The 366 daily episodes in 2014 were chronological snapshots of earth history, beginning with the Precambrian in January and on to the Cenozoic in December. You can find them all in the index in the right sidebar. In 2015, the daily episodes for each month were assembled into monthly packages, and a few new episodes were posted. Now, the blog/podcast is on a weekly schedule with diverse topics, and the Facebook Page showcases photos on Mineral Monday and Fossil Friday. Thanks for your interest!

February 13. The Burgess Shale, again

Today’s podcast is a brief report on my personal favorite Burgess Shale animals: Anomalocaris and Opabinia.

Anomalocaris - up to 6 feet long

Opabinia - less than 3 inches long

And here is a link to the February 2014 news report mentioned in the podcast (thanks to Colleen Elliott for finding this). And another link, with photos.

UPDATE: from predator to filter feeder
