Excerpt from Pal?ontology, Vol. 2: Cretaceous and Tertiary Fossils
Volume I of the Pal?ontology of California was issued in 1864, the preface bearing date September of that year. It contained descriptions of the Carboniferous and Jurassic fossils by Mr. Meek, and of the Triassic and Cretaceous by Mr. Gabb, and is illustrated by thirty-two plates. The present volume is devoted to the Tertiary and Cretaceous pal?ontology, and is entirely the work of Mr. Gabb. At the time the first volume of the Pal?ontology was published - which was also the first of our Report - it was thought that the whole of our material in this department of the Survey would be comprised in two volumes. Events have proved, however, as might perhaps have been foreseen, that at least three volumes will be required for the proper exposition of our pal?ontological results. The Cretaceous and Tertiary invertebrate material alone requires a volume by itself, and for a third, and possibly a fourth, we have still such additions as have been made to the Jurassic and Triassic, as well as all the fossil plants of various ages, and the vertebrate remains, chiefly of fresh-water and land animals, and of Tertiary age; besides these, are the microscopic fossil organisms, both marine and fresh-water, which are interesting, and will require considerable space for their illustration.
