Podcast 330 - Dinosaur Body Pillow

The gang discusses two papers about the functional morphology of ancient groups of animals. The first paper is a review of how the life position of rangeomorph ediacaran taxa have been reconstructed, and the second paper conducts an actualistic experiment of Oviraptor nesting strategies. Meanwhile, Curt gets activated, James doesn't die, and Amanda relishes in details.   Up-Goer Five (James Edition): The group look at two papers that focus of understanding how things are long dead lived. The first paper talks about strange things that might have either lived standing up or lying down at the bottom of the water which is big and you can not drink. It is hard to tell how these things lived because there are not any around today and so instead we need to look at their form and how they are found in the rock. Most of the things seem to have lived how we thought but one actually was lying down rather than standing up. The second paper looks at how big angry animals without hair kept their round babies and helped them grow by making a form in the ground like they used and putting round babies in it. They looked at how the round babies did by themselves and how they did with a warm bag on top like their final big form. They decide that they probably had the final big form covering the round babies when they were growing but that they did not do it the same was a things that fly and do not have hair today.   References: McIlroy, Duncan.
