Summary

Leaves. They’re everywhere. They’re the main photosynthesizing organs of plants, and they’re the main source of green on our green-and-blue planet. Leaves come in a truly dizzying variety of shapes, sizes, and specialized functions, and their early evolution laid the foundation for terrestrial ecosystems as we know them. This episode, Aly joins us yet again to talk about the anatomy and diversity of leaves and the incredible information we can learn from leaves in the fossil record. In the news: croc cousins, horned dinosaurs, dinosaur myths, and fish brains.

0:00.0	You're listening to the Common Descent Podcast.
0:19.0	Hello, Will. Hello, David. Hello, everybody out there, and welcome to Common Descent, a podcast about paleontology, evolution, life history, and so on.
0:27.5	This is episode 195.
0:30.2	Longtime listeners of the podcast will know that that five at the end means it's a plants episode.
0:34.5	Woo!
0:34.9	This episode, our topic is leaves.
0:38.7	Very important piece of plant functions.
0:42.5	Plant tech.
0:43.2	Plant tag.
0:44.2	This is a very key part of plants.
0:46.5	Now, it is the middle, we're in Crock and Snake Month territory.
0:51.2	And when we looked at the schedule, usually, you know, the last couple years we've done Crock and Snake Month, we did a Croc-themed episode for Croc Month and then a

1:01.7	falls right in between them. Yep. So there will be a snake-themed episode. Stay tuned next episode.
1:06.5	We'll talk more about snakes. But we got to put a plants episode right there in the middle.

1:28.4	Crocs last episode and I'm talking about snakes next episode, we might as well give Allie
1:33.6	the chance to talk about her favorite thing, and that's Leaves. Yes, it is. This is Allie's
1:38.5	whole deal. Allie loves leaves. Allie's a leaf person. We will talk about what leaves are, how they function, why they're
1:46.3	important, what they mean for us in the fossil record, both in terms of what they tell us about
