The crushed palate and lower face of the holotype of Proconsul nyanzae has been prepared using the acetic acid technique. The prepared and conserved fragments have been restored to their natural positions using a synthetic cement and polyethylene glycol wax (Carbowax 4000) to fill the gaps. Preparation revealed the inferior margin of the right orbit, the inferior border of the nasal bones, and a posterior divergence of the palate which has now been corrected. The restored face of P. nyanzae shows the orbits to have been wider apart than those of Proconsul major, both absolutely and relatively, and that it had a long narrow nose and palate. It differs from Proconsul africanus, which has the shortest and broadest face of all Proconsul species, and from P. major which has a much longer narrower face.

Archaeopteryx lithographica might be regarded as the most important zoological species known, fossil or recent. Its importance lies not in that its transitional nature is unique-there are many such transitional forms at all taxonomic levels-but in the fact that it is an obvious and comprehensible example of organic evolution. There have been recent allegations that the feather impressions on Archaeopteryx are a forgery. In this report, proof of authenticity is provided by exactly matching hairline cracks and dendrites on the feathered areas of the opposing slabs, which show the absence of the artificial cement layer into which modern feathers could have been pressed by a forger.
