Lost an important keystone of my Ph. D. committee. Don Eicher was an expert on Cret. forams and a great guy who was a great counterpoint to Erle Kauffman, " Captain Cretaceous." W/ Bill Cobban, ammonites & Bill Hay, paleoclimatology I had pretty amazing advisors. @utahgeological

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: science.org/doi/10.1126/sc…
