Announcing the rather epic 'Glossary of tetrapod tracks' in Palaeontologia Electronica. Three years of work led by Jens Lallensack, and with Guiseppe Leonardi (author of the original '87 Glossary).

Two new Edmontosaurus skeletons with preserved skin just got published by Paul Sereno and collegues. They had a fleshy scaly crest over their back and hoofed feet!
I was lucky enough to see the specimens last summer. The publication is open access:
