Paleontology and Evolutionary Biology

This memoir is supplementary to the author’s former communications to the Royal Society on the same subject, and comprises an account of some important additions which he has lately made to our previous knowledge of the osteological structure of the colossal reptiles of the Wealden of the South-east of England. The acquisition of some gigantic and well-preserved vertebræ and bones of the extremities from the Isle of Wight, and of other instructive specimens from Sussex and Surrey, induced the author to resume his examination of the detached parts of the skeletons of the Wealden reptiles in the British Museum, and in several private collections; and he states as the most important result of his investigations, the determination of the structure of the vertebral column, pectoral arch, and anterior extremities of the Iguanodon. In the laborious and difficult task of examining and comparing the numerous detached, and for the most part mutilated bones of the spinal column, Dr. Mantell expresses his deep obligation to Dr. G. A. Melville, whose elaborate and accurate anatomical description of the vertebræ is appended to the memoir. The most interesting fossil remains are described in detail in the following order.
