Running time 2 hours 10 minutes For 2014, the podcast consisted of daily productions averaging about 5 minutes each. The individual episodes for each month are now being assembled into packages for each month, representing various spans of time in the history of the earth.  This episode is the second package, which combines the daily episodes for February, covering the Cambrian Period of the Paleozoic Era. This includes all the individual daily episodes from February 2014. There is variable audio quality in some of the individual recordings, which are conversations between me and other geologists – the nerds in a bar episodes. And I’m leaving the references to specific dates in the podcast so that you can, if you want, go to the specific blog post that has links and illustrations for that episode. They are all indexed on the right-hand side of the blog. As the year continues, there will be new episodes, maybe every week or two, in addition to these monthly assemblies. If you have questions or comments, please let me know, either here on the blog on the ask a question page, or contact me by email at rigibson at earthlink.net. I’ll try to respond. —Richard I. Gibson
