“…Previous reports of Mesozoic marine reptile pathology have been limited to recognition of bone necrosis, of both aseptic [ 12 ] and infectious [ 13 ] aetiology. Aseptic avascular necrosis associated with decompression syndrome is quite common in ancient marine reptiles, including sea turtles [ 14 , 15 ], mosasaurs [ 16 ], ichthyosaurs [ 12 ] and sauropterygians [ 12 , 17 ]. The fossil record of infectious disease in marine reptiles is scarce, limited to bacterial infections in Triassic sauropterygians [ 13 ] and Cretaceous mosasaurs [ 18 , 19 ].…”

Tuberculosis-like respiratory infection in 245-million-year-old marine reptile suggested by bone pathologies

An absence of ancient archaeological and palaeontological evidence of pneumonia contrasts with its recognition in the more recent archaeological record. We document an apparent infection-mediated periosteal reaction affecting the dorsal ribs in a Middle Triassic eosauropterygian historically referred to as ‘Proneusticosaurus’ silesiacus. High-resolution X-ray microtomography and histological studies of the pathologically altered ribs revealed the presence of a continuous solid periosteal reaction with multiple superficial blebs (protrusions) on the visceral surfaces of several ribs. Increased vascularization and uneven lines of arrested growth document that the pathology was the result of a multi-seasonal disease. While visceral surface localization of this periosteal reaction represents the earliest identified evidence for pneumonia, the blebs may have an additional implication: they have only been previously recognized in humans with tuberculosis (TB). Along with this diagnosis is the presence of focal vertebral erosions, parsimoniously compared to vertebral manifestation of TB in humans.

“…Such subsidence is the direct evidence of decompression syndrome [14]. It has been identified in Mesozoic marine reptiles-sea turtles, mosasaurs and ichthyosaurs [14][15][16][17][18], as well as sauropterygians [19]. Avascular necrosis is common in post-Triassic sauropterygians, indicating that they were susceptible to decompression syndrome because of prolonged and repetitive diving behaviour in these marine reptiles.…”

Two types of bone necrosis in the Middle TriassicPistosaurus longaevusbones: the results of integrated studies

Avascular necrosis, diagnosed on the basis of either a specific pathological modification of the articular surfaces of bone or its radiologic appearance in vertebral centra, has been recognized in many Mesozoic marine reptiles as well as in present-day marine mammals. Its presence in the zoological and paleontologic record is usually associated with decompression syndrome, a disease that affects secondarily aquatic vertebrates that could dive. Bone necrosis can also be caused by infectious processes, but it differs in appearance from decompression syndrome-associated aseptic necrosis. Herein, we report evidence of septic necrosis in the proximal articular surface of the femur of a marine reptile, Pistosaurus longaevus, from the Middle Triassic of Poland and Germany. This is the oldest recognition of septic necrosis associated with septic arthritis in the fossil record so far, and the mineralogical composition of pathologically altered bone is described herein in detail. The occurrence of septic necrosis is contrasted with decompression syndrome-associated avascular necrosis, also described in Pistosaurus longaevus bone from Middle Triassic of Germany.

“…Ancient diseases have been recognised for well over a century 1 in dinosaurs 1 2 and other pre-Cenozoic fossil vertebrate groups such as pterosaurs 3 , crurotarsans 4 , plesiosaurs 5 , mosasaurs 6 , ichthyosaurs 7 , turtles 8 , or synapsids 9 . Beside their intrinsic value in revealing a very particular facet of dinosaurian life and death – that is, the existence of certain diseases and their taxonomic and anatomic specificity, as well as of pathogenic agents responsible for them, studies into dinosaurian palaeopathologies have also contributed significantly to a more profound understanding of dinosaur behaviour.…”

Despite documentation of various types of neoplastic pathologies encountered in the vertebrate fossil record, no ameloblastic tumours have been recognised so far. Ameloblastoma is a benign neoplasic tumour with a strong preponderance for the mandible. Here, we report for the first time the presence of an ameloblastoma neoplasm in the lower jaw of a specimen referred to the derived non-hadrosaurid hadrosauroid dinosaur Telmatosaurus transsylvanicus from the uppermost Cretaceous of the Haeg Basin in Romania. The location, external appearance and internal structure of the pathological outgrowth provide clear evidence for the diagnosis of ameloblastoma in Telmatosaurus. This report extends the range of pathologies encountered in hadrosauroid dinosaurs. In addition, recognition of an ameloblastoma neoplasm in a taxon lying close to the origin of ‘duck-billed’ hadrosaurid dinosaurs confirms the predisposition of this clade towards neoplasia pathologies already in its basal members.
