dc.description.abstract "The chief distinguishing characters of the American Miocene genera as now understood may be given briefly as follows: Hypohippus: Both deciduous and permanent series of teeth brachyodont, no cement; both upper series without external ribs on paracone and metacone; metaloph simple and undivided, but strongly united with the ectoloph; no crochet; metaconid and metastylid of lower teeth undivided or slightly divided by a shallow notch at the summit of an unworn tooth. Parahippus: Both deciduous and permanent series of teeth brachyodont, deciduous series without cement, permanent series sometimes lightly cemented; deciduous upper molars with prominent external ribs on paracone and metacone; metaloph strongly united with ectoloph; crochet well developed, uniting more or less strongly with the protoconule; metastylid strongly developed, with well-marked groove separating it from the metaconid. Merychippus: Deciduous molars brachyodont with little or no cement; permanent series short hypsodont, fully cemented. Protohippus: Both deciduous and permanent series of teeth hypsodont and strongly cemented; permanent series moderately long-crowned; crowns much curved; protocone and protoconule strongly united; fossettes or cement lakes wide transversely with open loops, and usually with comparatively simple enamel borders. Neohipparion: Both deciduous and permanent series of teeth hypsodont and strongly cemented; teeth of permanent series usually longer crowned and upper teeth less curved than in Protohippus; protocone free to near its base as in Hipparion"--P. 194. en_US

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
