only to look at the preservation on this insect to know what a wonderful piece it is.
The antenna are just perfect.
Size: 8.5cms (3.4") x 9.5cms (3.8")
