In his classic monograph, Hatcher (1901) illustrated the cervical vertebrae of the Diplodocus carnegii holotype CM 84 with beautiful drawings: But only in lateral view. Other plates show photos in lateral, anterior and posterior views, and these are useful even though they’re much less clear than the drawings.

Up top there is a commercially obtained cast sculpture of a thumb claw of Megaraptor. Down below is an unpainted urethane cast of one of my favorite inanimate objects in the universe: OMNH 780, a thumb claw of Saurophaganax.

Last night London and I spent the night in the Natural History Museum of Los Angeles County (LACM), as part of the Camp Dino overnight adventure. So we got lots of time to roam the exhibit halls when they were–very atypically–almost empty.

Another raw photo from the road. The Morrison fossils from the Oklahoma panhandle were dug up and prepped out by  WPA workers in the 1930s, and their preparation toolkit consisted of hammers, chisels, pen-knives, and sandpaper.

Here’s an update from the road–get ready for some crappy raw images, because that’s all I have the time or energy to post (with one exception). Here’s OMNH 1331. It’s just the slightly convex articular end off a big vertebra, collected near Kenton, Oklahoma, in 1930s by one of J. Willis Stovall’s field crews.

The original version of the PDF of our new paper (Wedel and Taylor 2013) had a couple of obvious errors: Kaatedocus was misspelled in the caption to Figure 7 (as Kaatedocu), and the submission date was given as June 24, 2012, not the correct date of June 14. Both of these errors were introduced during […]

Today sees the publication of my big paper with Mike on neural spine bifurcation, which has been in the works since last April. It’s a free download here, and as usual we put the hi-res figures and other supporting info on a sidebar page.

Last Tuesday Mike popped up in Gchat to ask me about sauropod neck masses.  We started throwing around some numbers, derived from volumetric estimates and some off-the-cuff guessing.

Well, this is rad. And adorable. Brian Switek, whom we adore, commissioned a fuzzy juvenile sauropod from Niroot, whom we adore, for his (Brian’s) upcoming book, My Beloved Brontosaurus , which I am gearing up to adore. And here is the result, which I adore, borrowed with permission from Love in the Time of Chasmosaurs. There is much to like here. Here’s my rundown: Small forefeet that are the correct shape: good.
