Comparative Analysis of Some Morphometric Characters in Two Sepiolids: , (NAEF, 1916) and , (Orbigny992; Bello, 1995). The only difference referred to by Naef (1923) is that the tentacles of . are smaller than those of . and bear much smaller suckers. However this is evident only when specimens of equal size from the two species are examined together. The purpose of this paper is to verify whether

Plasticity of Developmental Timing as the Underlying Cause of High Speciation Rates in Ammonoidsology among taxa are due to small changes in developmental timing, and an unusually high number of progenic dwarf spinoff taxa occur in this clade, indicating that larger-scale changes in ontogenetic timing are also common. It seems, then, that the developmental program of this ammonite clade was ex

Pathologic Gigantism in Middle Carboniferous Cephalopods, Southern Midcontinent, United Statesre dominated by ammonoids in unusual abundance. These assemblages represent single horizons and localities where most individuals of a species are of strikingly similar size, apparently mature, and seem to reflect mass mortality, possibly related to reproduction (semelparity). Associated with these

Conch Ultrastructure and Septal Neck Ontogeny of the Belemnite , (Duvaliidae) from the Valanginian oposed of long mural parts of the septa and/or of the prismatic layer of the primordial rostrum. The first septum is prismatic; others are formed by the nacreous layer Type 2 (Mutvei, 1970), which in sections gives an impression of a granular structure; the mural parts of the septa show tabular nacre

Cephalopod Development and Evolution evolutionary biology are viewed on the background of three special problems of cephalopod morphology: the reproductive system of octopods, the lower beaks of coleoids and ammonites, and the arm crown of the coleoids.
