I overhear the palaeontologist conversing with a remote colleague. They seem to be discussing some of their findings, their tone puzzled.

...do not understand what has become of these ancient creatures. The fauna here has no evidence of four legs.

The alien turns their attention to me, indicating a diagram on their datapad. A quadrupedal beast is displayed. They tap at the four limbs, shaking their head and frowning. Name seems to want me to find evidence of this four-legged creature - or one of its descendants.

It is very strange, friend. The bones we have found are so different from the creatures today. The ancestor has four legs. Fauna now has none! Can you help us learn more?
