Awards Killing Game 2x2: Moon of Hope (Game Thread) - Day 4: Lunary Cliffs

Let's examine the Studio for any art pieces resembling bird talons or any files or picks or something that match the scratches on the Train Exhibit tracks.
Nothing in the Studio reasonably matches.
 
Look in the Mines for bats and do the same
 
Are there bats out in the Forest Grounds? Can I find a bat and compare its claws to the scratches?

If there are bats, are there birds? Can I nab a bird or something and compare its talons?
The Forest Grounds are devoid of bats. There's a couple birds. You compare the talons.

They're much smaller than the scratches. No bird could reasonably recreate them.

Look in the Mines for bats and do the same
You look in the mines.

The Pit Mine screeches with disturbance. A swarm of bats flies out. They're all gray with large ears and yellow eyes, and they invariably have nicked ears and wings.

Do the bat claws match the scratches
 
Are there any taxidermied animals, or claws of animals missing from the Rafters?
Do any of the claws in there match the scratches?
You can't tell if there's anything specifically missing, but none of the taxidermined animals match.

You do find a couple fossils that match the shape, if not the size.
