Some of the fossils belonged to a giant pterosaur known as Arambourgiania philadelphiae and provided a first look at its bone structure, as well as confirmation that it had a wingspan of 32.8 feet ...

Normally, pterosaur bones, being hollow, are extremely fragile and prone to being flattened like pancakes during fossilization. However, these fossils retained their three-dimensional structure.

“There is such limited information on the internal bone structure of pterosaurs across time, it is difficult to say with certainty which flight style came first,” said Rosenbach ...

Newly collected specimens of the already-known giant pterosaur, Arambourgiania philadelphiae, confirm its 10-meter wingspan and provide the first details of its bone structure. CT images revealed ...

showed an entirely different structure inside the hollow bone. The scans exposed internal supports resembling the struts of an airplane’s wing, which are also found in the bones of contemporary ...

The other fossil analysed was part of a pterosaur with a five-metre wingspan. The CT scans revealed the structure of its flight bones was completely different from that of the bigger reptile.
