We published a new hadrosaur this week, Pleisolophus warnerensis. Lead by Brad McFeeters based on a specimen found by Wendy Sloboda, of course.

Great to spend time with the basal neoceratopsian, Beg Tse, while visiting IP in Ulaanbaatar last week.

BORN THIS DAY: ELKANAH BILLINGS (May 5,1820-June 14,1896): Canada’s first paleontologist. His boss Sir William Logan wrote him (1869): "Your constant absence from the office is a worrying annoyance, particularly as I have reason to suspect that it does not arrive from rheumatism."

More for May the 4th: colleague Dr David West Reynolds standing at the bluff where Luke looked down on Mos Eisley. In the distance you can just see the palm trees that mark the location of the Well of Souls dig site from Raiders of the Lost Ark. Was this Tunisian adventure really 30 years ago?!

For May the 4th: Me discovering the origin Krayt Dragon prop skeleton in Tunisia back in the early 90’s. The film quarry abandoned this & all the Star Wars props when they left. After I found them (and left them in place!), collectors followed in my footsteps and scoped them up. Hello Ebay!

Look’s like the Sinclair dinosaur is getting a Macy’s Parade balloon this year. Does the green dino have a media presence (TV show, video game) that I’ve missed? #SinclairDinosaur #MacysParade
