Summary

Some animals are specialists at eating particularly tough foods like shells, seeds, and bones. Adaptations for a durophagous diet come in many forms in almost all major groups of life. This episode, we discuss how so many animals tackle tough foods, what behaviors and anatomy help them to do it, and the importance of durophagy for understanding fossils and the history of Earth ecosystems. In the news: fossil boas, walking fish, cooked birds, and early arthropods.

0:00.0	You're listening to the Common Descent Podcast.
0:18.9	Hello, David. Hello, Will.
0:21.6	And hello, listeners.
0:23.1	Welcome to episode 197 of the Common Descent podcast.
0:27.7	Today, we will be discussing durophagy.
0:30.8	Durophagy.
0:31.3	What's that mean?
0:32.5	This means when you eat hard stuff.
0:35.7	Yes, the term durow-like durable eating of tough materials.
0:41.2	Yep, it's a very straightforward definition with a lot of weird ways to do it.
0:46.9	So we'll be discussing the diversity of durophagy this episode.
0:51.6	This can include eating things like shelled things, nuts. Also, bones, which is often in its own category of osteophagy, but we're going to rope it in here because they overlap so much.
1:03.2	The secret subheading of this episode. It's a side topic. Yes. We'll go through what some of the adaptations are for creatures to be able to
1:12.1	eat tough foods, why you'd want to eat tough foods, and what the fossil record of durophagy
1:19.7	looks like. This is a very interesting topic. I love these kinds of diet and adaptation-focused
1:26.6	topics. And we'll be discussing it because it was
1:29.7	requested, both durophagy and osteophagy, was requested by Stuart, Michael, Science Skink, and Joe.
1:38.6	Thanks, everybody. This is a really fun topic to talk about, so this was a great suggestion.
1:43.2	Yes, thank you all. Before we get
1:46.4	into that and before we get to the news, some quick announcements. As always, first and foremost,
1:52.1	we have a Patreon. Sure do. Our Patreon funds the podcast top the bottom. The support from you all
1:57.8	patrons helps us do everything we do here on the podcast.
