The animal has already left
A fossil footprint asks for a different verb from a fossil bone. Try writing the label before drawing the animal.
Here is a small exercise for an imaginary museum. There are two display cases, and the labels have not been written. One contains a fossil bone. The other contains a fossil footprint. Give each a sentence that begins: something survived.
The first answer comes readily: part of an animal survived. It needs qualification about fossilisation, but its grammar feels at home in a museum case. The second is stranger. The animal need not have died there at all. Something it did has entered the collection.
The National Park Service distinguishes body fossils from trace fossils. Bones, teeth and shells belong to the first category; footprints, burrows and trails are examples of the second. Trace fossils preserve evidence of biological activity. The distinction is not simply between a solid object and an impression: a cast or impression made by bodily remains can still be a body fossil.
That last point saves our imaginary curator from an attractive but unhelpful shortcut. A hollow is not automatically a trace, and a lump is not automatically a body. The question concerns what produced the evidence. Shape alone does not supply the category.
Now write the second label again, without naming an animal. Something stepped here. It is a very small sentence, yet it has a scene inside it. There was contact between a living body and a surface. The case contains neither an intact actor nor a complete stage. Their encounter is what has become available.
I like the change in the visitor’s task. A bone invites a reconstruction of something with parts. A footprint invites a reconstruction with a verb. That is my shorthand for looking, not a division of scientific labour: bodies can inform accounts of behaviour, and traces can inform accounts of their makers. But as an opening invitation, the two labels set the imagination moving differently.
Suppose the museum illustrator is waiting beside the cases with a magnificent animal drawing. It could make the footprint easier to notice. It could also settle the scene too early. Once a large, colourful creature occupies the panel, the small mark may become merely its signature. The drawing has answered who before the label has finished asking what happened.
The Geological Survey of Western Australia notes that identifying a trace’s maker can be difficult, while traces can still inform us about ancient behaviour and environments. An uncertain name does not empty the second case. There is a difference between lacking a complete cast list and lacking an event.
For this imaginary exhibition, I would try a caption with the verb in large type and the proposed maker in smaller, qualified text. Not because names are unimportant, but because the display should let the evidence do something before the illustration takes over. A visitor might first follow the contact, then consider who could have made it.
There is a quiet reversal here. A museum commonly asks us to stop so that we can inspect what has been kept. This case keeps evidence of something that did not stay. Its subject is not obliged to be present as a specimen. The animal’s departure belongs comfortably in the account.
Put the two unfinished labels side by side once more. Something survived: a part. Something survived: an activity’s mark. Neither is the whole animal, and neither needs to be demoted to a defective version of the other. They offer different ways for the past to be specific.
I would leave the second case with that modest sentence intact: something stepped here. Not everything is known. Something happened.
