The Ctenochasma – Pterodaustro transitional taxon

This post has been modified with a new reconstruction, heading and text.
A pre-Solnhofen ctenochasmatid pterosaur has been announced here and here. Please take a look at those links to see the fossil itself. Both sites can be clicked for enlargements.

Figure 1. The new Propterodaustro pterosaur reconstructed. While it nests between Ctenochasma and Pterodaustro, certain traits are distinct from both.

The new pterosaur nests here between Ctenochasma and Pterodaustro.

“The discovery is of similar interest like Archaeopteryx,” says the director of the Bamberg Natural History Museum, Matthias Mäuser. Over 400 teeth were reported. The long teeth are not pointed, but with “small  thickened lobes (Google translated from the original German)” explains Mäuser. He reports, “the food was not chewed or retained, but filtered out of the water – as do baleen whales and flamingos with the slats in the beak.”

“The 155 million year old animal is different in physique from other known species – and its remnants are extremely well preserved. Scientists speak of a major discovery. The specimen had very long arms and long legs, almost like stilts. Fish remains are found in the belly.”

“The Bamberg piece shows that these giant pterosaurs had their origin in the Jurassic period,” reports Dr. Eberhard (Dino) Frey. Such a nesting, at the base of the azhdarchidae, is not confirmed in the present study.

As always, I encourage readers to see specimens, make observations and come to your own conclusions. Test. Test. And test again.

Evidence and support in the form of nexus, pdf and jpeg files will be sent to all who request additional data.
