Fig. 11 in Pathological phalanges in a camarasaurid sauropod dinosaur and implications on behaviour

Fig. 11. Comparison of the normal development of articular surfaces of phalanges of diplodocid sauropod SMA 0087 (php II-1, A) with the pathological elements of camarasaurid sauropod SMA 0002 (php III-1, B); both from the Upper Jurassic Morrison Formation, Howe Ranch, Wyoming, USA. Note the considerable extension of the lateral spurs in SMA 0002.
