Whatever happened to the finding 10+ years ago, where scientists found jellified T-Rex bone marrow? It made a huge splash, and they claimed to be able to see structures in the blood, etc, but I haven't heard anything since, and I can't find any follow up research, or I don't know what to google for. Has anyone seen any followups to this?
