This is a close-up of a well-preserved Rhamphorhyncus from the Royal Ontario Museum; it’s from the Middle Jurassic, so it’s at least 161 million years old. Rhamphorhyncus was a pterosaur (so, not a dinosaur, as any fule kno) – apparently, the name means ‘beak snout’.

This particular fossil came from the Bavarian Solnhofen limestone (noted for its beautifully preserved fossils, including Archaeopteryx) and is interesting partly because it has the head of a small fish preserved in the creature’s throat area – presumably the creature’s final lunch.
