Hints: reptile Europe Pangea North America Atlantic limestone quarried Solnhofen Bavaria fine-grained pterosaurs

As reptiles conquered the skies above ancient Europe, dramatic changes were affecting the western shores. Pangea continued to disintegrate, Europe was tearing itself away from what is now North America. This separation gave birth to one of the world's great oceans, the Atlantic.
As this ocean grew, pterosaurs were not the only creatures exploring the air. And the most famous evidence for that is found here, in Solnhofen in Bavaria. This tiny community is famous for the unique qualities of the local rock. The limestone quarried here is extremely fine-grained and can be worked into thin and very light slabs.
