Recent fieldwork in the Tropic Shale of southern Utah has resulted in the recovery of two new specimens of the short-necked pliosaurid Brachauchenius lucasi Williston, 1903.

MNA V9432是一小截下颌，特征与稍大一些且完整很多的9433几乎完全一致。 MNA V9433可以说是相当完整的一具化石，包括一个几乎完整的头骨、12节颈椎、22节背椎、部分肋骨和不完整的肩带、腰带。

2023年10月1日 · MNA V9432 is a juvenile (Albright et al., 2007), and unfused vertebral elements of another specimen (MNA V9433) in Albright et al. (2007: figures 6 to 8) also indicate a juvenile condition with poor ossification. The measurements of cervical and dorsal vertebrae are roughly comparable in the holotype and MNA V9433.

2013年5月7日 · The Eulert pliosaurid remains (FHSM VP-321) housed at the Sternberg Museum of Natural History (Kansas, U.S.A.) include one of the world's best examples of a Cretaceous pliosaurid plesiosaur skull.

MNA V9433, (A) Dorsal view of nearly complete cranium, and (B) dorsal view of complete mandible of the pliosaurid plesiosaur Brachauchenius lucasi. From Albright and others (2013)....

2015年9月1日 · Digital quarry maps of four of the most complete skeletons, all plesiosaurs, were constructed using photographs taken during excavation and field notes on file at MNA. Quarry maps were constructed for MNA V9433 (B. lucasi), V9442 (P. quadratus), V9445 (E. rankini), and V10046 (D. tropicensis).

Other Cretaceous pliosaurid specimens (MNA V9433, SDSM 34991) reveal that the coronoids contribute to the posterior portion of the symphysis in dorsal view (Fig. 10).

Nevertheless, FHSM VP-321 possesses four alveoli in each premaxilla, as in MNA V9433 (Albright, Gillette & Titus, 2007) The maxillary tooth count of FHSM VP-321 (lmx = 19; rmx = 18) is the same...

Brachauchenius (meaning 'short neck') is an extinct genus of pliosaurs that lived during the Late Cretaceous in what are now North America and North Africa. Only one species is known, B. lucasi, initially described by Samuel Wendell Williston in 1903 from a partial fossil skeleton discovered in a quarry in Kansas, United States.

2020年7月18日 · 短颈龙还有一具相对完整的化石MNA V9433在美国出土，其下颌和短颈龙正模也有很大差别。 这次科学家们很谨慎，将其命名为“短颈龙MNA（B.MNA）”（MNA是北亚利桑那博物馆的简称）。
