PBS Eons has a new episode. This one is about squids and discusses taphonomy and what happened to their missing fossils.
Check out Otherwords, a new show about language & linguistics! https://youtu.be/d2UccTPnl4w It might surprise you but cephalopods have a pretty good fossil record, with one major exception. If squids were swimming around in the same oceans as their closest cousins, where did all the squids go?
Thanks to Franz Anthony for the cephalopod illustrations featured in this episode! http://franzanth.com/
