Figure 4. Vertebral laminae in cervical (top) and dorsal (bottom) vertebrae of Diplodocus. Both vertebrae are in right lateral view. Modified from Hatcher (1901: pl. 3, fig. 14; pl. 7, fig. 7). Abbreviations based on Wilson (1999a): acpl = anterior centroparapophyseal lamina; c = coel; cpol = centropostzygapophyseal lamina; cprl = centroprezygapophyseal lamina; di = diapophysis; hpo = hyposphene; nsp = neural spine; pa = parapophysis; pc = pleurocoel; pcdl = posterior centrodiapophyseal lamina; pcpl = posterior centroparapophyseal lamina; podl = postzygodiapophyseal lamina; poz = postzygapophysis; ppdl = parapophyseal diapophyseal lamina; prdl = prezygodiapophyseal lamina; prpl = prezygoparapophyseal lamina; prz = prezygapophysis; spdl = spinodiapophyseal lamina; spol = spinopostzygapophyseal lamina; sprl = spinoprezygapophyseal lamina. Scale bar = 20 cm.
