Podcast 16 - TUBE FEET!!!!!

In this episode of Palaeo After Dark, the group talks about an interesting and enigmatic fossil species from the Burgess Shale called Siphusauctum gregarium, which looks somewhat like a crinoid but is possibly completely unrelated. The group also gets sidetracked into conversations about  echinoderms, the importance of the Burgess Shale, and shipping grandfather clocks on the Oregon Trail.
