Upper Jurassic Period
A bone originally classified as a coelurosaurian fibula by Huene in 1926 has
been re-examined and interpreted as a wing phalange II of a large pterosaur.
The specimen comes from Solothurn Turtle Limestone, a Late Jurassic sediment
of Kimmeridgian age, from an old quarry near St. Niklaus, Solothurn,
Switzerland.
