Palaeocast is a free web-based resource of excellent podcasts by professional palaeontologists exploring the fossil record and the evolution of life on earth. It also covers new stories, recordings and live-stream links to conferences and videos. I presented a poster on the subject of an ankylosaur pelvic shield as part of the SVPCA 2015 and did a quick interview for them as part of the event coverage (I'm at the end, 53 mins in!) http://www.palaeocast.com/svpca/ The second image shown here is the cellular structure mentioned found sandwiched in between the pelvic shield and ilium. Do check out the other programmes, including episode 53 for a bit more ankylosaur action.
