Leptostomia begaaensis

Leptostomia is an extinct genus of pterosaur that lived during the Cenomanian and possibly Albian stages of the ?Early-Late Cretaceous period in what is now Morocco, North Africa. Leptostomia is known from only two isolated rostrum (beak) fragments. In 2021, paleontologist Roy E. Smith and colleagues named the type and only known species, Leptostomia begaaensis, based on these fossils. Leptostomia is a small pterosaur, with the complete skull length estimated between 6 and 20 centimeters, making it much smaller than many contemporary pterosaurs. The beak of Leptostomia is remarkably long, narrow, and compressed from the top down, a morphology unseen in any other known pterosaur.
