Amphicyonid carnivorans

11 p. : ill. ; 26 cm.Includes bibliographical references (p. 11)."Endocranial casts of 10 genera of amphicyonids, ranging in age from about 35 my to 10 my, reveal evolutionary trends of increase in relative brain size and expansion and increased folding of the neocortex. Amphicyonids had a distinctive pattern of cerebral convolutions, characterized by the presence of a long ectolateral sulcus, a short sulcus between the caudal ends of the ectolateral and suprasylvian sulci, and a complete, unopercularized ectosylvian sulcus. The ectolateral sulcus is a derived character amphicyonids share with canids, in contrast to a derived feature of basicranial circulation that links amphicyonids to ursids"--P. [1]

23 p. : ill. ; 24 cm.Includes bibliographical references (p. 23)."The rhinocerotoid family Hyrachyidae, which in its last review (Wood, 1934) included four genera and 12 species, is reduced to a subfamily, with one genus and three species, and included in the tapiroid family Helaletidae. Because the European genus Chasmotherium can be traced back to Hyrachyus (via the lineage Hyrachyus modestus (=H. 'stehlini')-Hyrachyus minimus-Chasmotherium cartieri), the monotypic subfamily Chasmotheriinae is transferred to the Helaletidae"--P. 19 & 21
