Episode 47: Lobopodians

It's been quite a week for lobopodians! First off, we've had the redescription of Hallucigenia by Dr Martin Smith. This enigmatic fossil from the Burgess Shale typifies the difficulty palaeontologists have had in interpreting some of the earliest animals in the fossil record. It has famously been reconstructed upside-down and is now shown to also have been back-to-front too! Dr Smith joins us to tell us about the observations, including some new anatomical characters, that put an end to the uncertainty of the orientation of this animal. Secondly, there's a older and more heavily-armoured lobopodian from the early Cambrian Xiaoshiba biota of China that we've got the exclusive on. Collinsium ciliosum is described today and we're also joined by one of the lead authors Dr Javier Ortega-­Hernández.
