W. G. Barrett, Geological facts; or, the crust of the earth… (1855)
“ In vain does Geology, after showing us the fossil trilobite and coral, unfold the volume of the Old Red Sandstone, and show us there the fossil remains of fish—so perfect that we might imagine them casts rather than fossils. In vain does Geology open its vast Oolitic system, and show us there other forms of extinct life in fossil insects, tortoises, mighty saurians, and huge iguanodons. In vain does Geology lay bare the Chalk, with its marine deposits; and the Tertiary formation, with its enormous theroid mammalia, far surpassing in size the largest animals we are acquainted with. ”
