Dinosaur skeletons are a thing of pure beauty. Being able to see and touch something that has been dead for millions of years instills a sense of wonder; what did they look like, how did they behave, were they like anything we see today? Palaeontology is a science that raises more questions than it answers, but these questions are the ones that drive the science, but also maintain that sense of fascination that no other scientific field can lay claim to.
Every now and then, we are blessed with a true jewel. Many can lay claims to the discovery of a dinosaur bone, even fewer to that of a whole skeleton. Celebrity status is achieved when one finds something that truly stands out, a dinosaur preserved in immortality with flesh, and these are the rarest of all.

Fossils, as we typically think about them, tell us about the death of an animal. The teeth, bones, shells, fragmented pseudopods and other weird and wonderful bits of carcass all only ever reflect one thing: a permanent geological limbo. These types of fossil are known as body fossils. The other major group of fossils, that are generally less common, less researched, less known about, but arguably more important for guiding our understanding of the history of life on Earth, are trace fossils. The study of trace fossils is called ichnology, and the fossils don’t represent death; they represent life, behaviour, activity. They can paint us a picture of a particular event in time, a scene from a play with ghosts of the actors and decayed fragments of script. We’re the audience and the directors, and we have to fill out the act, using the trace fossils draw the concluding freeze frame.
