Paleontologists have made a stunning discovery whereas looking by means of 100-year-old fossil collections from the UK – a brand new thriller species of pterosaur, not like something seen earlier than.

Lead creator of the venture, University of Portsmouth PhD pupil Roy Smith, found the thriller creature amongst fossil collections housed within the Sedgwick Museum of Cambridge and the Booth Museum at Brighton that have been assembled when phosphate mining was at its peak within the English Fens between 1851 and 1900. These fossils discovered whereas workmen have been digging phosphate nodules have been steadily bought to earn a bit bit of additional cash.

It was whereas Smith was inspecting the fossils of shark spines that he made the superb discovery. The fossils have been truly fragments of jaws of toothless pterosaurs, which do certainly resemble shark fin spines, however there are lots of refined variations that enable them to be distinguished.

“One such feature are tiny little holes where nerves come to the surface and are used for sensitive feeding by the pterosaurs. Shark fin spines do not have these, but the early palaeontologists clearly missed these features.”

Smith says: “One such function are tiny little holes the place nerves come to the floor and are used for delicate feeding by the pterosaurs. Shark fin spines should not have these, however the early paleontologists clearly missed these options. Two of the specimens found might be recognized as a pterosaur referred to as Ornithostoma, however one further specimen is clearly distinct and represents a brand new species. It is a palaeontological thriller.

“Unfortunately, this specimen is too fragmentary to be the basis for naming the new species. Sadly, it is doubtful if any more remains of this pterosaur will be discovered, as there are no longer any exposures of the rock from which the fossils came.  But I’m hopeful that other museum collections may contain more examples, and as soon as the Covid restrictions are lifted I will continue my search.”

Smith’s supervisor, Professor Dave Martill, University of Portsmouth, says: “The little bit of beak is tantalizing in that it is small, and simply differs from Ornithostoma in subtle ways, perhaps in the way that a great white egret might differ from a heron. Likely the differences in life would have been more to do with color, call, and behavior than in the skeleton.”

“This find is significant because it adds to our knowledge of these ancient and fascinating flying prehistoric reptiles.”

“Pterosaurs with some of these beaks are higher recognized on the time interval from North Africa, so it will be cheap to imagine a likeness to the North African Alanqa (pictured under).  This is extraordinarily thrilling to have found this thriller pterosaur proper right here within the UK.

“This find is significant because it adds to our knowledge of these ancient and fascinating flying prehistoric reptiles, but also demonstrates that such discoveries can be made, simply by re-examining material in old collections.”

The third creator of the examine was Dr. Dave Unwin, from the University of Leicester’s Centre for Palaeobiology Research.

The outcomes of Roy Smith’s discovery have been printed in The Proceedings of the Geologists’ Association.
