A 3D recreation of the capital of the Aztec empire, with comparisons with modern day Mexico City.

When you think of animation, do you think of modern technology and computers? What if we showed you an animation dating back 14,000 years?

Discovered in 1868 in France's Laugerie-Basse rock shelter, this tiny (only 3.1 cm) bone disc is like a prehistoric 'gif'!

There is a mountain goat drawing on both sides of the disc and a hole in the middle. When you quickly turn the disc, it creates an optical illusion as if the goat is moving, due to the perfect proportions of the drawings and the alignment of the ridge lines.

Here is a primitive but impressive predecessor of modern animation.

Apologies for the silly clickbait headline.

This is on one of my mother's maples. What is it and what should she do about it?

And by a while ago, I mean 2017, but I just stumbled upon it and remembered no one ever was able to identify it for me back then.

Edit: Forgot to say this is Indiana, USA.
