Specimens of Archaeopteryx The end of the feather has an obtuse angle of 110°, while the barbs branch off from the rachis at an angle of around 25°. The barbs branch noticeably into barbules, as in the feathers of modern birds. The base of the feather consists of plumulaceous barbs which are unconnected to one another and result in a down-like appearance. This tuft of down led Griffiths to conclude that "Archaeopteryx" might have been endothermic in that it implies the use of thermal insulation. The feather is clearly asymmetrical, which has been interpreted by many scientists to be a clear indication of
Specimens of Archaeopteryx first time with six other original fossils of "Archaeopteryx" at the "Munich Mineral Show" in October 2009. A first, quick look by scientists indicates that this specimen might represent a new species of "Archaeopteryx". It was found in a limestone bed that was a few hundred thousand years younger than the other finds. The eighth specimen of "Archaeopteryx" was officially announced in February 1996 at a special exhibition at Bavaria’s Naturkunde Museum. Its director, Matthias Mäuser, made the announcement to a surprised audience that the specimen had already been casted and that this was on display in the exhibit. Few
