Extract

Recently, aguirre urreta and Riccardi (1988) have shown that Calliscaphites andinus Leanza, 1970, belongs in Myloceras Spath, and raised Calliscaphites as a subgenus for crioceratid coiled members of this genus. In doing so, they noted (p. 611) that, although Whitehouse (1926) had previously described Aleteceras as a genus for crioceratid coiled species that are now (Wright, 1957) included in Myloceras, none of these species appeared to have been unequivocally shown to have a crioceratid mode of coiling throughout life. This view had been strengthened by their reading of McNamara (1978). They did, however, note that “crioceratid coiling in Aleteceras would imply validation of this taxon as a senior synonym of Calliscaphites.”
