Specimens of Archaeopteryx colouration and patterning of the plumage cannot be drawn with certainty from this study. In 2011, graduate student Ryan Carney and colleagues performed the first colour study on an "Archaeopteryx" specimen with the fossil of this single feather. Using scanning electron microscopy technology and energy-dispersive X-ray analysis, the team was able to detect the structure of melanosomes in the fossil. The resultant structure was then compared to that of 87 modern bird species and was determined with a high percentage of likelihood to be black in colour. While the study does not mean that "Archaeopteryx" was entirely black, it does
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
