(A) Posterior view, (B) anterior view, (C) left lateral view Replica of one of the fossil elements of Huehuecanauhtlus', temporarily stored in the Paleontology Laboratory of the Universidad Michoacana (UMSNH) within the framework of the XVIII National Congress of Paleontology, held at the end of September 2024 in Morelia, Michoacán. The replica was a courtesy loan made by Dr. Ángel A. Ramírez-Velasco. The element consists of a vertebra and a dorsal rib of Huehuecanauhtlus tiquichensis (IGM 6253) with pathological conditions derived from a premortem or perimortem fracture in the rib, in association with a singular sclerosis and costovertebral ankylosis that probably originated from spinal and costal osteomyelitis, which would have severely affected the nervous system of the individual (Ramírez-Velasco et. al. 2016).[1] Abbreviations: cd, circular depression; ctj, costo-transversal joint; cvj, costo-vertebral joint; cvm, costo-vertebral mass; ee, elliptical erosion; el, cortical elevation; rf, rib fracture.

Panoramic view of Plateosaurus engelhardti skeletons "Skelett 1" (left) and "Skelett 2" (right, collection number GPIT/RE/7288) from Trossingen, Germany, on exhibit at the museum of the Institute for Geosciences of the Eberhard-Karls-University Tübingen, Germany. "Skelett 2" is a nearly complete individual, "Skelett 1" is a composite from 2 individuals. Mounts created under the direction of Friedrich von Huene. This is a panoramic image created from several photographs, and thus has unusual visible and invisible edge distortions.
