Fossil representation: Sacrum, fragmentary pelvis and both femurs. When realised to be a pterosaur, other fragmentary remains found at the dig site and belonging to a then unidentified pterosaur were also attributed to the genus.
was once thought that Herbstosaurus represented one
of the first
of the more advanced Pterodactyloidea, however it is now
realised that it recovered from a Vaca Muerta Formation which dated as
being from the Tithonian. Herbstosaurus has
continued to cause some
disagreement between palaeontologists as to its exact position within
Herbstosaurus was described as a small theropod dinosaur until 1978 when the palaeontologist John Ostrom first put forward the idea that it was actually a pterosaur.
