Scientific illustration

Scientific illustration plays a key role in specimen-based paleobiological research. Anatomically accurate reconstructions of extinct organisms serve two main purposes. First, illustrations allow us to graphically summarize the morphological information preserved in body fossils, and help us to visualize extinct organisms as actual living beings. Second, illustrations represent an excellent resource for teaching and outreach. It is much easier to communicate the biological complexity of an extinct animal to a general audience through an aesthetically attractive reconstruction, than by solely examining the fossil data, as the latter is often incomplete or distorted by preservation biases. This section showcases a combination of schematic diagrams, artistic impressions, and professional scientific reconstructions that accompany our published manuscripts.
