American Museum novitates ; no. 49(New York City : By order of the Trustees of The American Museum of Natural History, 1922) Osborn, Henry Fairfield, 1857-1935.; Frick, Childs, 1883-1965.Item A generic review of the stenomyline camels. American Museum novitates ; no. 2353(New York, N.Y. : American Museum of Natural History, 1968) Frick, Childs, 1883-1965.; Taylor, Beryl E.Item The Hemicyoninae ; and, An American Tertiary bear. Bulletin of the AMNH ; v. 56, article 1.(New York : Published by order of the Trustees, American Museum of Natural History, 1926) Frick, Childs, 1883-1965.; Rak, Joseph.; Childs Frick Expedition to the Southwest and Mexico (1926)Item Horned ruminants of North America. Bulletin of the AMNH ; v. 69(New York : The American Museum of Natural History, 1937) Frick, Childs, 1883-1965.Item Michenia, a new protolabine (Mammalia, Camelidae) and a brief review of the early taxonomic history of the genus Protolabis. American Museum novitates ; no. 2444(New York, N.Y. : American Museum of Natural History, 1971) Frick, Childs, 1883-1965.; Taylor, Beryl E."Since Protolabis Cope (1876) was described, species of this genus, including the type species have frequently been confused with those of Procamelus and Miolabis. A brief taxonomic history of Protolabis, as well as a clarification of the type species, is given along with characters that distinguish Protolabis from both Procamelus and Miolabis. Michenia agatensis, a specialized camelid of smaller size, near the base of the evolutionary radiation of the protolabines, is also described. Although its ancestry is unknown, Michenia agatensis more closely resembles Dyseotylopus migrans Stock from the upper part of the Sespe Formation of California than any other known Arikareean camelid"--P. 21-22.Item New remains of trilophodont-tetrabelodont mastodons. Bulletin of the AMNH ; v. 59, article 9.(New York : Published by order of the Trustees, American Museum of Natural History, 1933) Frick, Childs, 1883-1965.Item Serbelodon burnhami, a new shovel-tusker from California. American Museum novitates ; no. 639(New York City : The American Museum of Natural History, 1933) Osborn, Henry Fairfield, 1857-1935.; Blick, John C.; Frick, Childs, 1883-1965.Item Tertiary stratigraphy and the Frick Collection of fossil vertebrates from north-central Nebraska. Bulletin of the AMNH ; v. 178, article 3([New York] : American Museum of Natural History, 1984) Skinner, Morris F.; Johnson, F. Walker.; Frick, Childs, 1883-1965."Late Tertiary Valentine and Ash Hollow formations of the Ogallala Group in north-central Nebraska contain two previously unnamed fossiliferous ash-bearing members. These, with four published members, provide a startigraphic framework for large collections of fossils in the Frick Collection in AMNH and other institutions. The Cornell Dam Member (new) in the basal Valentine Formation has salient lithic features and geologic relationships not found in other members of the Valentine. Basal channel sand disconformably overlying the Rosebud Formation contains macro- and microinvertebrate fossils (Norden Fauna, new) that also show the ecological and faunal distinction of this member. Fission track dates suggest that Valentine sediments spanned one and perhaps three million years. The Merritt Dam Member (new) of late Clarendonian to late Hemphillian age, disconformably overlies the Cap Rock Member of the referred Ash Hollow Formation. The Merritt Dam Member is less cliff forming than the Cap Rock Member, contains more volcanic ash and local channel and pond sediments. Tectonic readjustment caused deep channel erosion through the Ogallala into Arikaree rocks on the east flank of the Chadron Arch and eastward into the Cap Rock Member and the Valentine Formation. Sediments filling some of these channels contain vertebrate fossils overlain by vitric tuffs with a fission track date of 9.5 [+ or -] 0.8 Ma. The paleogeomorphology of the Ogallala Group and its depositonal framework is the product of overlapping alluvial fans of at least three paleodrainage systems which filled pre-existing valleys and spread sediments over a vast Great Plains area in Nebraska and South Dakota. In north-central Nebraska widespread aggradation and two short periods of degradation occurred during the Valentinian. Gradual aggradation during the early Clarendonian was followed by intermittent aggradation and degradation during the late Clarendonian and Hemphillian. The stratigraphic allocation and history of 98 collecting localities and documentation of 90 holotypes of fossil vertebrates and 13 plants provide a firm base for continued research. The prinipal aquifer in the Ogallala is the Crookston Bridge Member of the Valentine Formation"--P. 217.Item Tooth sequence in certain trilophodont tetrabelodont mastodons ; and, Trilophodon (Serridentinus) pojoaquensis, new species. Bulletin of the AMNH ; v. 56, article 2.(New York : Published by order of the Trustees, American Museum of Natural History, 1926) Frick, Childs, 1883-1965.; Rak, Joseph.; Childs Frick Expedition to the Southwest and Mexico (1926)
