'''Archaeopteryx''' is a transitional [[fossil]] of an animal between a small [[Dinosaur]] and a [[Bird]].  Archaeopteryx is considered a bird.  The animal was about the size of a pigeon or magpie and lived in the [[Late Jurassic]].  Archaeopteryx fossils have been found in German y which in the Jurassic was nearer the equator than now and Europe consisted of islands in  a shallow tropical sea.  Archaeopteryx resembles therapod dinosaurs more closely than it does modern birds.  Notably Archaeopteryx had teeth in its jaws. It had clawed fingers like the modern [[Hoatzin]], The [[DNA]] for these claws may have been present in the ancestors of Hoatzins without being expressed.  Archaeopteryx also had [[vertebrae]] running down its tale.  Archaeopteryx also had broad wings with flight feathers.  It is uncertain whether Archaeopteryx glided or was capable of powered flight.

'''''Archaeopteryx''''' ("Ancient Feather") is a [[fossil]] bird from the [[Jurassic]] that demonstrates the transition from small dinosaur to birdsBecause it had feathers, and was capable of flight, ''Archaeopteryx'' is considered a bird.  The animal was about the size of a pigeon or magpie and lived in the [[Late Jurassic]] of Germany, as fossil remains of it have been found in the [[Solnhofen]] quarries of Bavaria.  In ''Archaeopteryx'''s day, Germany was far closer to the equator, and Europe consisted of islands in  a shallow tropical sea just north of the [[Tethys]] Ocean''Archaeopteryx'' resembles theropod dinosaurs more closely than it does modern birds, especially in the anatomy of its head, fingers, and tail.  Notably ''Archaeopteryx'' had teeth in its jaws. Contrary to popular claims and comparisons, the [[Hoatzin]] is a modern bird not closely related to ''Archaeopteryx'', as the Hoatzin's chicks are not the only (modern) bird chicks to retain claws on the wings, and that the Hoatzin's "fingers" are fused together, as in all other modern birds, and unlike those of ''Archaeopteryx''''Archaeopteryx'' also had broad wings with flight feathers.  It is uncertain whether Archaeopteryx glided or was capable of powered flight, though was probably far more airworthy than hoatzins, which are notoriously poor fliers due to their enlarged, [[rumen]]-like crop which harms their aerodynamic qualities].
