Posterior cervical vertebra of a juvenile Diplodocus

September 11, 2017

We’ve not done many picture-of-the-week posts here recently. Let’s change that! Here’s a lovely little specimen that we saw in BYU on the 2016 Sauropocalypse trip.

Wedel and Taylor (2013), Figure 7. BYU 12613, a posterior cervical of Diplodocus, in dorsal (top), left lateral (left), and posterior (right) views. It compares most favourably with C14 of D. carnegii CM 84/94 (Hatcher, 1901: plate 3) despite being only 42% as large, with a centrum length of 270 mm compared to 642 mm for C14 of D. carnegii.

(At least, this is catalogued as Diplodocus. Jaime Headden suggested, and Emanuel Tschopp corroborated, the idea that it’s more likely Kaatedocus.)

    I’ve been enjoying the recent spate of actual sauropod vertebrae on SV-POW lately!
    (Keep fighting the good fight for OA, though!)

    Thanks, Andrew, appreciated! We’re enjoying it, too.
