Paleopathological features of the Lestodon armatus specimens from Playa del Barco site. (A) MD-PDB-85-144, thoracic vertebra (right lateral view) with a very large osteophyte in the ventral margin of the vertebral body, possibly as part of an intervertebral bone bridge. (B) Detail of the osteophyte on the vertebra shown in A. (C,D) MD-PDB-85-55, cervical vertebra (C, anterior view; D, posterior view) with several osteophytes in the margins of the vertebral body (black arrow) and subchondral erosion in the posterior vertebral endplate (gray arrow). (E,F) MD-PDB-85-52, thoracic vertebra (E, anterior view; F, posterior view) with reduced height, several osteophytes in the margins of the vertebral body (black arrows), and discrete asymmetry in the neural arch. (G,H) MD-PDB-84-8, thoracic vertebra (G, anterior view; H, posterior view) with reduced height, several osteophytes in the margin of the vertebral body (black arrows), discrete arthrosis in the zygapophyses, and asymmetry in the neural arch. (I) MD-PDB-85-145, lumbar vertebrae (anterior view) with several osteophytes in the margin of the vertebral body (black arrow), subchondral erosion in the vertebral endplates (gray arrow), deformity of the vertebral body, and asymmetry of the neural arch. (J) MD-PDB-85-74, caudal vertebra (posterior view) with several osteophytes in the margin of the vertebral body (black arrow), and destruction of the posterior surface of the vertebral body. (K) MD-PDB-05-50, caudal vertebra (posterior view) with subchondral erosion (black arrow). (L) MD-PDB-05-139, rib with irregular bone surface and ossification of ligaments. (M) MD-PDB-85-250, metapodial with osteophytes (black arrow).
