It's from an abstract to an SVP poster:

Kirkland, Agullion-Martinez, Hernandez-Rivera, and Tidwell, 2000. A late
Campanian brachiosaurid proximal caudal vertebra from Coahuila, Mexico:
evidence against a Cretaceous North American sauropod hiatus. Journal of
Vertebrate Paleontology 20 (supplement to Number 3), Abstracts of Papers,
Sixtieth Annual Meeting, pp. 51A-52A.

The vertebra is from the Cerro del Pueblo Fm., with a short centrum wider
than tall (82 mm long x 160 mm high x 179 mm wide), no pleurocoels in
centrum, anteriorly-placed neural arch, no chevron facets, caudal ribs
angled back, overall most comparable to basal titanosauriforms around or
in Brachiosauridae.-Justin
