Summary

We talk about fossils a lot on this podcast – every episode, in fact – but we rarely take the time to discuss how fossils get the way they are. This is a crucial subject, because the fossilization process is a filter, and nothing comes through the filter unaltered, and many things don’t come through at all. In this episode, we talk about how fossils typically form, how we study this process, and why it’s so important for paleontologists to understand fossilization. In the news: giant croc tracks, injured dino footprints, evolution in cities, and ancient snakey-ness.

0:19.0	Hello, Will. Hello, David.
0:21.3	Hello, listeners, and welcome to the Common Descent podcast.
0:24.9	This is episode 137.
0:28.5	This episode's topic is fossilization.
0:31.5	It's about time we mentioned that.
0:34.0	Yeah, if you're just joining us, the Common Ascent podcast is a podcast about paleontology,
0:38.7	evolution, and the fascinating diversity of life, past and present. And as of the beginning of
0:43.8	2022, we've been doing this podcast for five years. So we figured now's as good a time as any to talk
0:49.6	about what a fossil is. Yeah, you know what? We've kept you eagerly waiting. It's what the people want.
0:57.1	This episode, we are going to go in-depth into fossils, the fossilization process, how fossils are
1:04.7	formed, how the formation of fossils, how that process influences what we end up getting at the end of the process,
1:13.9	and the many ways why it is invaluable for paleontologists to understand the process that the
1:20.2	fossils have gone through before we get the chance to study them.
1:23.9	Yeah, we don't just learn about fossils by what it is, an Armalega, shell, a leaf,
1:29.5	but also by how it got here, how it became a fossil, tells us a bunch, which is, I love it. It's
1:36.6	one of my favorite little aspects of paleontology. Yeah, this is going to be a fun episode. We're
1:41.0	discussing this, this episode, because it is a very important topic to talk about,
1:46.1	but also, because it was requested by a bunch of our listeners, this topic was requested by
1:52.1	Jonathan, Corbin, Dr. J., Thomas, Lewis, Morg, and Mark and Colleen. Wow, good suggestion.
