Archaeopteryx is sometimes presented as evidence of evolution because the bones have some characteristics reminiscent of reptiles, making it appear to be a so-called "transitional form" between reptiles and birds.
There are two criticisms of the Archaeopteryx. The preeminent British physicist, Sir Fred Hoyle, determined it to be fraudulent. Another criticism is even if Archaeopteryx existed, it was a true bird and not a transitional form suggesting evolution.

First criticism: fraud
In 1983, a half-dozen leading British scientists including Sir Fred Hoyle carefully studied the two best Archaeopteryx specimens, front and back, and declared them to be fakes. They discovered that the front and back slabs of each specimen do not match. They found that an alteration had been made to the left wing as depicted in an 1863 drawing. They concluded that the feather markings had been imprinted by hand. They also found that etching process had used cement blobs. When the scientists requested the ability to use an electronic microscope and carbon-14 dating, the museum refused and withdrew the specimens from the scientists. The same British Museum had been responsible for the Piltdown Man fraud.
Second criticism: not a transitional
The second criticism of the Archaeopteryx, that it is not a transitional form, has been strengthened by the work of anatomist Dr. David Menton suggesting that Archaeopteryx is a true bird with flight feathers, not a transitional form at all. In 1994, an article explained that the Archaeopteryx was essentially a flying bird, with a large cerebellum and visual cortex. The fact that it had teeth is irrelevant to its alleged transitional status -- a number of extinct birds had teeth, while many reptiles do not (the South American hoatzin, Opisthocomus hoazin, also shares with Archaeopteryx clawed digits in its wings, albeit as juveniles). Furthermore, like other birds, both its maxilla (upper jaw) and mandible (lower jaw) moved. In most vertebrates, including reptiles, only the mandible moves.
Evidence for evolution?
In 1993, an article was published in Science magazine arguing that the Archaeopteryx had fully-formed flying feathers (including asymmetric vanes and ventral, reinforcing furrows as in modern flying birds), the classical elliptical wings of modem woodland birds, and a large wishbone for attachment of muscles responsible for the downstroke of the wings
While most evolutionary scientists agree that the flight feathers of Archaeopteryx were essentially modern, several papers since have argued against Feduccia's claims about the anatomy of Archaeopteryx Specimens such as the Thermoplis Specimen  are thought to clearly show that the arms, wishbone, tail, feet, hips, and palate of Archaeopteryx were more like meat-eating theropod dinosaurs than modern birds.
The brain of Archaeopteryx was essentially that of a flying bird, with a large cerebellum and visual cortex. Critics point out that its teeth are irrelevant to its alleged transitional status, as a number of extinct birds had teeth, while many reptiles do not. Furthermore, like other birds, both its maxilla (upper jaw) and mandible (lower jaw) moved. In most vertebrates, including many reptiles, only the mandible moves.
