Painting Fossil Penguins
Last post, we discussed a new type of pigment discovered in the feathers of living penguins. With a little bit of evolutionary tree-based reasoning, it is possible to project the distribution of this color back into the fossil record as well. In his blog Illuminating Fossils, Dr. Daniel Thomas does just that. Check out the post to see how we can reconstruct the color of the fossil penguin Madrynornis. You can also learn more about Madrynornis in this past post.
