Langobardisaurus was just discussed less than a week ago with regard to Pteromimus. Langobardisaurus was a sister to other long-necked tritosaurs, like Tanytrachelos and Tanystropheus, and the shorter necked Cosesaurus.
Back in the day (the mid 1990s), when I was still tracing 8x10s with a pen on acetate (instead of a digital mouse after scanning) Dr. Silvio Renesto was kind enough to send a photo of his recently discovered Langobardisaurus pandolfi (Renesto 1994). Apparently it was missing a neck and skull (Fig. 1) but this taxon was of particular interest due to its elongated, pterosaur-like, tanystropheus-like pedal digit 5.
The Thrill of Discovery
As I continued tracing the specimen, I realized there were some extra parts present behind the dorsal ribs. These turned out to be the apparently “missing” neck and skull. Unfortunately much of the skull was hidden beneath the vertebrae, so the details were beyond recovery, but the general outline and anterior jaws were clear. The orbit was much larger than originally anticipated and the rostrum much smaller with more derived teeth.
That was One of my First Contributions to Paleontology
That discovery was later supported by the discovery of Langobardisaurus tonneloi (Muscio 1997), which clearly exposed a very similar skull and neck. I have been employing the DGS (digital graphic segregation) method ever since much to the chagrin of my colleagues. I have been ignored and vilified ever since in print and in private for announcing discoveries based on interpreting photograph evidence. Well, this promising start is how it all began. It’s been an uphill struggle ever since.
As always, I encourage readers to see specimens, make observations and come to your own conclusions. Test. Test. And test again.
