Specimens of Archaeopteryx precipitated the first surge of widespread knowledge of the specimen across Europe. In the subsequent years of the 19th century, the London specimen was subject to a number of analyses by other researchers of historical importance, including Thomas Huxley, Othniel Charles Marsh, Wilhelm Dames, and Bronislav Petronievics. Much of this early study was relevant to controversy surrounding the possible taxonomic divisions of "Archaeopteryx" specimens. The London specimen is of obvious special importance because it was the first "Archaeopteryx" skeleton discovered. By coining the name "Archaeopteryx", meaning "ancient wing", von Meyer had declared the animal to be a bird. Despite the
Dinosaur tooth data that has been collected through dinosaur dental histological studies are typically unavailable through other means and has provided us with a more in-depth understanding on their biology. One of the most significant findings is that despite differences in their appearance, dinosaur teeth are essentially composed of the same dental tissues found in modern mammals, crocodilians and other amniotes, suggesting that these tissues first evolved in a common ancestor and has been retained ever since. Another finding is that the lines of von Ebner can be counted similar to tree rings to determine the age of a tooth. Furthermore, as
