PLATE 24. 
Megalosaurus Bucklandii ; nat. size. 
Three anterior dorsal vertebre : p, parapophysis, or lower transverse process: z, acces- 
sory tubercle contributing some attachment to the head of the rib: d, diapo- 
physes, or upper transverse process, fractured, which gave attachment to the 
tubercle of the rib: 5, oblique buttress extending from the parapophysis to 
the diapophysis, and contributing to the support of the neural platform: z, 
the prozygapophysis, رم‎ the zygapophysis, forming the ends of the neural 
platform and articulating the neural arches of the vertebræ with each other, 
ns, the neural spine of the foremost of these vertebre, ns, the neural spine of 
the second vertebra; it expands at its extremity, overhangs the anterior 
shorter spine, and developes a strong bony plate from its back part which 
fixes it to 2", the similarly developed and modified spine of the third vertebra. 
The extraordinary size and strength of the spines of these anterior dorsal 
vertebre, indicate the great force with which the head and jaws of the 
Megalosaurus must have been used.
