My fourth year as fossil mammal curator at the @nhm-london.bsky.social has come and gone! Another busy one, from fieldwork in Greece to digging through archives. We've cleared clutter, documented specimens, and shared the wonder. Exciting new research and gallery work somehow squeezed in too! ☺️

I'm headed to Argentina to the Ischigualasto for my millionth week of fieldwork of the year. Gonna find a complete articulated Pisanosaurus.

And this means that it is becoming impossible to resolve relationships. Systematics and taxonomy is going backwards in dinosaur palaeontology, in my opinon

Show Post

Yes. As a consequence, we seem to be headed back to the bad old days of dinosaur taxonomy, where every isolated scrap gets a name. This is causing a vast proliferation of genera based on indeterminate and fragmentary material that overwhelmes phylogenetic analyses with missing data (1/2)

This is Dubreuillosaurus. Known from one fossil, the holotype. Described in Journal of Vertebrate Paleontology in 2002. Accessioned into France's national collection, the Muséum national d'histoire naturelle in Paris, as MNHN 1998-13. Now up for auction. HOW IS THIS POSSIBLE?
