I've followed the news over the new species Oculudentavis with interest. The initial find was stunning; the follow up discussion around whether or not this is a basal therepod, a stem bird, or (quite possibly, it seems) a lizard was a fascinating insight into modern palaeontology. But the debate around the ethics of its provenance in Myanmar amber has eclipsed all of that. Mark Witton has a great argument here for why a boycott on amber from the region should be considered, but I can't help but worry about the knowledge that could be lost if legitimate scientific channels withdraw. It's a tricky situation.
