… and I’m guessing that if you read this blog, you like at least one of these things.

Today sees the publication of a paper that I’m particularly pleased with, partly because it’s so far outside my usual area: The Concrete Diplodocus of Vernal — a Cultural Icon of Utah (Taylor et al. 2023). Let’s jump in by taking a look at the eponymous concrete Diplodocus:

Taylor et al. (2023:figure 5). The completed outdoor Diplodocus mount in a rare color photograph. Undated (but between 1957 and 1989). Scanned by Eileen Carr for the J. Willard Marriot Digital Library, image ID 415530. Used by permission, Uintah County Library Regional History Center.

(On of the things I love about this photo is that it has the same 1950s energy as the Carnegie Tyrannosaurus mount that I posted a while back.)

This paper tells the neglected story of how the Utah Field House museum in Vernal acquired the original Carnegie Diplodocus molds in 1957, after they had languished, unloved and overlooked, in their Pittsburgh basement for forty years; how they were used to cast a Diplodocus from actual concrete (one part cement to three parts aragonite, for those who care); how the molds then went on a series of adventures, never actually yielding another complete skeleton, before being lost or destroyed; how the concrete cast stood for 30 years before the harsh Utah weather degraded it past the point of safety; how it was then used to make a fresh set of molds, and replaced by a new lightweight cast taken from those molds; and how the molds were then used to create a new generation of Diplodocus casts.

It’s a long and fascinating story with lots of twists and turns that I necessarily omitted from that summary — which is why it runs to 27 pages in the lavishly illustrated PDF. I urge you to go and read it for yourself: we wrote it to be an engaging story, and I hope it’s a pretty easy read. (My wife found it interesting, and she once literally fell asleep while I was running a talk to solicit her feedback, so that’s really something.)

This paper was submitted on 2 November 2022, so it’s taken less than five months to go through peer review, editorial processes, typesetting with four(!) rounds of page proofs and online publication. This of course is how it should always be — it’s a bit stupid that I am drawing attention to this schedule like it’s something extraordinary, but the truth is that it is extraordinary. At any rate that makes it fifteen times faster than my long-delayed (mostly my fault) paper on neck incompleteness (Taylor 2022).

I got so deeply into this paper when I was lead-authoring it that the phrase “the Concrete Diplodocus of Vernal” really started to echo around in my head. That is why the paper ends by expressing this wish:

Our dearest hope for this paper is that it inspires someone to create a Dungeons and Dragons module in which the Concrete Diplodocus of Vernal is a quest artifact with magical powers.

But Mike, you ask — how did you, a scientist, find yourself writing a history paper? It’s a good question, and one with a complicated answer. Tune in next time to find out!
