The robot drone exploring EXO159 picked up a series of objects, laid out in various patterns.

We’ve been rummaging in the basement and came across a box of fossilised fixons. These are fossilised remains of creatures that somehow overcame the biosecurity of a Balinger Freight Corporation ship’s hold. During interstellar travel they were subject to an enormous variety of pressures and eventually turned into what feels like small stones. They were found during routine maintenance in 3248 when measures were immediately taken to prevent a similar occurrence.
