Fused mid‐caudal vertebrae in the titanosaur Uberabatitan ribeiroi from the Late Cretaceous of Brazil and other bone lesions

Abstract: Bone pathology in the titanosaur dinosaur Uberabatitan ribeiroi from the Marília Formation (Bauru Group, Late Cretaceous) of Uberaba city (Minas Gerais State, Brazil) is analysed here. They include two fused procoelous mid‐caudal vertebrae (CPPLIP‐1020) and a haemal arch (CPPLIP‐1006) of the middle section of the tail with a healing fracture callus. The analyses of the caudal vertebrae CPPLIP‐1020 of Uberabatitan permit us to recognize the following signs, based on CT scan and external macroscopic observations… Show more

“…Relative to the extent of the fossil record, pathological specimens have generally been infrequently recognized, and involvement of sauropods, even less reported (Hatcher ; Holland ; Rothschild & Berman ; Rothschild & Molnar ; Lovelace ; Martinelli et al . ). We believe that pathology in dinosaurs is more frequent than published and that these abnormalities are usually unnoticed or underestimated.…”

“…More recently, Martinelli et al . () reported fused vertebrae in the Brazilian titanosaur Uberabatitan ribeiroi , interpreted either as the result of a spondyloarthropathy process or an infection. Osteomyelitis, however, has not been previously reported in sauropod dinosaurs.…”

“…14-15) could be evidence of frequent occurrence of hind limb injuries in Eoscapherpeton asiaticum. In modern cryptobranchids such as Cryptobranchus, limb injuries are the most common physical abnormalities in wild populations (Miller and Miller, 2005). The proposed main cause of limb injuries in Cryptobranchus is intraspecific ag- gression during the reproductive season (e.g., defending of nesting sites), because fresh injuries were found only during the reproductive season (namely in August and September) (Hiler et al, 2005;Miller and Miller, 2005).…”

Taking into account the phylogenetic position of Eoscapherpeton as a member of the cryptobranchid clade and their aquatic lifestyle (see Skutschas, 2009Skutschas, , 2013, the reason for the frequent occurrence of hind limb injuries in E. asiaticum could be the same (intraspecific aggression during reproductive season), and this behavioral element could have appeared early in the evolution of cryptobranchids, i.e., at least in the Late Cretaceous.…”
