In today's episode we chat with Yara Haridy, a bone-obsessed palaeontologist who has just finished her PhD in Germany. We chat about all things bone - how they evolved, what the first bony mudsucking critters were and how to work out the age of a beastie from its bones. Oh, and Emma talks about her obsession with Venus flower basket sponges. Yara can be found on Twitter @Yara_Haridy.

PalaeoParty! is a biweekly interactive podcast about palaeontology. Each week we invite a new palaeontologist guest to join our hosts, Dr Emma Dunne, Dr Chris Dean and Dr Thomas Clements, as we laugh about weird fossils, odd science and whatever else pops into their brains! PalaeoParty! is unlike other podcasts because we live stream each episode on Twitch so you can chat and ask our guests questions in real time! Find our schedule at our website: https://palaeoparty.weebly.com/ or at https://twitch.tv/palaeoparty

This season is generously funded by the Paleontological Society Outreach and Education Grant.
