“…For instance, a large part of the intraspecific variability in shelled mollusks could be caused by differences in growth rates (Urdy et al 2010a) and development 9 Ammonoid Intraspecific Variability Crônier 2003, 2005). This could also explain certain recurrent patterns in intraspecific variation in the shells of ammonoids and other mollusks with coiled shells (e.g., Dommergues et al 1989;Urdy et al 2010bUrdy et al , 2013Urdy 2015). Extant cephalopods can comprise a high intraspecific variability, particularly in their variable size-at-age, which can be related to intrinsic as well as extrinsic (environmental) factors (Boyle and Boletzky 1996;compare De Baets et al 2015a; Keupp and Hoffmann 2015 for pathologies affecting growth).…”

Because ammonoids have never been observed swimming, there is no alternative to seeking indirect indications of the locomotory abilities of ammonoids. This approach is based on actualistic comparisons with the closest relatives of ammonoids, the Coleoidea and the Nautilida, and on the geometrical and physical properties of the shell. Anatomical comparison yields information on the locomotor muscular systems and organs as well as possible modes of propulsion while the shape and physics of ammonoid shells provide information on buoyancy, shell orientation, drag, added mass, cost of transportation and thus on limits of acceleration and swimming speed. On these grounds, we conclude that ammonoid swimming is comparable to that of Recent nautilids and sepiids in terms of speed and energy consumption, although some ammonoids might have been slower swimmers than nautilids.

“…Yet examination of extant organisms demonstrates that natural selection acts throughout the life cycle, and fitness is significantly impacted by developmental stages that precede maturity (Lindström, 1999). Hence the adaptive strategies employed by a species or lineage can only truly be understood through deeper knowledge of the ontogeny of a species or lineage (Sánchez-Villagra, 2010a; Codron et al, 2013;Urdy et al, 2013;Hone et al, 2016). As a heritable aspect of an animal's biology, developmental data is also a rich source of phylogenetic information, providing insight into evolutionary relationships (e.g., de Queiroz, 1985;Smith, 2000;Asher and Lehmann, 2008).…”

“…Reconstruction of the early ontogeny of extinct organisms is an important subject in paleobiological research and developmental biology (e.g., Donoghue and Dong 2005;Sánchez-Villagra 2012;Urdy et al 2013). Non-mineralized embryos and larval soft-tissues of invertebrates are only preserved in exceptional circumstances (e.g., Donoghue et al 2006;Maas et al 2006), so that the most abundant information about early ontogeny comes from groups with mineralized hard parts secreted at the embryonic or larval stage like ammonoids (Tanabe et al 2008) and other shelled mollusks (Jablonski and Lutz 1983;Nützel et al 2006;Manda and Frýda 2010).…”
