Item Crocodilian pelvic muscles and their avian and reptilian homologues. Bulletin of the AMNH ; v. 48, article 15.(New York : Published by order of the Trustees, American Museum of Natural History, 1923) Romer, Alfred Sherwood, 1894-Item The ilium in dinosaurs and birds. Bulletin of the AMNH ; v. 48, article 5.(New York : Published by order of the Trustees, American Museum of Natural History, 1923) Romer, Alfred Sherwood, 1894-"One. The saurischian pars preacetabularis ilii is an extension of the external iliac surface. 2. The ornithischian pars preacetabularis is an exaggeration of the anterior iliac spine. 3. The bird pars preacetabularis may have been derived for that of the Ornithischia by a movement medially and the building up of a surface ventral to the original process. 4. The saurischian pars preacetabularis passed dorsal to the pubo-ischio-femoralis internus. That of the Ornithischia did so primitively but later picked up a portion of its origin. In the birds the entire origin of the muscle is from the pars preacetabularis, which is now medial to the muscle, in strong contrast to the saurischian process, which is lateral to it"--P. 144-145.Item The locomotor apparatus of certain primitive and mammal-like reptiles. Bulletin of the AMNH ; v. 46, article 10.(New York : Published by order of the Trustees, American Museum of Natural History, 1922) Romer, Alfred Sherwood, 1894-Item On Spermatodus pustulosus Cope, a coelacanth from the "Permian" of Texas. American Museum novitates ; no. 1017(New York City : The American Museum of Natural History, 1939) Westoll, T. Stanley.; Romer, Alfred Sherwood, 1894-Item The pelvic musculature of saurischian dinosaurs. Bulletin of the AMNH ; v. 48, article 19.(New York : Published by order of the Trustees, American Museum of Natural History, 1923) Romer, Alfred Sherwood, 1894-"The evolution of the pelvis of saurischian dinosaurs is discussed. The marked change in the pubo-ischium is attributed to the changed position of the femur, which has resulted in a shifting of many muscles posteriorly and dorsally. The similarity of the saurischian musculature to that of the Crocodilia is pointed out. A restoration of the pelvic musculature of Tyrannosaurus is attempted"--P. 617.Item The Pennsylvanian tetrapods of Linton, Ohio. Bulletin of the AMNH ; v. 59, article 2.(New York : Published by order of the Trustees, American Museum of Natural History, 1930) Romer, Alfred Sherwood, 1894-
