Dinosaur National Monument quarry map
February 25, 2015
The Carnegie Quarry, at Dinosaur National Monument, near Jensen, Utah, is arguably the most impressive dinosaur-fossil exhibit anywhere in the world — a covered, semi-excavated quarry that’s absolutely packed with big dinosaur fossils.
It’s also notoriously difficult to photograph: too big to fit into a single photo, and with poor contrast between the bones and matrix. This is the best picture I’ve found of part of it (from here) …
… although this one (from here) conveys the scale better:
It’s one of the great sadnesses of my life that I’ve yet to visit DNM.
The quarry is historically important: discovered by Earl Douglass in 1909, it yielded among other specimens CM 3018, the holotype of Apatosaurus louisae and the principle subject of Gilmore’s (1936) monograph.
I’ve only recently become aware (thanks, Matt!) of Ken Carpenter’s (2013) detailed treatment of the history, sedimentology and taphonomy of the quarry — an important work that deserves to be widely read. Pages 10-14 are largely taken up with parts A-E of figure 10 — a big multi-page map of the quarry, showing the location of its most important specimens. Unfortunately, the five sections of this figure are all at slightly different scales in the PDF. I’ve rescaled them and pasted them together into a single big (4387 × 1210) image which I reproduce here:
Update (six hours later)
I just heard from Ken Carpenter, who created the illustration. He has kindly sent me the full-resolution version — which is four times as big as the one I extracted from the PDF — and gave me permission to post it here on SV-POW! under the CC By licence. So here it is!
Second update (12 March 2015)
Over on the Extinct Monsters blog, Ben Miller has published The Carnegie Quarry Diaspora. It’s a beautiful illustrated survey of some of the most important specimens to have come out of this quarry, including no fewer than seven important sauropod individuals.
