Summary

The evolution of mineralized tissues is responsible not only for the incredible success and diversity of vertebrate animals, but also for their extraordinarily informative fossil record. This episode, we explore the detailed anatomy of bones and their deep evolutionary history, we touch on some of the ways they’re important for paleontology, and we take some time to discuss the secrets that can be found inside of ancient bones. In the news: croc vs pterosaur, hominin diets, ears and gills, and reptile food.

0:00.0	You're listening to the Common Descent Podcast.
0:19.0	Hello, Will. Hello, David.
0:21.4	Hello, everybody, and welcome to Common Descent, a podcast about paleontology evolution and the history of life on Earth.
0:28.2	This is episode 210.
0:30.5	This episode is about bones.
0:33.5	Bones.
0:34.3	That's right.
0:35.3	Eight years and 200 episodes into our podcast about paleontology,
0:40.0	we decided that it's high time we talk about bones. I'm sure a lot of you have been very
0:45.0	confused for the last 200 and some odd episodes. People are going to finally know what we're
0:49.8	talking about. We're usually so good at defining terms. We skip this one majorly. You keep using this word and you just never, I don't know. This episode, we are going to do an in-depth exploration of bones. We will talk about what bones are, how they work. We'll get into some of the evolutionary history of bones, and we will talk about
1:13.5	some of the ways that bones are useful for paleontologists, and we'll get into some specific
1:19.7	methods and techniques that paleontologists can use to get as much information as possible
1:24.6	out of the bones of ancient animals. This is one of my favorite kind of topics we get to do where we get to dive into a seemingly
1:31.6	mundane topic. And it turns out to just be so cool.
1:35.9	This is another one of those that if we do it right, this will change the listening experience
1:40.6	for almost every other episode of this podcast. Yes.
1:46.8	So this is how we get people to keep listening to us.
1:48.5	Yeah, now you have to go back.
1:50.5	It's like you're looking for Easter eggs.
1:54.5	Like when you watch a mystery movie and you're like, oh, yeah, exactly.
1:56.0	Like, now I see.
