Soc. 564 The ordinal position of the paraconid in the ontogeny may seem rather strange. 1904, etc. [see metaconid]. 1922 W. K. Gregory Origin & Evolution Human Dentition i. 84 It seems probable that the paraconid, metaconid, and entoconid, arose in situ on the slopes of the protoconid. 1970 Nature 25 July 356/1 The presence of a paraconid in such a position is more characteristic of fossil lemuroids and omomyoids. 1975 [see metaconid]. |
