File:Eubrachythoracid thoracic armours.jpg

English: Trunk armors of eubrachythoracid arthrodires scaled to the same ventral shield length, showing the proportionally deeper trunk armor of Dunkleosteus. A, Coccosteus cuspidatus (drawn from Miles and Westoll, 1968 and ROM VP 52664); B, Compagopiscis croucheri (modified from Gardiner and Miles, 1994); C, Plourdosteus canadensis (modified from Vézina, 1988); D, Eastmanosteus calliapsis (modified from Dennis-Bryan, 1987); E, Dunkleosteus terrelli (CMNH 7054, a small adult); F, Heintzichthys gouldii (modified from Carr, 1991); G, Bungartius perissus (modified from Dunkle, 1947); H, Amazichthys trinajsticae (modified from Jobbins et al., 2022). Dotted line in D–H, represents posterior margin of pectoral fenestra. Lines at far right represent trunk height of D. terrelli for easy comparison. The posterior dorsolateral is slightly restored for crushing in D to better represent the typical morphology of D. terrelli. Trunk canal in Bungartius omitted due to uncertain morphology (Dunkle, 1947: p. 110). Scale equals 10 cm.
