His researches, and those of several authors since then,supplementing and confirming or disproving those of the manyobservers made during the preceding seventy years, have finallydetermined almost perfectly the complete structure of the moretypical ichthyosaurs, enabling us to infer not a little as to theirhabits and distribution in the old Jurassic oceans. Within thepast few years the discoveries of Professor J. C. Merriam of Cali-fornia have likewise added greatly to our knowledge of the earlierichthyosaurs. It may now truthfully be said that of no group ofextinct reptiles do we have a more complete and satisfactory knowl-edge than of the ichthyosaurs. Nevertheless we have yet very much more to learn about theorder Ichthyosauria as a whole—whence they came and how they Text Appearing After Image: Fig. 52.—Ichthyosaurus quadricissus.museum, from Dr. Dreverman. Photograph of specimen in Senckenberg originated; what their nearest kin were among other reptiles; andespecially, more about the connecting links between them andterrestrial reptiles. They have, as an order, so isolated a position,are so widely separated from all other reptiles in structure, that theyhave long been a puzzle to paleontologists. Like the whales andother cetaceans among mammals, we know the ichthyosaurs wellin the plenitude of their power and the fulness of their development,but have yet only an imperfect knowledge of their earlier history,and none whatever of their earliest. However, as will be seenfarther on, the recent discoveries by Merriam have shed much lighton some of the stages of their evolution. So nearly perfectly wereall the later ichthyosaurs adapted to their life in the water that itwas believed by nearly all paleontologists until about a score of years ICHTHYOSAURIA 3 ago that they had desc Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.

The skeleton of Strutbiomimus altus, a small dinosaur from the BeliyRiver series (Cretaceous), Red Deer River, Alberta, Canada, now regarded as ofapproximately the same age as the Judith River series. The unique feature ofthe skull is the total absence of teeth, with a size of skull one-third larger thanthe ostrich and a length of body of about fifteen feet. The position of the skeletonis decidedly that of the opisthotonos which may be regarded as an indication ofdisease. (After Osborn).
