The Cretaceous beds of the Southern Hemisphere contain a peculiar group of Belemnites which differs from all contemporary families previously described in that a ventral groove is never present. Hitherto, the individual species have been recorded either under the generalized name of Belemnitesor else as members of such pre-existing genera as Actinocamax. In 1917, however, the independence of the group was recognized by Woods, who remarked that ? It is probable that the group of species to which B. lindsayibelongs should be regarded as a special section of Belemnites?. |
