The majority of the tank cars exhibited impact damage... on the top portion of at least [one] head. This is not unexpected, as most of these cars came to rest on their sides, thereby bringing the top portion of the heads closer to the ground and increasing the probability of impacts with objects such as rail, couplers, and body bolsters. A full-head shield would have been beneficial, as half-head shields protect only the bottom portion of the head. 1, record 2, English, - full%2Dheight%20head%20shield

La majorité des wagons-citernes montraient des signes de dommages attribuables aux chocs [...] à la partie supérieure d’au moins [une] tête. Cela n’a rien d’inattendu puisque la plupart de ces wagons s’étaient immobilisés sur le côté, ce qui a rapproché la partie supérieure des têtes du sol et a augmenté la probabilité de heurts avec des objets tels que des rails, des attelages et des traverses pivots. Un bouclier protecteur complet se serait avéré utile, puisque les demi-boucliers ne protègent que la partie inférieure de la tête. 1, record 2, French, - bouclier%20protecteur%20complet

The name Arthrodira means "jointed neck" These advanced preditory placoderms had a movable joint between the head(cephalic) and the thoracic(body) armor... The mouth is interesting because as the lower jaw moved down the head shield moved up, thus giving a wide gape. Like all placoderms, they lacked teeth, instead using the sharpened edges of a bony plate as a biting surface. 1, record 9, English, - arthrodira
