  • Possible buoyancy control in some heteromorph ammonite groups is investigated in terms of the position of the siphuncle. Groups investigated include some torticones, ancylocones and orthocones. In Turrilitinae the •idapical position of the siphuncle causes rapid decoupling and may possibly permit the shell to retain significant amounts of cameral liquid, which may be lavourable to a vagile benthonic mode of life. Ancylocones have a very stable floating position in the adult stage, but lateral… CONTINUE READING
