, The different patterns of homeomorphy in ammonites; numbers 1 to 4 are different 1607 species; circles, squares and triangles are different phenotypes; letters a and b are different 1608 processes; dash-lines separate different environments, vol.8

, This is the case for example with the Lenicostites gen. nov. 1612 and Hemihoplitinae; B and C, homeomorphy by parallel evolution is given when the 1613 descendants of the same ancestral phenotype (species 1, square) have evolved in trajectories 1614 towards a similar morphology (circle). Here, the same common developemental processes 1615 was involved independently (a -intrinsic factor), A, homeomorphy by convergence is 1609 given by evolution of independent processes, p.1617, 1961.

, In that case (see the 1619 example of Physodoceras in Hantzpergue, 1987), ammonite lineages 2 and 3 have evolved 1620 iteratively in platform edge environment (whatever the processes involved, D, iterative evolution can be given by adaptive convergence

, E, iterative evolution can be also given by evolutionary crisis 1622 (punctuated event of proteromorphosis type -intrinsic factor), which leads to the 1623 reappearance of ancestral phenotype (circle), whatever the processes involved, a or b. This 1624 special case of parallel evolution shifted in time is known, for example, Gregoryceras, 1625 which finally repeated the morphology known in its ancestor Peltoceratoides (see Bonnot, vol.1626, 1995.
