5 The evolutionary origin of birds has always been a subject of considerable debate. Birds and flying reptiles have delicate, lightweight skeletons which do not fossilize well - hindering studies on how the birds evolved. The first bird fossil to be found was a feather, which was discovered in 1860 in a limestone quarry in Bavaria. The feather was given the name Archaeopteryx, which is Greek for 'ancient feather'. A year later an almost complete skeleton of Archaeopteryx was discovered in the same quarry, with the feathers and other fine structures preserved in minute detail.

6 The skeleton showed several features which are intermediate between reptiles and birds, suggesting that Archaeopteryx and the other birds evolved from a dinosaur similar to the Velociraptor featured in the film 'Jurassic Park'. Seven partial or complete Archaeopteryx skeletons have now been found, and they are still among the most famous, and scientifically valuable, fossils.
