| 0:35.8 | Hello and welcome to I know Dino. I'm Garrett. And I'm Sabrina. And today we'll be talking about Stegoceris, as well as, I think, a record |
| 0:38.8 | amount of dinosaur news. We have 15 items. But first, we want to say a quick thank you to our first |
| 0:43.9 | patron who has kindly pledged to I Know Dino and has helped us to start on our way to our first |
| 0:51.4 | goal of raising enough money to buy new equipment. A few of you have |
| 0:56.3 | mentioned in the past that sometimes it's a little bit difficult to hear us or to hear the people |
| 1:01.6 | that we're interviewing and we've been working on it, but it seems that the best way to handle it |
| 1:07.3 | is to actually upgrade our equipment. So thank you to our first patron. And for other |
| 1:13.2 | listeners, if you would like to support us, then please visit our Patreon page. That's p-A-T-R-E-O-N-Patrian.com |

| 1:49.8 | And it was written by Johann Lindgren and some others. |
| 1:54.5 | So scientists have been trying to figure out what colored dinosaur feathers were ever since they realized that dinosaurs had feathers. |
| 1:57.3 | And up until about 2010, the conventional wisdom was that we might not ever find out |
| 2:02.6 | because a lot of the signature proteins and indicators of what color something is don't really |
| 2:09.9 | survive the fossilization process. As you know, fossilization completely replaces a lot of the material with various minerals. |
| 2:20.2 | So it's never the same color as it was when it was fossilized. |
| 2:23.4 | It usually turns black or, you know, a dark stone color. |
| 2:27.9 | It's not like, you know, a feather gets fossilized and you pull it out and it's a bright blue feather or something. |
