Anhanguera blittersdorffi

Anhanguera (meaning “old devil”) is closely related to Ornithocheirus and shares some similar attributes, it is also in the family Ornithocheiridae. The skull of Anhanguera is very similar to Ornithocheirus it has the same shape and general structure, its mouth is also crammed full with long sharp teeth. Remains from Anhanguera have been found in Brazil at the famous Santana formation. It was named after the town of Anhanguera in Brazil, where it was discovered.

The fossilised remains of Anhanguera were revolutionary in helping to end some debates on whether pterosaurs could walk on two legs or four. Anhanguera could walk on either two or four legs meaning it quadrupedal. Fossil remains of Anhanguera have been found in the U.K at the famous chalk of England‘s Cambridge Greensand, of the lower Cretaceous Cenomanian stage. Anhanguera also has been included, is to show the similar characteristics of pterosaurs that lived far away from one another in geological and geographical terms but shared an evolutionary similarity.
