Hello and welcome to I know Dino. I'm Garrett.

0:34.6

And I'm Sabrina.

0:38.8

And today we have an interview with Jack Horner, which we're really excited about,

0:44.7

and a discussion about mayasora peopelsorum, as well as a lot of dinosaur news.

0:50.5

So first in the news, there's a story from gotscience.org by David Hohn,

0:55.7

and he describes the giraffe a titan that's in the museum for nature in Berlin.

1:03.7

It has been installed there since the 1930s, but then it was disassembled, cleaned, repaired, and remounted back in 2007.

1:09.4

Back when it was originally mounted, they pierced many of the bones with metal rods in order to hold it up,

1:12.0

and that allowed them to mount it in a way that looked a little bit more, you know, realistic, I guess, even though you'd never see a dinosaur's

1:17.2

bones like that. But it, you know, wasn't covered in metal. It was a little more hidden. But obviously,

1:22.8

that's not the best way to preserve fossils drilling a bunch of holes in it. So when they put it back up, they built a complete metal framework around it, and they

1:32.1

use that basically to hang the bones off of it rather than pierce them.

1:36.2

So there's a lot of wrapping metal around it.

1:38.9

You see more metal, but obviously better for the fossils.

1:41.2

The new style also allows them to easily remove individual bones

1:45.9

for research or cleaning, and while they had all the bones out, they took the opportunity to

1:51.5

digitally scan key bones for research. We've talked to some about those 3D models that they have.

1:57.8

The article also goes into some details about different fossils, quote-unquote fossils,

2:03.0

that you might see in a typical mounted dinosaur. Because complete fossilized skeletons are very rare,
